Answer:

(a) Their rates of change differ by 2

Step-by-step explanation:

Given

See attachment for functions M and P

Required

Determine what is true about the rates of M and P

First, we calculate the slope (i.e. rate) of both functions.

Slope is calculated as:

m = \frac{y_2 -y_1}{x_2 - x_1}

From the table of M, we have:

(x_1,y_1) = (-2,-9)

(x_2,y_2) = (2,11)

So, the slope is:

m_M = \frac{11 --9}{2--2}

m_M = \frac{20}{4}

m_M = 5

For function P, we have:

y = 7x + 9

A function is represented as:

y = mx + b

Where:

m = slope

So, by comparison:

m_P = 7

At this point, we have:

m_M = 5 --- Slope of M

m_P = 7 --- Slope of P

<em>Only option (a) is true because both slopes differ by 2. i.e. 7 - 5 = 2</em>

<em>Other options are not true</em>

The volume of the prism shown is 72. in3
Vesna [10]

Answer:

  24 in³

Step-by-step explanation:

The volume of a prism is given by the formula ...

  V = Bh

where B is the area of the base, and h is the height.

The volume of a pyramid is given by the formula ...

  V = (1/3)Bh

where B and h have the same definitions.

For a pyramid with the same B and h as a prism, the volume is 1/3 that of the prism:

  (1/3) × (72 in³) = 24 in³ . . . . volume of the pyramid
