The charge on the capacitor at t = 0.05 s is approximately 6.5756 C, and it never reaches zero.

In an LRC-series circuit, the charge on the capacitor can be calculated using the equation:

q(t) = q(0) * [tex]e^(-t/RC)[/tex]

where q(t) is the charge on the capacitor at time t, q(0) is the initial charge on the capacitor, R is the resistance, C is the capacitance, and e is the mathematical constant approximately equal to 2.71828.

Given the values: L = 0.05 H, R = 3 Ω, C = 0.02 F, E(t) = 0 V, q(0) = 7 C, and i(0) = 0 A, we can substitute them into the formula:

q(t) = 7 *[tex]e^(-t / (3 * 0.02)[/tex])

To find the charge on the capacitor at t = 0.05 s, we substitute t = 0.05 into the equation:

q(0.05) = 7 * [tex]e^(-0.05 / (3 * 0.02)[/tex])

Calculating this value using a calculator or software, we find q(0.05) ≈ 6.5756 C.

To determine the first time at which the charge on the capacitor is equal to zero, we set q(t) = 0 and solve for t:

0 = 7 * [tex]e^(-t / (3 * 0.02)[/tex])

Simplifying the equation, we have:

[tex]e^(-t / (3 * 0.02)[/tex]) = 0

Since e raised to any power is never zero, there is no solution to this equation. Therefore, the charge on the capacitor does not reach zero in this circuit.

In summary, the charge on the capacitor at t = 0.05 s is approximately 6.5756 C, and the charge on the capacitor never reaches zero in this LRC-series circuit.

The given compound logical proposition is a tautology.

To prove that the given compound logical proposition is a tautology, we need to show that it is always true regardless of the truth values of its individual propositions.

The given compound proposition is:

(asp) →→→ (r^-p)

Let's break it down and analyze it step by step:

The expression "asp" represents the conjunction of the propositions "a" and "sp". We don't have the exact definitions of "a" and "sp," so we cannot make any specific deductions about them.

The expression "(r^-p)" represents the implication of "r" and the negation of "p". This means that if "r" is true, then "p" must be false.

Now, let's consider different scenarios:

Scenario 1: If "r" is true:

In this case, "(r^-p)" is true because if "r" is true, then "p" must be false. Therefore, the compound proposition evaluates to true, regardless of the truth values of "asp".

Scenario 2: If "r" is false:

In this case, "(r^-p)" is also true because the implication "r → ¬p" is true when the antecedent is false. Again, the compound proposition evaluates to true, regardless of the truth values of "asp".

Since the compound proposition is true in both scenarios, regardless of the truth values of its individual propositions, we can conclude that it is a tautology.

Note: It's important to have the exact definitions of the individual propositions and their logical relationships to provide a more precise analysis.

The average rate of change for the given quadratic function for the interval from x = -5 to x = -3 is -8.

The correct answer to the given question is option B.

The given quadratic function is shown below:f(x) = x² + 3x - 10

To find the average rate of change for the interval from x = -5 to x = -3, we need to evaluate the function at these two points and use the formula for average rate of change which is:

(f(x2) - f(x1)) / (x2 - x1)

Substitute the values of x1, x2 and f(x) in the above formula:

f(x1) = f(-5) = (-5)² + 3(-5) - 10 = 0f(x2) = f(-3) = (-3)² + 3(-3) - 10 = -16(x2 - x1) = (-3) - (-5) = 2

Substituting these values in the formula, we get:

(f(x2) - f(x1)) / (x2 - x1) = (-16 - 0) / 2 = -8

Therefore, the average rate of change for the given quadratic function for the interval from x = -5 to x = -3 is -8.

If Amy and Amanda's restaurant bill comes to $22.80 and they decide to tip the waitress 15%, the waitress will receive $3.42 as a tip.

To calculate the tip amount, we need to find 15% of the total bill. In this case, the total bill is $22.80. Convert the percentage to decimal form. To do this, we divide the percentage by 100. In this case, 15 divided by 100 is equal to 0.15. Therefore, 15% can be written as 0.15 in decimal form.

Multiply the decimal form of the percentage by the total bill. By multiplying 0.15 by $22.80, we can find the amount of the tip. 0.15 × $22.80 = $3.42.

Therefore, the waitress will receive a tip of $3.42. In total, the amount the waitress will receive, including the tip, is the sum of the bill and the tip. $22.80 (bill) + $3.42 (tip) = $26.22. So, the waitress will receive a total of $26.22, including the tip.

We have found that the solutions of the given equation satisfying x > 0, y > 0, and z > 0 are (2, 1, 2√2) and (6, 1, 2√3).

The given equation is x² + 3y² = z², and the conditions are x > 0, y > 0, and z > 0. We need to find all the solutions of this equation that satisfy these conditions.

To solve the equation, let's consider odd values of x and y, where x > y.

Let's start with x = 1 and y = 1. Substituting these values into the equation, we get:

1² + 3(1)² = z²

1 + 3 = z²

4 = z²

z = 2√2

As x and y are odd, x² is also odd. This means the value of z² should be even. Therefore, the value of z must also be even.

Let's check for another set of odd values, x = 3 and y = 1:

3² + 3(1)² = z²

1.) The z-score is -1.29. An NBA player whose height is 74 inches is shorter than the average.

2.) The z-score is 1.55. An NBA player whose height is 85 inches is taller than the average.

3.) A z-score of 3.6 equates to a height of approximately 93.40 inches. There are likely no NBA players this tall, so it is highly improbable that the player's z-score is 3.6.

To calculate the z-score, we use the formula: z = (x - μ) / σ, where x is the observed value, μ is the mean, and σ is the standard deviation.

1.) For a height of 74 inches:

The z-score is calculated as follows:

z = (74 - 79) / 3.89 ≈ -1.29

Interpretation: An NBA player whose height is 74 inches has a z-score of -1.29. This means that their height is approximately 1.29 standard deviations below the mean. They are shorter than the average NBA player.

2.)For a height of 85 inches:

The z-score is calculated as follows:

z = (85 - 79) / 3.89 ≈ 1.55

Interpretation: An NBA player whose height is 85 inches has a z-score of 1.55. This means that their height is approximately 1.55 standard deviations above the mean. They are taller than the average NBA player.

3.) For a reported z-score of 3.6:

To find the corresponding height, we rearrange the formula: x = z * σ + μ

x = 3.6 * 3.89 + 79 ≈ 93.40 inches

Interpretation: A reported z-score of 3.6 corresponds to a height of approximately 93.40 inches. We can determine the number of NBA players at this height by calculating the proportion of players with a z-score greater than or equal to 3.6.

Since the z-score is quite high, it is highly unlikely that there are any NBA players of this height. Therefore, it is improbable that the player's claim of having a z-score of 3.6 is accurate.

The sample variance for the given set of data is 5.33 (rounded to two decimal places).

To calculate the sample variance, we need to follow the formula: Σ(X-X)² / (n-1), where Σ represents the sum, (X-X) represents the deviations from the mean, and n represents the number of data points.

Given the deviations from the mean for the specific set of data as -4, -1, -1, 0, 1, 2, and 3, we can calculate the sample variance as follows:

Step 1: Calculate the squared deviations for each data point:

(-4)² = 16

(-1)² = 1

(-1)² = 1

0² = 0

1² = 1

2² = 4

3² = 9

Step 2: Sum the squared deviations:

16 + 1 + 1 + 0 + 1 + 4 + 9 = 32

Step 3: Divide the sum by (n-1), where n is the number of data points:

n = 7

Sample variance = 32 / (7-1) = 32 / 6 = 5.33

Therefore, the sample variance for the given set of data is 5.33 (rounded to two decimal places).

a. There are 27 students enrolled in physics but not in mathematics.

b.  There are 12 students who study neither physics nor mathematics.

a. To find the number of students enrolled in physics but not in mathematics, we can use the principle of inclusion-exclusion.

Let's denote:

M = Number of students enrolled in Mathematics

P = Number of students enrolled in Physics

C = Number of students enrolled in Chemistry

We are given the following information:

M = 45

P = 47

C = 53

M ∩ P = 20 (Number of students enrolled in both Mathematics and Physics)

M ∩ C = 22 (Number of students enrolled in both Mathematics and Chemistry)

P ∩ C = 19 (Number of students enrolled in both Physics and Chemistry)

Total number of students (n) = 100

We can use the formula: n = M + P + C - (M ∩ P) - (M ∩ C) - (P ∩ C) + (M ∩ P ∩ C)

Substituting the given values, we have:

100 = 45 + 47 + 53 - 20 - 22 - 19 + (M ∩ P ∩ C)

Simplifying the equation, we get:

100 = 84 + (M ∩ P ∩ C)

Since we know that there are 4 students who are not enrolled in any of the mentioned courses, we can substitute (M ∩ P ∩ C) with 4:

100 = 84 + 4

Solving for the number of students enrolled in physics but not in mathematics (a):

P - (M ∩ P) = 47 - 20 = 27

Therefore, there are 27 students enrolled in physics but not in mathematics.

b. To find the number of students who study neither physics nor mathematics, we can use the principle of inclusion-exclusion again.

The number of students studying neither physics nor mathematics can be calculated as:

Total number of students - (M + P - (M ∩ P) + C - (M ∩ C) - (P ∩ C) + (M ∩ P ∩ C))

Substituting the given values, we have:

100 - (45 + 47 - 20 + 53 - 22 - 19 + 4) = 100 - 88 = 12

Therefore, there are 12 students who study neither physics nor mathematics.

Step-by-step explanation:

all the functions with the "exponent" -1 mean inverse function (and not 1/function).

the inverse function gets a y value as input and delivers the corresponding x value as result.

so,

[tex]g { }^{ - 1} (0)[/tex]

gets 0 as input y value. now, what was the x value in g(x) that delivered 0 ?

4

that x value delivering 0 as y was 4.

so,

[tex]g {}^{ - 1} (0) = 4[/tex]

the inverse function for a general, continuous function get get by transforming the original functional equation, so that x is calculated out of y :

h(x) = y = 4x + 13

y - 13 = 4x

x = (y - 13)/4

and now we rename x to y and y to x to make this a "normal" function :

y = (x - 13)/4

so,

[tex]h {}^{ - 1} (x) = (x - 13) \div 4[/tex]

a combined function (f○g)(x) means that we first calculate g(x) and then use that result as input value for f(x). and that result is then the final result.

formally, we simply use the functional expression of g(x) and put it into every occurrence of x in f(x).

so, we have here

4x + 13

that we use in the inverse function

((4x + 13) - 13)/4 = (4x + 13 - 13)/4 = 4x/4 = x

the combination of a function with its inverse function always delivers the input value x unchanged.

so,

(inverse function ○ function) (-3) = -3

Answer:

[tex]\text{g}^{-1}(0) =\boxed{4}[/tex]

[tex]h^{-1}(x)=\boxed{\dfrac{x-13}{4}}[/tex]

[tex]\left(h^{-1} \circ h\right)(-3)=\boxed{-3}[/tex]

Step-by-step explanation:

The inverse of a one-to-one function is obtained by reflecting the original function across the line y = x, which swaps the input and output values of the function. Therefore, (x, y) → (y, x).

Given the one-to-one function g is defined as:

[tex]\text{g}=\left\{(-7,-3),(0,2),(1,3),(4,0),(8,7)\right\}[/tex]

Then, the inverse of g is defined as:

[tex]\text{g}^{-1}=\left\{((-3,-7),(2,0),(3,1),(0,4),(7,8)\right\}[/tex]

Therefore, g⁻¹(0) = 4.

[tex]\hrulefill[/tex]

To find the inverse of function h(x) = 4x + 13, begin by replacing h(x) with y:

[tex]y=4x+13[/tex]

Swap x and y:

[tex]x=4y+13[/tex]

Rearrange to isolate y:

[tex]\begin{aligned}x&=4y+13\\\\x-13&=4y+13-13\\\\x-13&=4y\\\\4y&=x-13\\\\\dfrac{4y}{4}&=\dfrac{x-13}{4}\\\\y&=\dfrac{x-13}{4}\end{aligned}[/tex]

Replace y with h⁻¹(x):

[tex]\boxed{h^{-1}(x)=\dfrac{x-13}{4}}[/tex]

[tex]\hrulefill[/tex]

As h and h⁻¹ are true inverse functions of each other, the composite function (h o h⁻¹)(x) will always yield x. Therefore, (h o h⁻¹)(-3) = -3.

To prove this algebraically, calculate the original function of h at the input value x = -3, and then evaluate the inverse of function h at the result.

[tex]\begin{aligned}\left(h^{-1}\circ h \right)(-3)&=h^{-1}\left[h(-3)\right]\\\\&=h^{-1}\left[4(-3)+13\right]\\\\&=h^{-1}\left[1\right]\\\\&=\dfrac{1-13}{4}\\\\&=\dfrac{-12}{4}\\\\&=-3\end{aligned}[/tex]

Hence proving that (h⁻¹ o h)(-3) = -3.

[ 2 1 1 ] [ X ] [ 4 ]

[ 0 1 -0.1] * [ Y ] = [ 0.4]

[ 3 2 1 ] [ Z ] [ 2 ]

```

Performing Gaussian elimination:

1. Row 2 = Row 2 - 0.1 * Row 1

```

[ 2 1 1 ] [ X ] [ 4 ]

[ 0 0 0 ] * [ Y ] = [ 0 ]

[ 0 0 0 ] * [ Y ] = [ 0 ]

[ 0 1/2 -1/2] [ Z ] [ -2 ]

```

3. Row 3 = 2 * Row 3

```

[ 2 1 1 ] [ X ] [ 4 ]

[ 0 0 0 ] * [ Y ] = [ 0 ]

[ 0 1 -1 ] [ Z ] [ -4 ]

```

Now, we have reached an upper triangular form. Let's solve the system of equations:

From the third row, we have Z = -4.

Substituting Z = -4 into the second row, we have 0 * Y = 0, which implies that Y can take any value.

Finally, substituting Z = -4 and Y = k (where k is any arbitrary constant) into the first row, we can solve for X:

2X + 1k + 1 = 4

2X = 3 - k

X = (3 - k) / 2

Therefore, the solution to the system of equations is:

X = (3 - k) / 2

Y = k

Z = -4

The solutions provided, namely y=e^(-5x), y=(5x+1)e^(-5x), and y=xe^(-5x), satisfy the given third-order linear homogeneous differential equation. Furthermore, these solutions are linearly independent.

To verify that each solution satisfies the given differential equation, we need to substitute them into the equation and check if the equation holds true. Let's consider each solution in turn.

For y=e^(-5x):

Taking derivatives, we find y'=-5e^(-5x), y''=25e^(-5x), and y'''=-125e^(-5x). Substituting these into the differential equation, we have:

(-125e^(-5x)) + 10(25e^(-5x)) + 25(-5e^(-5x)) = -125e^(-5x) + 250e^(-5x) - 125e^(-5x) = 0. Thus, y=e^(-5x) satisfies the differential equation.

For y=(5x+1)e^(-5x):

Taking derivatives, we find y'=(1-5x)e^(-5x), y''=(-10x)e^(-5x), and y'''=(10x-30)e^(-5x). Substituting these into the differential equation, we have:

(10x-30)e^(-5x) + 10(-10x)e^(-5x) + 25(1-5x)e^(-5x) = 0. Simplifying the equation, we see that y=(5x+1)e^(-5x) also satisfies the differential equation.

For y=xe^(-5x):

Taking derivatives, we find y'=e^(-5x)-5xe^(-5x), y''=(-10e^(-5x)+25xe^(-5x)), and y'''=(75e^(-5x)-50xe^(-5x)). Substituting these into the differential equation, we have:

(75e^(-5x)-50xe^(-5x)) + 10(-10e^(-5x)+25xe^(-5x)) + 25(e^(-5x)-5xe^(-5x)) = 0. Simplifying the equation, we see that y=xe^(-5x) also satisfies the differential equation.

To test the set of solutions for linear independence, we need to check if no linear combination of the solutions can produce the zero function other than the trivial combination where all coefficients are zero. In this case, since the given solutions are distinct, non-proportional functions, the set of solutions {e^(-5x), (5x+1)e^(-5x), xe^(-5x)} is linearly independent.

Therefore, the solutions provided satisfy the differential equation, and they form a linearly independent set.

Carolyn's marginal propensity to consume is 0.83.

The Marginal Propensity to Consume (MPC) is a measure of the proportion of an additional dollar of income that a household consumes rather than saves. In this question, we need to calculate Carolyn's MPC based on the given data.

The formula to calculate MPC is: MPC = Change in Consumption / Change in Income

To find the MPC, we first need to determine the change in consumption and the change in income. Given that Carolyn's consumption has increased by $5,000, we have:

Change in Consumption = $5,000

Carolyn's income has increased from $32,000 to $38,000, resulting in a change in income of $6,000.

Change in Income = $6,000

Using these values, we can now calculate Carolyn's MPC:

MPC = Change in Consumption / Change in Income

MPC = $5,000 / $6,000

MPC = 0.83

Therefore, Carolyn's marginal propensity to consume is 0.83.

The area of the portion of the sphere defined by the conditions x² + y² + z² = 25 and 3 ≤ z ≤ 5 is approximately 56.55 square units.

To find the area of the portion of the sphere, we need to consider the given conditions. The equation x² + y² + z² = 25 represents the equation of a sphere with a radius of 5 units centered at the origin (0, 0, 0).

The condition 3 ≤ z ≤ 5 restricts the portion of the sphere between the planes z = 3 and z = 5.

To calculate the area of this portion, we can visualize it as a spherical cap. A spherical cap is formed when a plane intersects a sphere and creates a curved surface. In this case, the planes z = 3 and z = 5 intersect the sphere, forming the boundaries of the cap.

The area of a spherical cap can be calculated using the formula A = 2πrh, where A is the area, r is the radius of the sphere, and h is the height of the cap. In this case, the radius of the sphere is 5 units, and the height of the cap can be found by subtracting the z-values of the planes: h = 5 - 3 = 2 units.

Substituting the values into the formula, we get A = 2π(5)(2) = 20π ≈ 62.83 square units. However, this value represents the total surface area of the spherical cap, including both the curved surface and the circular base. To find the area of just the curved surface, we need to subtract the area of the circular base.

The area of the circular base can be calculated using the formula A = πr², where r is the radius of the base. In this case, the radius is the same as the radius of the sphere, which is 5 units. Therefore, the area of the circular base is A = π(5)² = 25π.

Subtracting the area of the circular base from the total surface area of the spherical cap, we get 62.83 - 25π ≈ 56.55 square units, which is the area of the portion of the sphere defined by the given conditions.

The formula for calculating the area of a spherical cap is A = 2πrh, where A is the area, r is the radius of the sphere, and h is the height of the cap.

This formula applies to any spherical cap, whether it's a portion of a full sphere or a segment of a larger sphere. By understanding this formula, you can accurately calculate the area of various spherical caps based on their dimensions and the given conditions.

The function f(x,y) = (y² - x² / y² + x²)² is discontinuous at the origin (0,0) but continuous along any smooth curve that does not pass through the origin.

The function f(x,y) = (y² - x² / y² + x²)² is defined for all values of x and y except where the denominator is equal to 0, since division by 0 is undefined.

Thus, the function is discontinuous at the points where y² + x² = 0,

Which corresponds to the origin (0,0) in the plane.

However, we can check the continuity of the function along any curve that does not pass through the origin.

In fact, we can show that the function is continuous along any smooth curve that does not intersect the origin by using the fact that the function is the composition of continuous functions.

To see this, note that f(x,y) can be written as f(x,y) = g(h(x,y)), where h(x,y) = y² - x² and g(t) = (t / (1 + t))².

Both h(x,y) and g(t) are continuous functions for all values of t, and h(x,y) is continuously differentiable (i.e., smooth) for all values of x and y.

Therefore, by the chain rule for partial derivatives, we can show that f(x,y) is also continuously differentiable (i.e., smooth) along any curve that does not pass through the origin.
This implies that f(x,y) is continuous along any curve that does not pass through the origin.

The values of a and b satisfying a² = 6² (mod N) can be found using the provided equations and modular arithmetic.

The values of a and b satisfying a² = 6² (mod N) can be determined using the given data.

To find the values of a and b satisfying a² = 6² (mod N), we need to analyze the provided equations and modular arithmetic. Let's break down the given information:

We are given N = 198103, and we have the following congruences:

1189² ≡ 27000 (mod 198103)

16052686 ≡ 2378²108000 (mod 198103)

2815² ≡ 105 (mod 198103)

From equation 1, we can observe that 1189² ≡ 27000 (mod 198103), which means 1189² - 27000 is divisible by 198103. Therefore, a - b = 1189 - 27000 is a factor of N.

Similarly, from equation 3, we have 2815² ≡ 105 (mod 198103), which implies 2815² - 105 is divisible by 198103. So, a - b = 2815 - 105 is another factor of N.

By calculating the greatest common divisor (gcd) of N and the differences a - b obtained from equations 1 and 3, we can find the common factors of N and factorize it.

Radius is the distance between the center and the point on the circle.

Use distance formula to find the radius:

Substitute r for d and given coordinates to get:

Alan will receive $16,800, Betty will receive $18,900, and Carol will receive $21,000.

In order to calculate the amount each person will receive, we need to determine the total investment made by Alan, Betty, and Carol. The total ratio is 8+9+10=27.

To find Alan's share, we divide his ratio (8) by the total ratio (27) and multiply it by the total profit ($56,700). Therefore, Alan will receive (8/27) * $56,700 = $16,800.

For Betty, we follow the same process. Her ratio is 9, so her share will be (9/27) * $56,700 = $18,900.

Similarly, for Carol, her ratio is 10, so her share will be (10/27) * $56,700 = $21,000.

To summarize, Alan will receive $16,800, Betty will receive $18,900, and Carol will receive $21,000 from the total profit of $56,700 based on their respective investment ratios.

To find a 12-digit number that has 3 as a factor but not 9, and 4 as a factor but not 8, we need to consider the prime factorization of the number. We know that a number is divisible by 3 if the sum of its digits is divisible by 3. For a 12-digit number, the sum of the digits can be at most 9 × 12 = 108. We want the number to be divisible by 3 but not by 9, which means that the sum of its digits must be a multiple of 3 but not a multiple of 9.
To find a 12-digit number that has 4 as a factor but not 8, we need to consider the prime factorization of 4, which is 2². This means that the number must have at least two factors of 2 but not four factors of 2. To satisfy both conditions, we can start with the number 126,000,000,000, which has three factors of 2 and is divisible by 3. To make it not divisible by 9, we can add 43, which is a prime number and has a sum of digits that is a multiple of 3. This gives us the number 126,000,000,043, which is not divisible by 9.
To make it divisible by 4 but not by 8, we can add 216, which is 2³ × 3³. This gives us the number 126,000,000,259, which is divisible by 4 but not by 8. To make it divisible by 3 but not by 9, we can add 2,000, which is 2³ × 5³. This gives us the final number of 126,000,004,259, which is divisible by 3 but not by 9 and also by 4 but not by 8.

We have shown that if the statement holds for k, then it also holds for k + 1.

To prove the statement using mathematical induction, we will first show that it holds true for the base case (n = 1), and then we will assume that it holds for an arbitrary natural number k and prove that it holds for k + 1.

Base Case (n = 1):

When n = 1, we have:

1(1+1)(2(1)+1) = 6

And the sum of squares on the right side is:

1² = 1

Since both sides of the equation are equal to 6, the base case holds.

Inductive Hypothesis:

Assume that the statement holds for some arbitrary natural number k. In other words, assume that:

k(k+1)(2k+1) = 1² + 2² + ... + k² ----(1)

Inductive Step:

We need to show that the statement also holds for k + 1. That is, we need to prove that:

(k+1)((k+1)+1)(2(k+1)+1) = 1² + 2² + ... + k² + (k+1)² ----(2)

Starting with the left-hand side of equation (2):

(k+1)((k+1)+1)(2(k+1)+1)

= (k+1)(k+2)(2k+3)

= (k(k+1)(2k+1)) + (3k(k+1)) + (2k+3)

Now, substituting equation (1) into the first term, we get:

(k(k+1)(2k+1)) = 1² + 2² + ... + k²

Expanding the second term (3k(k+1)) and simplifying, we have:

3k(k+1) = 3k² + 3k

Combining the terms (2k+3) and (3k² + 3k), we get:

2k+3 + 3k² + 3k = 3k² + 5k + 3

Now, we can rewrite equation (2) as:

3k² + 5k + 3 + 1² + 2² + ... + k²

Since we assumed equation (1) to be true for k, we can replace it in the above equation:

= 1² + 2² + ... + k² + (k+1)²

Thus, we have shown that if the statement holds for k, then it also holds for k + 1. By the principle of mathematical induction, we conclude that the statement holds for all natural numbers n.

The equation 2sinθ - √2 = 0 can be solved for θ by finding the inverse of the sine function and using trigonometric identities. The solutions are θ = π/4 and θ = 5π/4.

To solve the equation 2sinθ - √2 = 0, we can isolate the sine term by moving the constant √2 to the other side of the equation:

2sinθ = √2

Next, we divide both sides of the equation by 2 to isolate sinθ:

sinθ = √2/2

This indicates that θ is an angle whose sine value is equal to √2/2. We can determine the values of θ by referring to the unit circle or using trigonometric values of common angles.

The sine value √2/2 corresponds to two angles: π/4 and 5π/4. These angles satisfy the equation sinθ = √2/2, and they fall within the interval 0 ≤ θ < 2π.

Therefore, the solutions to the equation 2sinθ - √2 = 0 are θ = π/4 and θ = 5π/4.

The first three nonzero terms in the Taylor polynomial approximation for the given initial value problem are: 1 - t^2/8 + t^4/128.

Given the initial value problem: x′′ + 8tx = 0; x(0) = 1, x′(0) = 0. To find the first three nonzero terms in the Taylor polynomial approximation, we follow these steps:

Step 1: Find x(t) and x′(t) using the integrating factor.

We start with the differential equation x′′ + 8tx = 0. Taking the integrating factor as I.F = e^∫8t dt = e^4t, we multiply it on both sides of the equation to get e^4tx′′ + 8te^4tx = 0. This simplifies to e^4tx′′ + d/dt(e^4tx') = 0.

Integrating both sides gives us ∫ e^4tx′′ dt + ∫ d/dt(e^4tx') dt = c1. Now, we have e^4tx' = c2. Differentiating both sides with respect to t, we get 4e^4tx' + e^4tx′′ = 0. Substituting the value of e^4tx′′ in the previous equation, we have -4e^4tx' + d/dt(e^4tx') = 0.

Simplifying further, we get -4x′ + x″ = 0, which leads to x(t) = c3e^(4t) + c4.

Step 2: Determine the values of c3 and c4 using the initial conditions.

Using the initial conditions x(0) = 1 and x′(0) = 0, we can substitute these values into the expression for x(t). This gives us c3 = 1 and c4 = -1/4.

Step 3: Write the Taylor polynomial approximation.

The Taylor approximation to three nonzero terms is x(t) = 1 - t^2/8 + t^4/128 + ...

Therefore, the starting value problem's Taylor polynomial approximation's first three nonzero terms are: 1 - t^2/8 + t^4/128.

The equation of the line passing through the point (5,-3) and perpendicular to the line passing through the points (-1,1) and (-2,2) is y = x - 8.

To find the equation of the line passing through the point (5,-3) and perpendicular to the line passing through the points (-1,1) and (-2,2), we follow these steps:

Step 1: Find the slope of the line passing through (-1,1) and (-2,2).

Using the slope formula, we have:

m = (y2 - y1) / (x2 - x1),

where (x1, y1) = (-1, 1) and (x2, y2) = (-2, 2).

Plugging in the values, we get:

m = (2 - 1) / (-2 - (-1)) = -1.

Step 2: Find the slope of the line perpendicular to the line passing through (-1,1) and (-2,2).

Perpendicular lines have negative reciprocal slopes. Therefore, the slope of the line perpendicular to the line passing through (-1,1) and (-2,2) is the negative reciprocal of -1.

i.e. m' = -1/m' = -1/-1 = 1.

Step 3: Find the equation of the line passing through (5,-3) with slope 1.

We have the slope (m') of the line passing through (5,-3), and we also have a point (5,-3) on the line. We can use the point-slope form of the equation of a line to find the equation of the line passing through (5,-3) and perpendicular to the line passing through (-1,1) and (-2,2).

Point-slope form: y - y1 = m'(x - x1),

where (x1, y1) = (5,-3) and m' = 1.

Plugging in the values, we get:

y - (-3) = 1(x - 5),

y + 3 = x - 5,

y = x - 5 - 3,

y = x - 8.

Thus,y = x - 8 is the equation of the line travelling through the point (5,-3) and perpendicular to the line going through the points (-1,1) and (-2,2).
