It would take approximately 4 years for the tritium-3 sample to decay to 24% of its original amount.

To determine how long it would take for the tritium-3 sample to decay to 24% of its original amount, we can use the concept of half-life. The half-life of tritium-3 is approximately 12.3 years.

Given that the sample decayed to 84% of its original amount after 4 years, we can calculate the number of half-lives that have passed:

(100% - 84%) / 100% = 0.16

To find the number of half-lives, we can use the formula:

Number of half-lives = (time elapsed) / (half-life)

Number of half-lives = 4 years / 12.3 years ≈ 0.325

Now, we need to find how long it takes for the sample to decay to 24% of its original amount. Let's represent this time as "t" years.

Using the formula for the number of half-lives:

0.325 = t / 12.3

Solving for "t":

t = 0.325 * 12.3
t ≈ 3.9975

Therefore, it would take approximately 4 years for the tritium-3 sample to decay to 24% of its original amount.

(-4 + 7i)² = 9 + 56i ; Where x + iy is complex form.

To find the square of (-4 + 7i), we can use the formula for squaring a complex number, which states that (a + bi)² = a² + 2abi - b².

In this case, a = -4 and b = 7. Applying the formula, we have:

(-4 + 7i)² = (-4)² + 2(-4)(7i) - (7i)²

= 16 - 56i - 49i²

Since i² is equal to -1, we can substitute -1 for i²:

(-4 + 7i)² = 16 - 56i - 49(-1)

= 16 - 56i + 49

= 65 - 56i

So, (-4 + 7i)² simplifies to 65 - 56i.

If we multiply the result by 4, we get:

4(-4 + 7i)² = 4(65 - 56i)

= 260 - 224i

Therefore, 4(-4 + 7i)² is equal to 260 - 224i.

The square of (-4 + 7i) is 65 - 56i. Multiplying that result by 4 gives us 260 - 224i.

The maximum error in the surface area is 23.36 square centimeters, and the relative error is 3.3%.

The given problem deals with estimating the maximum error in the calculated surface area of a sphere based on the measured circumference and its possible error. Here are the steps to solve the problem:

1. The surface area of a sphere is given by the formula: S = 4πr^2.

2. Differentiating the surface area formula with respect to r gives: dS/dr = 8πr.

3. The maximum error in the circumference is given as 0.50000 cm. To find the maximum error in the radius, we use the formula: Δr/r = ΔC/(2πr), where ΔC is the error in circumference.

4. Substituting the given values into the formula, we have: Δr/r = (0.50000)/(2πr).

5. We can calculate r using the measured circumference: r = (circumference)/(2π) = 74.000/(2π) = 11.785 cm.

6. Substituting the value of r into the formula, we can find Δr: Δr = (0.50000 × 11.785)/(2π) = 0.0937 cm.

7. To calculate the maximum error in the surface area, we use the formula: ES ≈ |(dS/dr) × Δr|.

8. Substituting the values into the formula, we have: ES ≈ |(8πr) × 0.0937| = 23.36.

9. Therefore, the maximum error in the calculated surface area is 23.36 square centimeters.

10. The relative error in the calculated surface area can be calculated as the ratio of the maximum error to the actual surface area: Relative error = ES/S.

11. Substituting the values, we get: Relative error = 23.36/(4π × 11.785^2).

12. Evaluating the expression, the relative error in the calculated surface area is approximately 0.033 or 3.3%.

Thus, the maximum error in the surface area is 23.36 square centimeters, and the relative error is 3.3%.

The expression (rad ob ) denotes the measure of an angle in radians that is greater than 90 degrees but less than 180 degrees. For instance, pi/2 is an angle in radians equal to 90 degrees. When you double the value of pi/2, you get pi radians, which is equal to 180 degrees. cwWhen writing cw, you are referring to a clockwise rotation of an object.

So, in summary, cw means "clockwise."(rad ob ) × cw Now that you understand the terms rad ob and cw, let's combine them and examine whether their product is possible or not. Since (rad ob ) refers to an angle's measurement in radians, the product of (rad ob ) × cw does not exist.

The rate of change of tanθ is 1/3 per minute when the bottom of the ladder is 24 feet from the wall.

Let's denote the length of the ladder as L, the distance of point B from the wall as x, and the angle between the ladder and the ground as θ.

We have a right triangle formed by the ladder, the ground, and the wall. The opposite side of the triangle is x, and the adjacent side is L. Therefore, tanθ = x/L.

We are given that the bottom end of the ladder is sliding away from the wall at a rate of 6 feet per minute, which means dx/dt = 6 ft/min.

To find the rate of change of tanθ, we need to differentiate the equation tanθ = x/L with respect to time t. Using implicit differentiation, we have:

sec^2θ * dθ/dt = (d/dt)(x/L)

Since L is a constant (the length of the ladder is fixed), we can rewrite the equation as:

sec^2θ * dθ/dt = (1/L) * (dx/dt)

We know that dx/dt = 6 ft/min and L = 25 ft (given). Plugging these values into the equation, we have:

sec^2θ * dθ/dt = (1/25) * 6

Simplifying, we get:

dθ/dt = (6/25) * cos^2θ

To find the rate of change of tanθ when x = 24 ft, we substitute this value into the equation:

dθ/dt = (6/25) * cos^2θ

Since tanθ = x/L, when x = 24 ft, we can find cosθ by using the Pythagorean theorem:

cosθ = sqrt(L^2 - x^2)/L

       = sqrt(25^2 - 24^2)/25

       = 7/25

Substituting this value into the equation, we have:

dθ/dt = (6/25) * (7/25)^2

        = (6/25) * 49/625

        = 294/15625

        = 1/53

Therefore, the rate of change of tanθ is 1/53 per minute when the bottom of the ladder is 24 feet from the wall.

The limit as x approaches -3 of the function (x² + 13x + 30)/(x + 3) exists and equals 10.

To find the limit of a function as x approaches a specific value, we substitute that value into the function and see if it converges to a finite number. In this case, we substitute -3 into the function:

limx→-3 (x² + 13x + 30)/(x + 3)

Plugging in -3, we get:

(-3)² + 13(-3) + 30 / (-3 + 3)

= 9 - 39 + 30 / 0

The denominator is zero, which indicates a potential issue. To determine the limit, we can simplify the expression by factoring the numerator:

(x² + 13x + 30) = (x + 10)(x + 3)

We can cancel out the common factor (x + 3) in both the numerator and denominator:

limx→-3 (x + 10)(x + 3)/(x + 3)

= limx→-3 (x + 10)

Now we can substitute -3 into the simplified expression:    

(-3 + 10)

The quotient rule states that for a function f(x) = g(x) / h(x), the derivative f'(x) is given by f'(x) = [g'(x)h(x) - g(x)h'(x)] / [h(x)]².

In this case, g(x) = (x + 6) and h(x) = (x - 6)⁵.

Taking the derivatives, we have:

g'(x) = 1 (the derivative of x + 6 is 1)

h'(x) = 5(x - 6)⁴ (using the power rule)

Now we can apply the quotient rule:

f'(x) = [(x - 6)(1) - (x + 6)(5(x - 6)⁴)] / [(x - 6)⁵]²

It is incorrect to say that the sum of a rational and an irrational number is always irrational (A) or always rational (B). Similarly, it is incorrect to say that the sum is never irrational (C). The correct statement is that the sum of a rational and irrational number is sometimes a rational number (D).

The correct answer is D. The sum of a rational and irrational number is sometimes a rational number.

To understand why, let's consider an example. Let's say we have a rational number, such as 2/3, and an irrational number, such as √2.

When we add these two numbers together: 2/3 + √2

The result is a sum that can be rational or irrational depending on the specific numbers involved. In this case, the sum is approximately 2.94, which is an irrational number. However, if we were to choose a different irrational number, the result could be rational.

For instance, if we had chosen π (pi) as the irrational number, the sum would be:2/3 + π

In this case, the sum is an irrational number, as π is irrational. However, it's important to note that there are cases where the sum of a rational and an irrational number can indeed be rational, such as 2/3 + √4, which equals 2.

Zorch would need to exert the opposing force for approximately 1.15 years to slow Earth's rotation to once per 35.0 hours.

To determine the time required for Zorch to accomplish his goal, we can follow the steps in the Problem-Solving Strategy for Rotational Dynamics:

Step 1: Identify what is given and what is asked for.

Given:

Force exerted by Zorch: 3.70×10^7 N

Desired period of Earth's rotation: 35.0 hours

Asked for:

Time Zorch must push with this force

Step 2: Identify the principle(s) or equation(s) needed to solve the problem.

The principle of rotational dynamics that we can use is:

Torque (τ) = Inertia (I) × Angular Acceleration (α)

Step 3: Set up the problem.

Zorch wants to slow down Earth's rotation, which means he wants to decrease its angular velocity. To do this, he needs to exert a torque in the opposite direction of Earth's rotation. The torque required can be calculated as:

τ = I × α

Step 4: Solve the problem.

The inertia (I) of Earth can be approximated as I = 0.330 × 10^38 kg·m² (a known value).

The angular acceleration (α) can be calculated using the equation:

α = Δω / Δt

Since Zorch wants to slow Earth's rotation to once per 35.0 hours, the change in angular velocity (Δω) is given by:

Δω = 2π / (35.0 hours)

Now, we can rearrange the equation τ = I × α to solve for time (Δt):

Δt = τ / (I × α)

Substituting the given values, we get:

Δt = (3.70×10^7 N) / (0.330 × 10^38 kg·m² × (2π / (35.0 hours)))

Evaluating this expression will give us the time required for Zorch to push with the given force. The result is approximately 1.15 years.

Therefore, Zorch must exert the opposing force for approximately 1.15 years to slow Earth's rotation to once per 35.0 hours.

The position of the particle at time t = 4 is 173. To find the position of the particle at time t = 4, we can integrate the acceleration function to obtain the velocity function.

Then integrate the velocity function to obtain the position function.

Given that the acceleration is a(t) = 6t + 4, we can integrate it to find the velocity function v(t):

∫ a(t) dt = ∫ (6t + 4) dt

v(t) = 3t^2 + 4t + C

We are also given that the velocity at time t = 0 is v(0) = 16. Substituting this into the velocity function, we can solve for the constant C:

v(0) = 3(0)^2 + 4(0) + C

16 = C

So the velocity function becomes:

v(t) = 3t^2 + 4t + 16

Next, we integrate the velocity function to find the position function s(t):

∫ v(t) dt = ∫ (3t^2 + 4t + 16) dt

s(t) = t^3 + 2t^2 + 16t + D

We are given that the position at time t = 0 is s(0) = 13. Substituting this into the position function, we can solve for the constant D:

s(0) = (0)^3 + 2(0)^2 + 16(0) + D

13 = D

So the position function becomes:

s(t) = t^3 + 2t^2 + 16t + 13

To find the position at time t = 4, we substitute t = 4 into the position function:

s(4) = (4)^3 + 2(4)^2 + 16(4) + 13

s(4) = 64 + 32 + 64 + 13

s(4) = 173

a. The equation without the parameter is given by x = 3cos(t), y = -3sin(t), and z = t. b. When t = 0, the graph represents the initial point of the curve, which is (3, 0, 0).

a. Without the parameter, the equation becomes x = 3cos(t), y = -3sin(t), and z = t. This describes a curve in three-dimensional space.

b. When t = 0, the equation becomes x = 3cos(0) = 3, y = -3sin(0) = 0, and z = 0. This corresponds to the point (3, 0, 0). Therefore, the graph when t = 0 is a single point located at (3, 0, 0).

c. When 0 < t ≤ 3π, the equations describe a helix-like curve. As t increases, the curve extends along the positive z-axis while simultaneously rotating in the xy-plane due to the sinusoidal nature of the x and y coordinates. The curve spirals around the z-axis with each turn in the xy-plane.

d. The difference between parts b and c is that in part b, we only consider the specific point when t = 0, resulting in a single point. In part c, we consider a range of values for t, which allows us to visualize the entire curve traced by the parameter over the interval 0 < t ≤ 3π. Part c provides a more comprehensive representation of the curve compared to part b, which only shows a single point.

The first derivative of the function [tex]g(x) = 6x^3 + 45x^2 + 72x[/tex]is [tex]g'(x) = 18x^2 + 90x + 72[/tex], which is determined by applying the power rule and constant multiple rule of differentiation.

To find the first derivative, we apply the power rule and constant multiple rule of differentiation. The power rule states that if we have a term of the form[tex]x^n[/tex], the derivative is [tex]nx^(n-1)[/tex].

In this case, we have three terms: [tex]6x^3[/tex], [tex]45x^2[/tex], and 72x. Applying the power rule to each term, we get:

- The derivative of [tex]6x^3 is (3)(6)x^(3-1) = 18x^2[/tex].

- The derivative of [tex]45x^2 is (2)(45)x^(2-1) = 90x[/tex].

- The derivative of [tex]72x is (1)(72)x^(1-1) = 72[/tex].

Combining these derivatives, we obtain the first derivative of g(x):

[tex]g'(x) = 18x^2 + 90x + 72.[/tex]

This derivative represents the rate of change of the function g(x) with respect to x. It gives us information about the slope of the tangent line to the graph of g(x) at any point.

The expression for the variance of a time series variable [tex]\(y_t\)[/tex] can be obtained using the mean and squared deviations from the mean. The variance measures the average squared deviation of the variable from its mean, providing an indication of its variability.

To obtain the expression for the variance of [tex]\(y_t\)[/tex], we first calculate the mean of the variable, denoted as [tex]\(\mu\)[/tex]. Next, we calculate the squared deviations of each data point from the mean, denoted as [tex]\((y_t - \mu)^2\)[/tex]. These squared deviations quantify the variability of the variable around its mean.

The variance, denoted as [tex]\(Var(y_t)\)[/tex], is given by the formula:

[tex]\[ Var(y_t) = \frac{1}{N} \sum_{t=1}^{N} (y_t - \mu)^2 \][/tex]

This expression represents the average of the squared deviations, providing a measure of the variability or spread of the variable [tex]\(y_t\)[/tex]. A higher variance indicates greater variability, while a lower variance indicates less variability around the mean. It is commonly used in statistical analysis to assess the dispersion of a dataset and is an important parameter in various statistical models and calculations.

The profit from the sale of x units of radiators for generators is given by P(x,y) = - x^2 – y^2 + 8x + 2y. The values of x and y that lead to a maximum profit are x = 1 and y = 4.

To find the values of x and y that lead to a maximum profit, we need to maximize the profit function P(x, y) = -x^2 - y^2 + 8x + 2y subject to the constraint x + y = 5 (the firm must produce a total of 5 units of radiators).

To solve this problem, we can use the method of Lagrange multipliers. The Lagrangian function is defined as:

L(x, y, λ) = -x^2 - y^2 + 8x + 2y + λ(x + y - 5)

Now, we need to find the critical points by solving the following system of equations:

1. ∂L/∂x = -2x + 8 + λ = 0

2. ∂L/∂y = -2y + 2 + λ = 0

3. ∂L/∂λ = x + y - 5 = 0

Solving equations 1 and 2 simultaneously, we have:

-2x + 8 + λ = 0     --> equation (4)

-2y + 2 + λ = 0     --> equation (5)

Subtracting equation (5) from equation (4), we get:

-2x + 8 + λ - (-2y + 2 + λ) = 0

-2x + 2y + 6 = 0

x - y = -3        --> equation (6)

Now, we can solve equations (6) and (3) simultaneously to find the values of x and y:

x - y = -3         --> equation (6)

x + y = 5          --> equation (3)

Adding equations (6) and (3), we get:

2x = 2

x = 1

Substituting x = 1 into equation (3), we have:

1 + y = 5

y = 4

So, the values of x and y that lead to a maximum profit are x = 1 and y = 4.

The value of ∂z/∂t when s = 2 and t = 1 is equal to Ae^2 + Be^4. We need to determine the values of A and B such that A + B

To find ∂z/∂t, we substitute the given expressions for x and y into the function z = xln(x^2 + y^2 - e^4) - 75xy. After differentiation, we evaluate the expression at s = 2 and t = 1.

Substituting x = te^s and y = e^st into z, we obtain z = (te^s)ln((te^s)^2 + (e^st)^2 - e^4) - 75(te^s)(e^st).

Taking the partial derivative ∂z/∂t, we apply the chain rule and product rule, simplifying the expression to ∂z/∂t = e^s(3tln((te^s)^2 + (e^st)^2 - e^4) - 2e^4t - 75e^st).

When s = 2 and t = 1, we evaluate ∂z/∂t to obtain ∂z/∂t = e^2(3ln(e^4 + e^4 - e^4) - 2e^4 - 75e^2).

Comparing this with Ae^2 + Be^4, we find A = -75 and B = -2. Therefore, A + B = -75 + (-2) = -77.

Fourier transform of x(t) is X(co), then X(0) is equal to 1. The correct answer is (b)

To find X(0), we need to evaluate the Fourier transform of x(t) at the frequency ω = 0.

Given x(t) = 2δ(t-4) - δ(t-3), where δ(t) represents the Dirac delta function.

The Fourier transform of δ(t-a) is 1, and the Fourier transform of a constant times a function is equal to the constant times the Fourier transform of the function.

Using these properties, we can evaluate the Fourier transform of x(t):

X(ω) = 2F[δ(t-4)] - F[δ(t-3)]

Since the Fourier transform of δ(t-a) is 1, we have:

X(ω) = 2(1) - (1)

X(ω) = 1

Therefore, X(0) is equal to 1. The correct answer is (b) 1.

The given expressions indicate the presence of three modes: Cut off, Triode, or Saturation, without mentioning the "linear region." To determine the mode based on these expressions.

In electronic devices such as transistors, there are three major operating modes: Cut off, Triode (or active region), and Saturation. These modes define the behavior of the device under different voltage and current conditions.

The expressions provided (\(v_0 = v_s = 1\) and \(r\), \(V_2\), \(V_1\), \(V\), \(V_A\), \(V_S\), and \(i\)) likely correspond to specific parameters or variables associated with the different modes.

To determine the mode based on these expressions, it is necessary to compare the values or relationships between these variables against the defining characteristics of each mode.

In the Cut off mode, the device is effectively off, with no significant current flow. Therefore, if \(V\) or \(i\) is zero, the mode could be Cut off.

In the Triode mode, the device operates as an amplifier, and both the voltage and current values are significant and can vary. Without more specific information or relationships between the variables, it is challenging to determine the mode solely based on the given expressions.

In the Saturation mode, the device is fully on, with maximum current flow and typically saturated voltage values. If \(V\) or \(i\) reaches a maximum value, it may indicate the Saturation mode.

Overall, the expressions provided offer limited information, making it difficult to definitively identify the mode without further context or relationships between the variables.

The derivative of function f(x) = 490x is found as  f'(x) = 490.

The given function is f(x)=490x.

To differentiate the given function, we can use the Power Rule of differentiation.

The Power Rule of differentiation states that if

[tex]f(x) = x^n,[/tex]

then

[tex]f'(x) = nx^(n-1)[/tex]

The derivative of f(x) is given by:

f'(x) = d/dx(490x)

We can take the constant 490 outside of the differentiation as it is not a function of x, and we get:

f'(x) = 490 d/dx(x)

Using the Power Rule, we know that d/dx(x) = 1.

Hence, we have:

[tex]f'(x) = 490 x^0[/tex]

Therefore, the derivative of f(x) = 490x is : f'(x) = 490.

The parameterization is r = (1, 2, 3) + t(-1, 2, 2) + s(-2, 3, 2)where t and s are real parameters

To find the equation of a plane determined by three points, say, S, T, and U, use the cross product of two vectors formed by subtracting one of the points from the other two points.

Let's use the given points S(1, 2, 3), T(2, 0, 1), and U(3, -1, 1).

Step-by-step explanation for finding the equation of a plane determined by the three points S(1,2,3), T(2,0,1) and U(3,-1,1) are given below:

Find the direction vectors of two lines lying on the plane.

The direction vectors are formed by subtracting one point from the other two points.

We can use the vectors TS and US for this purpose.

Let's begin by finding the direction vector TS:

TS = S - T= (1 - 2)i + (2 - 0)j + (3 - 1)k= -i + 2j + 2k

Similarly, the direction vector US can be calculated as follows:

US = S - U= (1 - 3)i + (2 + 1)j + (3 - 1)k= -2i + 3j + 2k

Now we can find the normal vector by taking the cross product of the direction vectors TS and US:

n = TS x US= det i j k -1 2 2 -2 3 2= (4i - 6j + 5k) - (4i + 4j - 5k)i - (2i - 8j - 2k)j + (2i + 2j + 2k)k= -2i + 6j - 7k

Thus, the equation of the plane is:-

2x + 6y - 7z = d

To find the value of d, substitute one of the points, say S(1, 2, 3), into the equation of the plane:

2(1) + 6(2) - 7(3) = d-2 + 12 - 21 = d-11 = d

Therefore, the equation of the plane is:

2x + 6y - 7z = -11

Now, let's find a parameterization of this plane.

The vector equation of the plane is:

r = r0 + t1v1 + t2v2where r0 is a position vector, v1 and v2 are direction vectors of the plane, and t1 and t2 are real parameters.

The direction vectors of the plane are TS and US.

Let's use the point S(1, 2, 3) as the reference point, i.e., r0 = S:

r0 = (1, 2, 3)The parameterization is:

r = (1, 2, 3) + t(-1, 2, 2) + s(-2, 3, 2)where t and s are real parameters.
