Anissa's monthly mortgage payment will be $749.44.

The amount that the lender charges the borrower over and beyond the principal amount is referred to as the interest rate. A person who deposits money in a bank or other financial institution also gets additional income in terms of the recipient, known as interest, taking into account the time value of money.

In this case, we need to find the EMI - Equated Monthly Installments, Anissa has paid.

EMI = P*(1+r)^n / [(1+r)^n -1]

The Principal amount is P = $125,000.

The interest rate is, r = 6% p.a. = 0.005 per month.

The number of periods is, n = 30 × 12 = 360

The monthly payment is:

EMI = P*(1+r)^n / [(1+r)^n -1] = 3764.11/5.023 = 749.4381 = 749.44(approximately)

Thus, Anissa's monthly mortgage payment will be $749.44.

The inverse of the cube root function used to act for the situation in model is f⁻¹(x) = √x³ - 4

Inverse of the cube root function f(x)

f(x) = ∛ (x + 4) ²

To find the inverse function, let f(x) = y

So, y = ∛ (x + 4) ²

Taking the cube of both sides, we have

y³ = [∛ (x + 4) ²] ³

y³ = (x + 4) ²

Taking square root of both sides, we have

√y³ = √ (x + 4) ²

√y³ = (x + 4)

Subtracting 4 from both sides, we have

√y³ - 4 = x + 4 - 4

√y³ - 4 = x

change y with x, we have

√x³ - 4 = y

Replacing y with f⁻¹(x), we have

f⁻¹(x) = √x³ - 4

So, the inverse of the cube root function used to represent the situation in model is f⁻¹(x) = √x³ - 4

On average Shanth drinks 4.5 ounces of water in an hour.

Multiplication is the process of taking one integer and multiplying it by a certain number of times. 5 multiplied by 4 is 5 + 5 + 5 + 5 = 20. We took the number 5 and multiplied it by four. This is why multiplication is often known as "times".

When we multiply a four-digit multiplied by a two-digit multiplier, we multiply the multiplied with the one place of the multiplier first, and then with the tens place of the multiplier.

As per the data given in the question,

As Shanth drinks 1/2 * 6 ounces = 3 ounces of water in 2/3 hour.

To find the average amount of water she drinks in an hour, we need to find the equivalent amount of water in an hour.

So, the equivalent amount of water in an hour will be

Unit vectors for equilateral triangle sides: pq is 〈1,0〉, qp is 〈-0.5,√3/2〉, rq is 〈-0.5,-√3/2〉. Sum is zero vector.

a) The equilateral triangle has rotational symmetry of 120 degrees, so the unit vectors in the direction of each of the sides can be obtained by rotating the unit vector in the direction of pq by 120 degrees in the counter-clockwise direction.

Using 2D rotation matrix, the unit vector in the direction of qp can be obtained as 〈cos(120), sin(120)〉 = 〈-0.5, √3/2〉.

Similarly, the unit vector in the direction of rq can be obtained as 〈cos(240), sin(240)〉 = 〈-0.5, -√3/2〉.

b) To verify that the three unit vectors sum to the zero vector, we add up the vectors:

〈1,0〉 + 〈-0.5, √3/2〉 + 〈-0.5, -√3/2〉 = 〈0,0〉.

Thus, the three unit vectors sum to the zero vector as required.

The volume of the resulting solid as  V = 2π(0)(in e)e = 2πe^2in. can be found by using the method of cylindrical shells.

This method involves calculating the volume of a series of infinitesimally thin cylindrical shells that, when added together, form the solid of interest. The formula for the volume of a single cylindrical shell is V = 2πrhΔx, where r is the radius, h is the height, and Δx is the change in x.

To find the volume of the solid, we must first find the integral of the area of the region bounded by the graphs of y = in x, y = 0, and x = e. This integral can be found by integrating the equation y = in x from 0 to e, which gives us the area of the region. Then, we can use the formula V = 2πrhΔx to find the volume of the solid by substituting the radius of the shell (the radius of the y-axis) for r, the area of the region for h, and the change in x (e - 0) for Δx. This gives us the final volume of the solid as V = 2π(0)(in e)e = 2πe^2in.

The number of possible sequences of passes is 252.

When Alonzo has the ball for the first time, he has 4 people to pass it to. Then, for the next seven passes, each person has 3 people to pass it to. So, the number of sequences can be calculated as 4 x 3^7 = 252. This calculation is based on the principle of counting the number of combinations, where each person has a fixed number of options for passing the ball and the options change as the passes go on.

In this case, with 5 people, the total number of possible sequences of passes will be a function of the number of options available for each pass.

Answer:

After 17,190 years, the amount of carbon-14 left would be approximately 5 mg.

The half-life of carbon-14 is 5,730 years, which means that every 5,730 years, half of the remaining carbon-14 decays. To calculate the amount of carbon-14 remaining after 17,190 years, we can use the formula:

A = A0 * (1/2)^(t/T)

where:

A0 is the initial amount (80 mg)

t is the time elapsed (17,190 years)

T is the half-life (5,730 years)

A = 80 * (1/2)^(17,190/5,730)

A = 80 * (1/2)^3

A = 80 * (1/8)

A = 10 mg * 1/2

A = 5 mg

The following entropies are evaluated as H(X, Y ) = ∑p(x, y) log p(x, y), H(X|Y ) = ∑p(x, y) log p(x|y) = −E[ log(p(x|y)) .

We have the following joint probability distribution:

X/Y  0   1

0    1/3   1/3

1      0    1/3

The entropy of X is given by

H(X) = −p log p − (1 − p) log(1 − p) = H(p)

The entropy does not depend on the values that the random variable takes (0 and 1 in this case), but only depends on the probability distribution p(x).

The joint entropy is given by

H(X, Y ) = ∑p(x, y) log p(x, y).

The joint entropy measures how much uncertainty there is in the two random variables X and Y

taken together.

The conditional entropy of X given Y is

H(X|Y ) = ∑p(x, y) log p(x|y) = −E[ log(p(x|y))

The conditional entropy is a measure of how much uncertainty remains about the random variable

X when we know the value of Y.

For two variables, the chain rule becomes:

H(X, Y ) = H(X|Y ) + H(Y ) = = H(Y |X) + H(X).

Thus, the following entropies are evaluated as H(X, Y ) = ∑p(x, y) log p(x, y), H(X|Y ) = ∑p(x, y) log p(x|y) = −E[ log(p(x|y)) .

An equation to represent A, the area in square feet, as a function of w, the width in feet is A = 120W -2W²

According to the question, the school uses 120 feet of fencing material to enclose three sides of the play area. This means there are 3 sides.

Substitute into the perimeter of the rectangle will give:

120 = L + 2W

Area = LW

We know that the area of a rectangle is l × w

When w =10, length = 120 - 20 = 100, area = 100 x 10 = 1000

When w = 20, length = 120 - 40 = 80,  area =  80 x 20  = 1600

When w = 40, length = 120 - 80 = 40.  area = 40 x 40 = 1600.

So, the completed table will be

Width            Length          Area

w                  120 - 2w        (120 - 2w) w

In order to maximize the area with the given fencing, from the equation written above, then w = 30 feet and l = 60

So you use 73.02 minutes of talk time each month.

Cell phone is a portable electronic device that allows you to make calls, send messages, and perform various tasks such as browsing the internet.

Let x be the number of minutes of talk time you use each month.

The cost for the talk time each month is 19.80 + 0.09(x - 500), and the cost for e-mail is 0.2 * 19.80 = 3.96.

So, the total cost each month is 19.80 + 0.09(x - 500) + 3.96 = 23.76 + 0.09x - 46.04.

The total cost for 7 months is 7 * (23.76 + 0.09x - 46.04) = 166.32 + 0.63x.

We want to find the value of x that makes the total cost equal to $212.31, so we write:

166.32 + 0.63x = 212.31

Solving for x, we have:
