If you borrow $900 for 6 years at
an annual interest rate of 7%, how
much will you pay altogether?
If you borrow $900 for 6 years at an annual interest rate of 7%. You will pay $1350.65
What is an annual interest rate?"An annual interest rate is expressed as an interest rate. It calculates what percentage of the principal you'll pay each year by taking things such as monthly payments into account."
According to the problem
If you borrow $900 for 6 years at an annual interest rate of 7%
You will pay = [tex]90(1+\frac{r}{100} )^{t}[/tex]
= [tex]900(1+\frac{7}{100} )^{6}[/tex]
= [tex]900(1.07)^{6}[/tex]
= $1350.65
Hence, you will pay $1350.65

What is the corresponding angle or side?
Answer:
Number 1 would be FK
Number 2 would be SQR
Answer:
1) FK
2) SQR
Step-by-step explanation:
In congruence statements such as these, each letter's position corresponds to the letter in the same position on the other side.
For example, in 1, MK corresponds to FK because M and F are in the same position and K is in the same position as itself (reflexive property).
In 2, FHG corresponds to SQR because each letter is in the same position in the given congruence statement.

Questions:
1.Which expression is a factor of n^2+3n-54?
2. The trinomial x^2-14x+49 can be expressed as?
1. (n+9) • (n-6) is the answer
The required, 1. factor of the expression n²+ 3n - 54 = (n + 6)(n - 9), 2. x² - 14x + 49 can be expressed as (x - 7)².
What are the factors?A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor.
3.
To factor the quadratic expression n² + 3n - 54, we need to find two numbers whose product is -54 and whose sum is 3. These numbers are 6 and -9.
Therefore, we can write:
n²+ 3n - 54 = (n + 6)(n - 9)
So the expression (n + 6)(n - 9) is a factor of n² + 3n - 54.
2.
The trinomial x² - 14x + 49 can be expressed as the square of a binomial. Specifically, it is the square of (x - 7):
(x - 7)² = (x - 7)(x - 7) = x² - 14x + 49
Therefore, x² - 14x + 49 can be expressed as (x - 7)².

Alejandro said that the slope of the line in the Example is because for points
2
(2, 140) and (0,0), the rise is 140 and the run is 2. Is Alejandro correct? Explain.
Answer:
Step-by-step explanation:
slope = M = rise/ run
P1=(2,140)
P2=(0,0)
M= (Y2-Y1) / ( X2-X1)
M = 0-140 /0-2
M = -140 / -2
M = 140 / 2
Yes, Alejandro is right
The slope of the line is the ratio of rise to the run. Therefore the line with points (2,140) and (0,0) has rice 140 and run 2. Hence the statement given by the Alejandro is correct.
Given information-Points of the line are (2,140) and (0,0).
The rise of the line is 140.
The run of the line is 2.
Slope of the line-
Slope of a line describes the steepness and the direction of the line. The slope of of line passing through the point [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] can be given as,
[tex]m=\dfrac{(y_2-y_1)}{(x_2-x_1)} [/tex]
Thus the slope of the line with points (2,140) and (0,0) is,
[tex]m=\dfrac{(0-140)}{(0-2)} \\ m=\dfrac{140}{2} \\ [/tex]
As the slope of the line is the ratio of rise to the run. Therefore the line with points (2,140) and (0,0) has rice 140 and run 2. Hence the statement given by the Alejandro is correct.

The height, h, in feet of a kicked soccer ball can be modeled by the function h(t) = -16t2 + 24t + 1, where t is in seconds. On its way down, the ball bounces off the crossbar of the goal, which is 8 feet above the ground. To the nearest tenth, when did the ball hit the cross bar?
Answer:
Step-by-step explanation:
let the height of a kicked soccer ball be expressed by the function:
h(t) = -16t^2 + 24t + 1 where t is in seconds
The ball hit the cross bar when the height is zero
The equation becomes
0 = -16t^2 + 24t + 1
16t^2 - 24t - 1= 0
t = 24±√24²-4(16)(-1)/2(16)
t = 24±√576+64/32
t = 24±√640/32
t = 24+25.298/32
t = 49.298/32
t = 1.54 secs
Hence the ball hit the cross bar at t = 1.6secs (to the nearest tenth)

D.
A′(-3, 3), B′(-1, 1), C′(-2, -3)
The missing figure is attached down
Answer:
The coordinates of the vertices of Δ A'B'C' are A' (-3, 3), B' (-1, 1), C' (-2, 3) ⇒ A
Step-by-step explanation:
If the point (x, y) reflected across the x-axis , then its image is (x, -y)
If the point (x, y) translated vertically up by k units then its image is (x, y + k)
Let us solve the question using the rules above
∵ The coordinates of Δ ABC are A (-3, 1), B (-1, 3), C = (-2, 1)
∵ Δ ABC reflected across the x-axis at first
→ By using the first rule above change the signs of y coordinates
∴ The image of A = (-3, -1)
∴ The image of B = (-1, -3)
∴ The image of C = (-2, -1)
∵ Then it translated 4 units up
→ Use the second rule above, where k = 4, add each y-coordinates by 4
∴ A' = (-3, -1 + 4)
∴ A' = (-3, 3)
∴ B' = (-1, -3 + 4)
∴ B' = (-1, 1)
∴ C' = (-2, -1 + 4)
∴ C' = (-2, 3)
The coordinates of the vertices of Δ A'B'C' are A' (-3, 3), B' (-1, 1), C' (-2, 3)

what is the slope of the graph of 2x - 5y =20
Answer:
2/5
Step-by-step explanation:
convert to slope-intercept form y=mx+b:
2x - 5y = 20
-5y = 20 -2x
y = -4 (-2/-5)x
y = 2/5x - 4
the slope of the graph represented by 2x - 5y = 20 is 2/5.
To find the slope of the graph represented by the equation 2x - 5y = 20, we need to rearrange the equation into slope-intercept form (y = mx + b), where m is the slope.
Let's start by isolating the term with y:
2x - 5y = 20
-5y = -2x + 20
Next, divide the entire equation by -5 to solve for y:
y = (2/5)x - 4
Comparing the equation with the slope-intercept form, we can determine that the slope (m) is 2/5. Therefore, the slope of the graph represented by 2x - 5y = 20 is 2/5.
