(a) Ann's monthly payment: $133.33
(b) Ann's total amount to repay the loan:$8000
(c) The total amount of interest Ann will pay:-$12000
What is amortized loan?
A loan that has planned, monthly payments that are applied to both the principle and interest accrued is known as an amortized loan.
To solve this problem, we need to use the following formula for an amortized loan:
[tex]Monthly\ payment = (Interest rate / 12) * Loan\ amount / (1 - (1 + (Interest \ rate / 12))^(-Term * 12))[/tex]
(a) Find Ann's monthly payment:
Substituting the given values into the formula, we get:
[tex]Monthly\ payment = (0.08 / 12) * 20000 / (1 - (1 + (0.08 / 12))^(-5 * 12))\\\\Monthly\ payment = 133.33[/tex]
Therefore, Ann's monthly payment is $133.33.
(b) Find Ann's total amount to repay the loan:
The total amount to repay the loan is equal to the sum of the monthly payments over the term of the loan. Since Ann's monthly payment is $133.33 and the term of the loan is 5 years, the total amount to repay the loan is equal to $133.33 * 5 * 12 = $8000.
(c) Find the total amount of interest Ann will pay:
The total amount of interest Ann will pay is equal to the total amount to repay the loan minus the loan amount. Since Ann's total amount to repay the loan is $8000 and the loan amount is $20000, the total amount of interest Ann will pay is equal to $8000 - $20000 = -$12000.
Note that the total amount of interest Ann will pay is a negative number because the loan amount is greater than the total amount to repay the loan. This means that Ann will end up paying less than the loan amount due to the amortization of the loan.

a meteorologist predicted that there would be 1.0 inches of rainfall from a storm instead there was 2.2 inches of rainfall
The percentage change of the rainfall the meteorologist predict is 55%
How to determine the percentage change of the rainfall the meteorologist predict?From the question, we have the following parameters that can be used in our computation:
Predicted amount of rainfall = 1.0 inches
Actual amount of rainfall = 2.2 inches
The percentage change of the rainfall the meteorologist predict is calculated as
Percentage change = (Actual amount of rainfall - Predicted amount of rainfall)/Actual amount of rainfall * 100%
Substitute the known values in the above equation, so, we have the following representation
Percentage change = (2.2 - 1.0)/2.2 * 100%
Evaluate the difference in the above equation, so, we have the following representation
Percentage change = 1.2/2.2 * 100%

In which direction does the parabola defined by the equation y = -x + 2 open?
Answer:
Downward
Step-by-step explanation:
A parabola is a curve that is shaped like a U. The direction in which a parabola opens depends on the sign of the coefficient of the x^2 term in the equation defining the parabola. If the coefficient is positive, the parabola opens upwards. If the coefficient is negative, the parabola opens downward.
In the equation y = -x + 2, the coefficient of the x^2 term is 0, so the direction of the parabola does not depend on it. However, the coefficient of the x term is -1, which is negative. This means that the parabola defined by this equation opens downward.

After solving the equation the complex number 19 + 19i.
What is polar form?
In mathematics, polar form is a way of representing a complex number in terms of its magnitude (the distance from the origin to the point on the complex plane) and its argument (the angle formed by the positive x-axis and the line connecting the origin to the point on the complex plane).
To plot the complex number 19 + 19i on the complex plane, you can represent it as a point with coordinates (19, 19). The complex plane is a two-dimensional coordinate system in which the x-axis represents the real part of a complex number and the y-axis represents the imaginary part.
The complex number 19 + 19i can also be written in polar form and in exponential form.
In polar form, a complex number is represented by its magnitude (the distance from the origin to the point on the complex plane) and its argument (the angle formed by the positive x-axis and the line connecting the origin to the point on the complex plane).
The magnitude of the complex number 19 + 19i is:
magnitude = √(19^2 + 19^2)
= √(361 + 361)
= √(722)
= 27
The argument of the complex number 19 + 19i is:
argument = atan2(19, 19)
= 45°
Therefore, the complex number 19 + 19i can be written in polar form as:
19 + 19i = 27 * cis(45°)
In exponential form, a complex number is represented as the product of its magnitude and the complex exponential cis(θ), where θ is the argument of the complex number.
Therefore, the complex number 19 + 19i
Polar form is usually written as:
r * cis(θ)
where r is the magnitude of the complex number and θ is the argument, expressed in radians.

During a fireworks display, a shell is shot into the air with a velocity of 58 m/s, its height in meters after t seconds is given by y=58t-20t^2
Find velocity when t=0.5
The velocity of a shell shot into the air with a velocity of 58 m/s, its height in meters after t seconds is given by y=58t - 20t² is 38 m / s.
What is velocity?When anything is moving, its velocity tells us how quickly that something's location is changing from a certain vantage point and as measured by a particular unit of time.
If a point moves along a path and covers a certain distance in a predetermined amount of time, its average speed over that period of time is equal to the distance covered divided by the travel time. A train traveling 100 kilometers in two hours, for instance, is doing it at an average speed of 50 km/h.
Given:
Height equation, y = 58t - 20t²,
The time, t = 0.5 seconds,
The initial velocity, u = 58 m/s,
Calculate the height at 0.5 sec,
y = 58 × 0.5 - 20 × 0.5²
y = 24 m
Calculate the acceleration at 0.5 sec by using the motion equation given below:
[tex]s = ut+1/2at^2[/tex]
24 = 58 × 0.5 + 1 / 2 × a × 0.5²
-5 = 0.125 × a
a = - 40 m / s²
Calculate the velocity by using the formula given below,

v = 58 + (-40) × 0.5
v = 38 m /s

yes; y=2 x
yes; y=5 x
yes; y=7 x
no; y does not vary directly with x.
The ratio y/x is not constant (k) for all the data points, then y does not vary directly with x.
What is the constant of variation?
The constant of variation is the number that relates two variables that are directly proportional or inversely proportional to one another.
We have,
x y
2 10

6 36
To determine whether y varies directly with x, you need to see if the ratio of y to x is constant for all the data points.
If y varies directly with x, then the ratio y/x will be constant for all the data points. In this case, you can write an equation for the direct variation in the form y = kx, where k is the constant of variation, which is equal to the ratio y/x.
If the ratio y/x is not constant for all the data points, then y does not vary directly with x.
so, let's see the k constant of variation,
k = y/x
k = 2/10 =1/5
k = 4/24 = 1/6
k = 6/36 = 1/6
so, k = 1/5, k=1/6, k=1/6.
Hence, the ratio y/x is not constant (k) for all the data points, then y does not vary directly with x.

y=5/4x+1
Step-by-step explanation:
slope intercept form is y=mx+b
M- slope
B- y intercept
We already know slope
y=5/4x+b
To find b we fill in the coordinates we know (-8,-9)
-9=5/4(-8)+b
-9=-40/4+b
-9=-10+b
+10 +10
1=b
Now. We fill it in
y=5/4x+1

a line's slope is 0, and it's y intercept is -7. what is its equation in slope intercept form?
Find the distance between the points (6.6, 7.9) and (6.6, 4.7).
Answer:
3.2
Step-by-step explanation:
Compute the Euclidean distance between the following points:
p_1 = (6.6, 7.9) and p_2 = (6.6, 4.7)
The Euclidean distance between points (x_1, y_1) and (x_2, y_2) is:
sqrt((x_1 - x_2)^2 + (y_1 - y_2)^2)
Substitute (x_1, y_1) = (6.6, 7.9) and (x_2, y_2) = (6.6, 4.7):
= sqrt((6.6 - 6.6)^2 + (7.9 - 4.7)^2)
6.6 - 6.6 = 0:
= sqrt(0^2 + (7.9 - 4.7)^2)
0^2 = 0:
= sqrt(0 + (7.9 - 4.7)^2)
| 7. | 9
- | 4. | 7
| 3. | 2:
= sqrt(3.2^2)
Cancel exponents. sqrt(3.2^2) = 3.2:
Answer: = 3.2
