What is sue’s monthly payment be?
Plz guys help me pass math
Plz answer this last question on my test
Plz show all the working
God bless you brother or sister
Answer ASAP
Answer:
Monthly payment is $247.53
Step-by-step explanation:
Firstly, we need to calculate the total amount to be paid back
we have this by calculating using the compound interest formula;
That will be;
A = P( 1 + r/n)^nt
where A is the amount to be paid back
P is the amount borrowed = $8,000
r is the interest rate = 3.6% = 3.6/100 = 0.036
n is the number of times we are compounding per year; since it is monthly, this is 12
t is the number of months which is 3
Substituting these values, we have
A = 8000( 1 + 0.036/12)^(12 * 3)
A = 8000(1 + 0.003)^36
A = 8000( 1.003)^36
A = $8,910.94
To know the monthly payment, we divide this by the number of months
That will be;
$8,910.94/36
= $247.53

The height, h, of an object that is thrown upwards into the air can be represented as h = 0.5at2 + v0t + h0, where a represents the acceleration due to gravity (– 32 ft/s)
2), v0 represents the initial velocity, in feet per second, h0 represents the initial height of the object, in feet, and t represents time, in seconds.
Part A:
A ball thrown upwards from the top of a 64–ft high building with an initial velocity of 48
ft/s.Write an equation that could be used to determine the time, t, in seconds, for the ball to reach the ground. Assume ground level is at a height of 0 ft.
Part B:
Determine the time, t, in seconds, that takes the ball to reach the ground and explain how you determined your answer.

Step-by-step explanation:
The linear equation is y=mx+b
A= y= -2x+7.
-2 represents he slope and 7 represents the y intercept.
B= y= -[tex]\frac{3}{2}[/tex]x+ 6
-[tex]\frac{3}{2}[/tex] is the slop and 6 is the y intercept.

Which algebraic representation matches the reflection above?
O A. (x, y) = (x,y)
B. (x, y) -(-x, y)
OC. (x,y) (x,-))
OD. (x, y) (-X, -y)
The algebraic representation which matches the above reflection is D. (x, y) → (-x, -y).
What is Reflection?Reflection is a type of geometric transformation where the figure is flipped. In other words, a figure when undergoes reflection becomes it's mirror image.
From the graph, it is seen that a quadrilateral is reflected across the Y axis.
Find the corresponding coordinate points of the quadrilateral in order to find the algebraic representation.
From the first figure, consider the vertex point (1, 1).
The corresponding point on the second figure is (-1, -1).
That is, the point (x, y) is changed to (-x, -y).
So the representation is (x, y) → (-x, -y).
Hence the correct algebraic representation is (x, y) → (-x, -y).

The polar exhibit at the zoo has only penguins and seals. There are 14 penguins for every 6 seals. What percent of the exhibit is seals?
Answer:
42.85%
Step-by-step explanation:
Given that,
The polar exhibit at the zoo has only penguins and seals. There are 14 penguins for every 6 seals.
The percentage is given by :
[tex]\%=\dfrac{6}{14}\times 100\\\\=42.85\%[/tex]
So, 42.85 % of exhibit are seals.
A fruiterer has some apples and pears in the ratio of 2:5. He sold 261 pears and bought 261 more apples. After that, he had as many apples and pears. How many apples did he have at first.
Answer:
The number of apples the fruitier have at first is 348 apples
Step-by-step explanation:
The given parameters are;
The ration of the apples to pears the fruitier has = 2:5
The number of pears he sold = 261 pears
The number of apples he bought = 261 apples
The new ratio of apples to pears the fruitier then has = 1:1
Let 'x', represent the initial number of apples the fruitier has at first, and let 'y', represent the initial number of pears the fruitier has at first
Therefore, we have; x:y = 2:5
x/y = 2/5
∴ 5·x = 2·y
x = 2·y/5...(1)
(x + 261):(y - 261) = 1:1
∴ (x + 261)/(y - 261) = 1
x + 261 = y - 261...(2)
Substituting the value of 'x' from equation (1) in equation (2), gives;
2·y/5 + 261 = y - 261
261 + 261 = y - 2·y/5 = 3·y/5
522 = 3·y/5
∴ y = 5 × 522/3 = 870
The number of pears the fruitier have at first, y = 870 pears
x = 2·y/5 = 2 × 870/5 = 348
The number of apples the fruitier have at first, x = 348 apples.
A plane flying due west at 120 m/sec is blown due south at 54 m/sec. by a strong wind. Find the plane’s resultant velocity and direction angle as a degree.
velocity = ___ m/sec (round answer to nearest whole number)
Direction angle = ____ ° (round answer to nearest whole number)
Answer:
1) Velocity = 132 m/sec
2) Direction angle = 24° South of West
Step-by-step explanation:
1) The speed with which the plane is flying, [tex]v_{plane}[/tex] = 120 m/sec
The direction in which the plane is flying = Due West
The speed of the blowing strong wind, [tex]v_{wind}[/tex] = 54 m/s
The direction of the strong wind = Due South
The vector form of the given velocities are;
[tex]v_{plane}[/tex] = -120·i
[tex]v_{wind}[/tex] = 54·j
The resultant velocity in vector format, [tex]\underset{\textbf{v}}{\rightarrow}[/tex] is given as follows;
[tex]\underset{\textbf{v}}{\rightarrow}[/tex] = -120·i + 54·j
Therefore, the magnitude of the resultant velocity, [tex]\left |\underset{v}{\rightarrow} \right |[/tex], is given as follows;
[tex]\left |\underset{v}{\rightarrow} \right |[/tex] = √((-120)² + (54)²) = 131.590273197
∴ The magnitude of the plane's resultant velocity, [tex]\left |\underset{v}{\rightarrow} \right |[/tex] ≈ 132 m/sec, when rounded to the nearest whole number
2) The direction angle of the plane's resultant velocity, θ, is given as follows;
[tex]\theta = arctan \left ( \dfrac{\left |v_{wind}\right |}{\left |v_{plane}\right |} \right)[/tex]
Therefore, by substituting the known values, we have;
[tex]\theta = arctan \left ( -\dfrac{54}{120} \right) = -24.227745317954169522385424019918 ^{\circ}[/tex]
∴ By rounding to the nearest whole number, the direction angle of the plane's resultant velocity = θ ≈ -24° = 204° which is 24° South of West.

Step-by-step explanation:
One of the roots of the equation 5x^2-36x+t=0 is five times as big as the other root. Find the value of t.
Answer:
t = 36
Step-by-step explanation:
If you divide the equation by 5, you have ...
x^2 -7.2x +t/5 = 0
The opposite of the sum of the roots is the coefficient of the linear term, so is 7.2. If the roots are "r" and "5r", then their sum is r+5r = 6r, so the value of r is.
7.2/6 = 1.2
The roots are 1.2 and 5·1.2 = 6.
The constant term t/5 is the product of the roots, so ...
t/5 = 1.2 · 6
t = 6·6 = 36 . . . . . multiply by 5
Line segment AB is 14 units long. If the line segment AB is reflected in the x-axis to form A'B', How many Units long will A'B' be?
As the line segment AB is reflected in the x-axis to form A'B', A'B' will be 14 unit long.
What is reflection?A reflection is referred to as a flip in geometry. A reflection is the shape's mirror image. A line, called the line of reflection, will allow an image to reflect through it.
Every point in a figure is said to reflect the other figure when they are all equally spaced apart from one another. The reflected picture should have the same size and shape as the original, but it faces the opposite way. Changes in position during contemplation may also result in translation.
Given length of the line segment AB is 14 unit.
Then, after reflection in the x-axis, line segment AB forms A'B'.
As the reflected picture should have the same size and shape as the original, length of the line segment A'B' will be 14 unit.

The slope of the line is 3/4. Find the rise if the run is 8.
Answer: Rise is 6
Step-by-step explanation:
3=rise and 4 is run so if run becomes 8 then rise is 6
Step-by-step explanation:
Slope is defined as rise over run.
[tex]m = \frac{y}{x}[/tex]
if the slope (m) is 3/4, and the rise (y) is 8, you might substitute those values into the equation and solve for x.
