PEMDAS is an acronym used to remember the order of operations in arithmetic and algebraic expressions. It stands for:

Parentheses: Simplify expressions inside parentheses first.

Exponents: Simplify any expressions involving exponents or powers.

Multiplication and Division: Perform multiplication and division in order from left to right.

Addition and Subtraction: Perform addition and subtraction in order from left to right.

Now,

(|-52 + 1| (-1) + 4²) / (-84 ÷ 7 + 5)

We solve | | first and exponents second.

|-52 + 1| = |-51| = 51

4² = 16

And,

-84 ÷ 7 = -84/7 = -12

So,

(|-52 + 1| (-1) + 4²) / (-84 ÷ 7 + 5)

= 51 x -1 + 16 / -12 + 5

= -51 + 16 / -12 + 5

that the solution is only valid for |x| < 1, since the differential equation is singular at x = ±1.

We can solve the given differential equation using the Frobenius method, by assuming that the solution can be represented as a power series:

y(x) = ∑(n=0)^(∞) a_n x^n

Differentiating the series twice, we get:

y'(x) = ∑(n=1)^(∞) n a_n x^(n-1)

y''(x) = ∑(n=2)^(∞) n(n-1) a_n x^(n-2)

Substituting these into the differential equation, we get:

(1-x^2) ∑(n=2)^(∞) n(n-1) a_n x^(n-2) - 2x ∑(n=1)^(∞) n a_n x^(n-1) + 2 ∑(n=0)^(∞) a_n x^n = 0

Simplifying and shifting the indices, we get:

∑(n=0)^(∞) [(n+2)(n+1) a_{n+2} - 2n a_n + 2a_n] x^n = 0

This gives us the following recurrence relation for the coefficients:

(n+2)(n+1) a_{n+2} = 2n a_n - 2a_n

Simplifying further, we get:

a_{n+2} = - (2n/(n+2)(n+1)) a_n

Starting with n = 0, we can compute the coefficients a_n in terms of a_0:

a_2 = - 2/3 a_0

a_4 = 2/15 a_2 = - 4/45 a_0

a_6 = - 2/21 a_4 = 8/315 a_0

a_8 = 2/99 a_6 = - 16/3465 a_0

1. The instantaneous rate of change in the amount after 2 years is [tex]$1,605.64[/tex] per year

2. The instantaneous rate of change in the amount at the time the amount is equal to [tex]$14,101[/tex] is approximately $994.78 per year

[tex]A = P[/tex]× [tex]e^{rt}[/tex]

where P is the principal (initial investment), r is the annual interest rate as a decimal, and t is the time in years.

For this problem, we have P = $10,000, r = 0.067 (6.7% as a decimal), and we want to find the instantaneous rate of change in the amount after 2 years, so t = 2.

Part 1:

To find the instantaneous rate of change, we need to take the derivative of the function A(t) with respect to t:

[tex]dA/dt = Pre^{rt}[/tex]

At[tex]t = 2[/tex], we have:

[tex]A(2) = $10,000e^{0.0672}[/tex]

[tex]= $11,868.94[/tex]

[tex]dA/dt = $10,0000.067e^{0.067}[/tex]×[tex]2)[/tex]

[tex]= $1,605.64[/tex]

So the instantaneous rate of change in the amount after 2 years is $1,605.64 per year

Part 2:

To find the time at which the amount in the account is $14,101, we need to solve the equation A = $14,101 for t:

[tex]$14,101[/tex][tex]= $10,000[/tex] × [tex]e^{0.067t}[/tex]

Dividing both sides by $10,000:

[tex]1.4101 = e^{0.067t}[/tex]

Taking the natural logarithm of both sides:

[tex]ln(1.4101) = 0.067t[/tex]

Solving for t:

[tex]t = ln(1.4101)/0.067[/tex]

≈ [tex]3.5 years[/tex]

So the time at which the amount in the account is $14,101 is approximately 3.5 years.

To find the instantaneous rate of change at this time, we need to evaluate the derivative at t = 3.5:

[tex]dA/dt = $10,0000.067e^{0.067}[/tex]×[tex]3.5)[/tex]

≈ [tex]$994.78[/tex]

So the instantaneous rate of change in the amount at the time the amount is equal to $14,101 is approximately $994.78 per year

Compound interest is the interest you earn on interest. This can be illustrated by using basic math: if you have $100 and it earns 5% interest each year, you'll have $105 at the end of the first year. At the end of the second year, you'll have $110.25

Step-by-step explanation:

The exact values of the cosecant, secant, and cotangent ratios of -7pi/4 radians are -√(2), -√(2), and 1.

Here are the exact values of the cosecant, secant, and cotangent ratios of -7π/4 radians:

The cosecant of an angle is equal to the length of the hypotenuse of a right triangle with that angle as its opposite side, divided by the length of the opposite side. The formula for cosecant is cosec(θ) = 1/sin(θ).

In this case, the sine of -7π/4 radians is -√(2)/2, so the cosecant is -2/√(2), which simplifies to -√(2).

The secant of an angle is equal to the length of the hypotenuse of a right triangle with that angle as its adjacent side, divided by the length of the adjacent side. The formula for secant is sec(θ) = 1/cos(θ).

In this case, the cosine of -7π/4 radians is -√(2)/2, so the secant is -2/√(2), which simplifies to -√(2).

The cotangent of an angle is equal to the length of the adjacent side of a right triangle with that angle as its opposite side, divided by the length of the opposite side.

The formula for cotangent is cot(θ) = 1/tan(θ). In this case, the tangent of -7π/4 radians is 1, so the cotangent is 1.

The center of mass of the thin parabola plate is located at the point (1/2, 3/10).

The center of mass of a two-dimensional object is the point (X', Y') where the object would balance if it were suspended from that point. The coordinates X' and Y' are given by the formulas:

X' = Mx / M

Y' = My / M

where M is the total mass of the object, Mx is the moment of the object with respect to the x-axis, and My is the moment of the object with respect to the y-axis. The moments are defined as integrals of the density over the region:

Mx = ∫∫ xρ(x,y) dA

My = ∫∫ yρ(x,y) dA

where ρ(x,y) is the density of the object at the point (x,y) and dA is an element of area.

In this case, the density of the thin plate is constant, so we can take it out of the integrals:

Mx = ∫∫ x dA = ∫∫ x dx dy

My = ∫∫ y dA = ∫∫ y dx dy

The region bounded by the parabola y = x² and the line y = 0 can be described as the set of points (x,y) such that 0 ≤ y ≤ x². Therefore, we can set up the integrals as follows:

Mx = ∫∫ x dx dy = ∫0^1 ∫0ˣ x dx dy = ∫0^1 (1/2)x² dy = 1/6

My = ∫∫ y dx dy = ∫0^1 ∫0ˣ y dx dy = ∫0^1 (1/2)x⁴ dy = 1/10

where we have used the fact that the total mass of the plate is equal to the area of the region, which is 1/3.

Finally, we can use these values to compute the coordinates of the center of mass:

X' = Mx / M = (1/6) / (1/3) = 1/2

Y' = My / M = (1/10) / (1/3) = 3/10

Therefore, the center of mass of the thin plate is located at the point (1/2, 3/10).

c) The solution to the initial-value problem is: xr - ye^y = z ln|x| + 1.

(a) We can start by separating the variables and integrating both sides with respect to x and y:
xy^2 dy = y^3 - r^3 dx
Integrating both sides:
(1/3) y^3 = xr^3/3 + C
Using the initial condition y(2) = 2:
(1/3) (2)^3 = 2r^3/3 + C
C = 2/3
Thus, the solution to the initial-value problem is:
y^3 = 3xr^3 + 2

(b) Similar to part (a), we can separate the variables and integrate both sides with respect to x and y:
x^2 + 2y^2 dy = ry dx
Integrating both sides:
x^2 y + (1/2) y^3 = (1/2) r^2 + C
Using the initial condition y(-1) = 1:
(-1)^2 (1) + (1/2) (1)^3 = (1/2) r^2 + C
C = 3/2
Thus, the solution to the initial-value problem is:
x^2 y + (1/2) y^3 = (1/2) r^2 + 3/2

(c) We can start by multiplying both sides by dx and integrating:
(x-yey) dr = zey dy/x
Integrating both sides:
xr - ye^y = z ln|x| + C
Using the initial condition y(1) = 0:
1r - 0e^0 = z ln|1| + C
C = 1

(c) Assuming the same noteworthiness level of 0.1, ready to utilize a control calculator or program to discover that a test measure of around 22 is required to attain a control of at slightest 0.8.

(a) To test in case the standard deviation of gap distance across surpasses 0.01 millimeters, we are able utilize a one-tailed t-test with a noteworthiness level of 0.1. The invalid speculation is that the standard deviation is less than or rise to to 0.01 millimeters, and the elective theory is that the standard deviation is more noteworthy than 0.01 millimeters. We expect that the basic dispersion of the gap breadths is around ordinary.

Utilizing the equation for the t-test, we get:

[tex]t = (0.008 / \sqrt{} (14)) / (0.01)[/tex]

t = 2.26

The degrees of opportunity for this test is n-1 = 14. From a t-distribution table, we discover that the p-value for a one-tailed test with 14 degrees of opportunity and t=2.26 is roughly 0.021. Since the p-value is less than the noteworthiness level of 0.1, we dismiss the invalid speculation.

(b) To discover the likelihood that the test in part (a) will identify a 50% increment in standard deviation, we have to be calculate the control of the test. The control of a test is the likelihood of dismissing the invalid theory when the elective theory is genuine.

The control of the test depends on a few components, counting the test measure, the noteworthiness level, and the impact measure. In this case, the effect size is the contrast between the actual standard deviation and the hypothesized esteem, communicated in standard deviation units.

(c) If the real standard deviation is 0.0125 millimeters and we need to distinguish this with a control of at least 0.8, we ought to decide the test measure required for the test. Assuming the same noteworthiness level of 0.1, ready to utilize a control calculator or program to discover that a test measure of around 22 is required to attain a control of at slightest 0.8.

We have utilized a one-tailed t-test to decide that there's solid prove to show that the standard deviation of gap breadth surpasses 0.01 millimeters.

We can conclude that for all integers a and b, if a|b, then a ≤ b.

To prove that for all m and n, if m ≠ n, then m+n ≠ Q, we will use proof by contradiction.

Assume that for some m and n, m ≠ n, and m+n = Q, where Q is a rational number. By the definition of a rational number, Q can be expressed as the ratio of two integers, p and q, where q ≠ 0.

Thus, we have:

m + n = p/q

Multiplying both sides by q, we get:

mq + nq = p

Rearranging, we get:

mq = p - nq

Since p, n, and q are integers, p - nq is also an integer. Therefore, mq is an integer.

But we know that m and n are integers and m ≠ n, which implies that m and n have different prime factorizations. Therefore, mq cannot be an integer, as it would require m and q to have a common factor, which is not possible.

This contradicts our assumption that m+n = Q, and hence, we can conclude that for all m and n, if m ≠ n, then m+n ≠ Q.

To prove that for all integers a and b, if a|b, then a ≤ b, we will use direct proof.

Assume that a and b are integers such that a|b, i.e., there exists an integer k such that b = ak.

To prove that a ≤ b, we need to show that a is less than or equal to k times a, i.e., a ≤ ka.

Dividing both sides of the equation b = ak by a (which is possible as a ≠ 0 since it is a divisor of b), we get:

b/a = k

Since k is an integer, we know that b/a is also an integer. Therefore, a must be less than or equal to b/a.

Multiplying both sides of the inequality a ≤ b/a by a (which is a positive number since a > 0), we get:

[tex]a^2 ≤ ab[/tex]

Since a and b are both positive integers, we know that [tex]a^2 ≤[/tex] ab implies that [tex]a ≤ b[/tex].

Therefore, we can conclude that for all integers a and b, if a|b, then a ≤ b.

Determine the interest payments for these three bonds. Here's a step-by-step explanation for each bond:

a. 3.80% coupon corporate bond (paid semiannually):
1. Convert the annual coupon rate to a semiannual rate: 3.80% / 2 = 1.90%
2. Calculate the interest payment: $1,000 (par value) * 1.90% (semiannual rate) = $19.00

The semiannual interest payment for the 3.80% coupon corporate bond is $19.00.

b. 4.55% coupon Treasury note:
1. As Treasury notes typically pay interest semiannually, we'll convert the annual coupon rate to a semiannual rate: 4.55% / 2 = 2.275%
2. Calculate the interest payment: $1,000 (par value) * 2.275% (semiannual rate) = $22.75

The semiannual interest payment for the 4.55% coupon Treasury note is $22.75.

c. Corporate zero coupon bond maturing in ten years:
Zero coupon bonds do not pay periodic interest. Instead, they are sold at a discount to their par value and mature at their full par value. In this case, there's no interest payment to calculate, as the bondholder will receive the $1,000 par value at the end of the ten-year maturity period.

Answer: 2xy

Step-by-step explanation:

you need the biggest factor that goes into

If the corners of the kitchen are (8, 4), (−3, 4), (8, −8), and (−3, −8), the area of the kitchen is 132 square feet. So, the correct option is C.

To find the area of the rectangular kitchen, we need to use the formula for the area of a rectangle, which is A = L x W, where A is the area, L is the length, and W is the width.

From the given ordered pairs, we can determine the length and width of the rectangle. The length is the distance between the points (8,4) and (-3,4), which is 8 - (-3) = 11 feet. The width is the distance between the points (8,4) and (8,-8), which is 4 - (-8) = 12 feet.

Now that we know the length and width, we can find the area by multiplying them together:

A = L x W = 11 x 12 = 132 square feet

Therefore, the correct answer is C.

The area of the parallelogram formed by the given vertices A(1, 0, -1), B(1, 7, 2), C(2, 4, -1), and D(0, 3, 2) is 2√21 square units.

To calculate the area of a parallelogram, we can use the cross product of two vectors formed by the sides of the parallelogram. The vectors AB and AD can be calculated by subtracting the coordinates of the initial and final points.

The cross product of these vectors gives us a vector representing the area of the parallelogram. Taking the magnitude of this vector gives us the area of the parallelogram. The magnitude of the cross product of AB and AD is 24, so the area of the parallelogram is 24 square units.

In this case, the vector AB is (-3, 7, 3), and the vector AD is (-1, 3, 3). Taking the cross product of these vectors gives us the vector (-12, 6, 24). The magnitude of this vector is √(12² + 6² + 24²) = √756 = 2√21. Therefore, the area of the parallelogram is 2√21 square units.

The alternating series test can be used to show convergence of the alternating series I, II, and III given in the options and the correct answer to this question is Option A. I only.

The alternating series test is a method used to determine the convergence or divergence of alternating series. According to the alternating series test, an alternating series converges if the absolute value of its terms decreases monotonically to zero. In other words, if the absolute value of the terms in an alternating series eventually becomes smaller and smaller until it is less than or equal to a certain positive number, then the series converges.

In conclusion, the alternating series test can be used to show the convergence of series I and III, but not for series II. Therefore, the answer is (A) I only.

Declan's reasoning does make sense. This is because 3/4 and 1/2 have the same denominator, and 3/4 is a larger fraction than 1/2.

Therefore, it is reasonable to assume that 3/4 is greater than 6/12 because 6/12 simplifies to 1/2. Simplifying fractions means dividing the numerator and denominator by the same number, in this case, 6 is divisible by 2, so we can reduce the fraction to 1/2.

So, Declan is correct in his reasoning that 3/4 is greater than 6/12. It is important to understand the relationship between fractions and their denominators to make such comparisons accurately.

3/4 = 9/12

1/2 = 6/12

6/12 = 6/12

Since 9/12 (which is equivalent to 3/4) is greater than 6/12 (which is equivalent to 1/2), we can say that 3/4 is indeed greater than 6/12.

Therefore, Declan's reasoning is correct.

we can say with 95% confidence that the proportion of all consumers who prefer to purchase domestic automobiles is between 0.354 and 0.446.

To develop a 95% confidence interval for the proportion of all consumers who prefer to purchase domestic automobiles, we can use the formula:

CI = p ± z*(√(p*(1-p)/n))

where:

p = proportion of consumers who prefer domestic automobiles = 240/600 = 0.4
n = sample size = 600
z = z-score for 95% confidence level = 1.96

Plugging in the values, we get:

CI = 0.4 ± 1.96*(√(0.4*(1-0.4)/600))
  = 0.4 ± 0.046
  = (0.354, 0.446)
