Pls I really need help 40 points I’ve been stuck on this over an hour. Is my change in area and dimensions correct?
Answer:
you are correct.
if you multiply the base and height with 3
height: 3 * 4 = 12
base: 3 * 8 = 24
area = 1/2 * base * height = 1/2 * 24 * 12 = 144
change in dimensions: 3 * 1 = * 3
change in area is (144/16) = 9

A car requires 9 liters of gasoline to cover a distance of 108 km. If the car
spent 12.5 liters of gasoline, how far did the car travel?
Answer: 150km
Step-by-step explanation:
The question says that the car required 9 litres of gasoline to cover 108km which means we and then derive that:
9L = 108km
And we are trying to find out how much distance can cover:
12.5L =?
Therefore, in order to find out the distance, we need to figure out how much distance can 1L take the car
therefore:
1L = [tex]\frac{108km}{9L}[/tex] = 12km
So if we know how far 1L can take us, we can just multiply 12.5 litres by the 12km to find out the distance:
12.5L × 12km = 150km
So, therefore, 12.5 litres can cover 150km.

Write an exponential model given the two points (10,130) and (11,240).
Answer:
y = 130(24/13)^(x -10)
Step-by-step explanation:
The y-value changes by a factor of 240/130 = 24/13 for a unit change in the x-value. This means we can write the function as though it had an initial value of 130 and a growth factor of 24/13, translated 10 units to the right.
y = 130(24/13)^(x -10)
_____
Additional comment
This can also be written in the form ...
y = a·e^(kx)

Marco puts his coins into stacks. Each stack has 10 coins.
He makes 17 stacks of quarters.
He makes 11 stacks of dimes.
He makes 8 stacks of nickels.
How much money does Marco have in his stacks of coins?
Answer:
Marco has $57.50 in total.

The initial height is the y-intercept of the graph
slope of the graph = -2
Jordon interprets the only the slope correctly.
Aral interprets the only the initial height correctly.
Step-by-step explanation:
Slope = change in y ÷ change in x = (0 - 12) ÷ (6 - 0) = -12 ÷ 6 = -2
So the slope of the graph = -2
by inspection, the y-intercept = 12
Therefore, the equation for the line is y = -2x + 12

∠ and ∠ are complementary angles. If ∠ = (12x - 3)° and ∠ = (7x - 2)°, find the
∠.
Answer:
57 °
Step-by-step explanation:
Complementary angles = 90 °
Since, Your angle don't have ∠ [ ] Then Let let "C" and "y"
Thurs, C = 12x- 3 and y = 7x - 2
It is given that angles r and s are complementary angles. Two angles are complementary if they add up to 90 degrees. This means the sum of measures of angle r and angle s must be 90 degrees. So,
c + y = 90
12x - 3 + 7x - 2 = 90
19x - 5 = 90
19x = 95
x = 95/19
x = 5
Using the value of x in expression or r, we get:
c = 12x - 3 = 12(5) - 3 = 60 -3 = 57 degrees.
So measure of angle c is 57 degrees.
Hence, the ∠ is 57 °

Based on the graph given for f (x) construct the graph of f¹ (x). for f (x) find E, F and the formula of f (x) when it is known that it is a linear function.
Answer:
To find an inverse function, reflect a graph of a function across the line y=x (and find the resulting equation)
To reflect a linear function in the line y=x, find points on f(x) and then swap their x and y coordinates.
Points on f(x): (0, -4) (2, 0) (5, 6)
Points reflected in line y=x: (-4, 0) (0, 2) (6, 5)
Plot points (-4, 0) (0, 2) (6, 5) and connect to form a straight line - this is the inverse of the function: [tex]f^{-1}(x)[/tex]
To determine the equation of f(x):
Choose 2 points on f(x): (5, 6) and (0, -4)
Calculate the slope (gradient) by using:
[tex]m=\dfrac{\triangle y}{\triangle x}=\dfrac{y_2-y_1}{x_2-x_1}=\frac{6--4}{5-0}=2[/tex]
Using the slope-intercept form: y = mx + b
(where m is the slope and b is in the y-intercept)
From inspection of the graph, we can see the line crosses the y-axis at -4,
⇒ f(x) = 2x - 4
As the line is actually a line segment (with endpoints (0, -4) and (5, 6), then
f(x) = 2x - 4, 0 ≤ x ≤ 5
To determine the equation of [tex]f^{-1}(x)[/tex]:
Rewrite f(x) as [tex]y = 2x - 4[/tex]
Swap the x and y: [tex]x = 2y - 4[/tex]
Rearrange to make y the subject: [tex]y= \dfrac{1}{2}(x + 4)[/tex]
Replace y with [tex]f^{-1}(x)[/tex]
So the equation of the inverse is: [tex]f^{-1}(x)= \dfrac{1}{2}(x + 4)[/tex]
As the original function is a segment, then
[tex]f^{-1}(x)= \dfrac{1}{2}(x + 4), \ \ \ -4\leq x\leq 6[/tex]
(shown in blue on the attached diagram)
** I can't see any points labelled E and F on the original function. If they are the endpoints of the line segment of f(x), then they are (0, -4) and (5, 6) **
