If f(x)=2^x-1 and g(x)= x^2-1, determine the value of (f o g)(3)
zimovet [89]

Answer: 4

Step-by-step explanation:

( f o g ) (3) means f(g(3)) so...

First: plug 3 into g(x) = x^ (2-1)

3^ (2-1) is 3^1 = 3

Next: plug 3 into f(x)= 2^(x-1)

2^(3-1) is 2^(2) > 2×2 = 4

Answer:

C. y = 4x, table B, graph A

Step-by-step explanation:

Charges = $4 per hour (this is the slope, m,)

m = 4

The equation can be represented in the form of y = mx

Where,

m = slope = 4

Substitute m = 4 into y = mx

Thus:

y = 4x

✔️The table that represents the equation y = 4x showing that for 1 hour, the charges is $4 is table B (x = 1, y = 4).

Table B represents the parking cost.

✔️The equation with a slope of 4 is the equation that represents the parking cost. Thus, in graph A, when x = 1 (hour), y = 4 (cost).

Therefore, graph A is the answer.

1. A cylinder with a height of 5 in and a radius of 2 in is shown.
dexar [7]

Answer:

62.8 cubic inch

Step-by-step explanation:

For Cylinder

height (h) = 5 in

radius (r) = 2 in

Volume of Cylinder

= <em>π r² h</em>

= 22/7 * 2 * 2 * 5

= 22* 20/7

= 440/7

= 62.8 cubic inch

Thus, the volume of the cylinder is <em><u>62.8 cubic inch</u></em>
