Answer: $31,920.

Step-by-step explanation:

The banker's rule is a method used by lenders to determine the maximum amount of money that a borrower can afford to repay. According to this rule, the maximum amount of money that Lee can afford to borrow is determined by multiplying his annual income by a factor of 0.28.

Using this rule, the amount that Lee can afford to borrow can be calculated as:

Maximum affordable monthly payment = 0.28 x monthly income

Maximum affordable monthly payment = 0.28 x (24700/12)

Maximum affordable monthly payment = 0.28 x 2058.33

Maximum affordable monthly payment = 576.66

Therefore, Lee can afford to make monthly payments of up to $576.66. To calculate the total amount he can borrow, we need to determine the total cost of the loan, including principal and interest.

Assuming a 5-year loan with an interest rate of 4%, the total cost of the loan can be calculated using an online loan calculator or spreadsheet software.

Plugging in the numbers, the total amount that Lee can borrow is approximately $31,920.

It's important to note that this calculation is based on the banker's rule and assumes that Lee has no other debt obligations. Actual loan approval and loan amounts may vary depending on other factors such as credit score, debt-to-income ratio, and other lender-specific requirements.

The integer that represents the amount of time in seconds the ball takes to reach the end of the ramp is 9.

To find the amount of time in seconds it takes for the ball to reach the end of the ramp, we need to divide the total distance by the rate of descent.

The total distance the ball needs to travel is 18 feet, and it descends 2 feet each second.

Therefore, the time it takes for the ball to reach the end of the ramp can be calculated as follows:

time = distance / rate

time = 18 feet / 2 feet/second

time = 9 seconds

So, the integer is 9.

Since the gravitational force is directly proportional to the mass, we can see that Satellite D has the greatest mass and therefore the greatest gravitational force with Earth. Therefore, the correct option is D.

To determine which satellite has the greatest gravitational force with Earth, we need to use the formula for gravitational force, which is:

force = (G x m1 x m2) / r^2

where G is the gravitational constant, m1 and m2 are the masses of the two objects, and r is the distance between the centers of the objects.

Since the mass of Earth is much greater than any of the satellites, we can assume that the distance between Earth and each satellite is the same. Therefore, we can compare the gravitational force of each satellite with Earth by calculating:

force = (G x Earth's mass x satellite's mass) / distance^2

Using this formula and plugging in the given values, we get:

For Satellite A: force = (G x Earth's mass x 375 kg) / (320 km)^2

For Satellite B: force = (G x Earth's mass x 250 kg) / (320 km)^2

For Satellite C: force = (G x Earth's mass x 50 kg) / (320 km)^2

For Satellite D: force = (G x Earth's mass x 500 kg) / (320 km)^2

One way to predict occurrences of a disease for a future year based on previous years' data is to use exponential modeling.

Specifically, the formula for exponential growth or decay can be used to project the number of cases for a future time period based on the growth or decline rate observed in the past.

For example, let's say that we have data on the number of cases of a certain disease for the past 10 years. We can use this data to fit an exponential model that describes the growth or decline rate of the disease over time.

Once we have this model, we can use it to predict the number of cases for a future year. For instance, if the model predicts that the disease will grow at a rate of 5% per year, we can use this rate to estimate the number of cases for the next year by multiplying the current number of cases by 1.05. By doing this, we can forecast the occurrence of the disease for the next year based on the previous years' data.

Inverse operations are operations which undo the operation which is done to the equation.

(a) 1/2 x² - 4 = 0

Adding both sides by 4,

1/2 x² = 4

Multiplying both sides by 2,

x² = 8

Taking the square root on both sides,

x = ±√8 = ±2√2

(b) (x - 5)² = 18

Taking the square root on both sides,

x - 5 = ±√18

x - 5 = ±3√2

Adding 5 on both sides,

x = ±3√2 + 5

(c) 2x² + 7 = 71

Subtracting by 7 on both sides,

2x² = 64

Dividing by 2 on both sides,

x² = 32

Taking the square root on both sides,

x = ±4√2

(d) 5 (x + 2)² + 37 = 487

5 (x + 2)² = 450

Dividing by 5 on both sides,

(x + 2)² = 90

Taking the square root on both sides,

x + 2 = ±√90

Subtracting by 2 on both sides,

x = ±√90 - 2

(e) (x - 4)² /3 + 8 = 17

Subtracting by 8 on both sides,

(x - 4)² /3 = 9

Multiplying both sides by 3,

(x - 4)² = 27

Step-by-step explanation:

Given three systems of equations, you want to know the operations that transform one system to the next.

Equation B2 is unchanged from equation A2, eliminating choices B and C.

Equation B1 is not a simple multiple of equation A1, eliminating choice A.

Knowing the answer is choice D, we need to find the multiplier k of equation A2 that is being added to A1. We can find that using the x-coefficients:

  k(-3) +5 = -4

  -3k = -9 . . . . . subtract 5

  k = 3 . . . . . . . divide by -3

Then we have ...

  3 × [A2] + [A1] ⇒ [B1] . . . . . . . choice D

Using the same tactics as above, we see that [C1] is unchanged from [B1], eliminating choices A and D.

[C2] is not a simple multiple of [B2], eliminating choice B.

Using the y-coefficient to find k, we have ...

  k(1) +2 = 0

  k = -2 . . . . . . . . subtract 2

Then we have ...

  -2 × [B1] + [B2] ⇒ [C2] . . . . . . . . choice C

The graph of the function q(x) = -9/2x^2 is a downward-facing parabola with vertex at the origin (0, 0).

The graph of the quadratic function q(x) = -9/2x^2 is a downward facing parabola because the coefficient of x^2 is negative. The vertex of the parabola can be found by using the formula x = -b/2a, where a is the coefficient of x^2 and b is the coefficient of x. In this case, a = -9/2 and b = 0, so the vertex is at x = 0.

To find the y-coordinate of the vertex, we substitute x = 0 into the equation q(x) = -9/2x^2. This gives us q(0) = 0, so the vertex is at the point (0, 0).

Since the coefficient of x^2 is negative, the graph of the function opens downwards. The value of the function decreases as we move away from the vertex in either direction.

Therefore, the graph of the function q(x) = -9/2x^2 is a downward-facing parabola with vertex at the origin (0, 0).

A function can have zero to many parameters, and it can return only one (option c).

In mathematics, a function is a rule that maps each element from one set, called the domain, to a unique element in another set, called the range.

The number of parameters a function can take determines the number of arguments required to call the function.

For instance, a function f(x) takes one parameter, and it requires one argument to be called.

On the other hand, a function g(x,y,z) takes three parameters, and it requires three arguments to be called. However, a function h() takes no parameters and does not require any argument to be called.

Answer:

To find out how many giant parade balloons could be filled with 6.2 billion cubic feet of helium, we can divide the total volume of helium by the volume of one balloon:

Number of balloons = Total volume of helium / Volume of one balloon

First, we need to convert 6.2 billion cubic feet to cubic feet:

6.2 billion = 6,200,000,000

Now we can calculate the number of balloons:

Number of balloons = 6,200,000,000 / 700,000

Number of balloons = 8,857.14

So, approximately 8,857 giant parade balloons could be filled with 6.2 billion cubic feet of helium.

The expression (x^2 -3x+7) cannot be simplified further because there are no like terms to combine or any other operations to perform. It is already in its simplest form.

The expression (x^2 -3x+7) is a quadratic expression, meaning it has a degree of 2. It cannot be simplified further because there are no like terms to combine, which is the only operation that can be performed to simplify polynomials.

To understand this, let's look at the individual terms of the expression. The term x^2 is the highest degree term, which means it has the greatest power of x.

The term -3x is the linear term, which means it has a degree of 1. And the constant term is 7, which means it has a degree of 0.

Since the terms have different degrees and there are no like terms, there is no way to simplify the expression any further.
