Someone please help me graph! And I can someone please give me the 5 short answers at the bottom ?

Answers

Answer 1

Answer: y = (2/3)x - 1/3
y + 1/3 = (2/3)x
(3/2)*(y+1/3) = x
(3/2)y + 1/2 = x

f^-1(x) = (3/2)x + 1/2
This is the inverse you need to graph. You can plot this yourself, or use a graphing calculator.

The domain of f^-1(x) is all real numbers
The range of f^-1(x) is all real numbers

For the next 2, just plug in the values and solve:

f(2) = 1
f^-1(-19) = -28

Alexia made a down payment of $1825 on a car, and then paid 36 monthly payments of $415. If the loan had 0% interest, how much did Alexia pay for the car?

Answers

General Idea:

Amount of money paid for a loan with 0% interest can be given by the below formula:

Total amount = Down payment + Number of months* Monthly Payment

Applying the concept:

Substituting $1825 for down payment, 36 for number of months and $415 for monthly payment in the formula given above, we get...

Total amount $= 1825+36* 415=1825+14940=16,765$

Conclusion:

Alexia paid an amount of $16,765 for the car.

The regular octagon has a perimeter of 122.4 cm. Which statements about the octagon are true? Check all that apply.

Answers

Answer:

The length of segment XY can be found by solving for a in

$20^2-7.65^2=a^2$

The measure of the central angle $\angle ZXW$ is $45\degree$ .

Step-by-step explanation:

If the regular octagon has a perimeter of 122.4cm, then each side is $(122.4)/(8)=15.3cm$

The measure of each central angle is $(360\degree)/(8)=45\degree$

The angle between the apothem and the radius is $(45)/(2)=22.5\degree$

The segment XY=a is the height of the right isosceles triangle.

We can use the Pythagoras Theorem with right triangle XYZ to get:

$a^2+7.65^2=20^2$

$a^2=20^2-7.65^2$

Therefore, the correct options are:

The length of segment XY can be found by solving for a in

$20^2-7.65^2=a^2$

The measure of the central angle $\angle ZXW$ is $45\degree$ .

h(x)= 3^x

a) Solve the equation h^-1(x)= 2

Answers

Because the inverse of function h(x) = 3^x is h^-1 ( x ) = log 3 ( x ) , we solve the equation log 3 ( x ) = 2 ;
3^2 = x;
x = 9 ;

Use the property of inverse functions:
$h(h^(-1)(x))=x \n \n\hbox{if} \n h^(-1)(x)=2 \n \hbox{then} \nh(2)=x \n\Downarrow \nh(x)=3^x \nh(2)=3^2 \nh(2)=9 \n \n\boxed{x=9}$

What is the result of dividing 48a3 + 32a2 + 16a by 4a?

A. 12a2 + 8a + 4

B. 12a2 + 4a + 8

C. 12a + 8

D. 12a2 + 4a + 4

Answers

The required quotient is 12a2 + 8a + 4. Option A is correct.

Quotient to be determined when dividing 48a3 + 32a2 + 16a by 4a.

What is the quotient?

The quotient is that value when quantity is divided by some value.

Here,
= (48a3 + 32a2 + 16a)/4a.
= 48a3/4a + 32a2/ 4a + 16a/4a)
= 12a2 + 8a + 16

Thus, the required quotient is 12a2 + 8a + 4. When dividing 48a3 + 32a2 + 16a by 4a.
