First, you need to find the height, in which it says “a height that’s half the length of the longer base side. Can you guess what that is between 7 and 5? It is 7. And you would find half of that which is 3.5. Now you know the height is 3.5. The formula to find a rectangular pyramid's volume is lwh/3 which you would do 7 * 5 * 3.5, which is equal to 122.5, and then you would divide that by 3, which is 40.833 which would round to 40.8, so there is your answer.
It is 40.8 units^3

We need to find the rate of change for the interval 7,9  and 4,6

We know b= 9 and a = 7

f(9) -f(7)

------------

9-7

How can i simplify<br><img src="https://tex.z-dn.net/?f=25%20-%20%28%20%5Csqrt%7B16%7D%20%20-%201%29%20%5Ctimes%20%283%20-%209%2

We will use PEMDAS rule to simplify the given expression.

PEMDAS rule is given by:

P
-Parentheses first

E
-Exponents (ie Powers and Square Roots, etc.)

MD-Multiplication and Division (left-to-right)

AS
-Addition and Subtraction (left-to-right)
25-(\sqrt{16} -1) * (3-9) *2

Step 1: P-parenthesis first.

(3-9) is -6

√16 -1 = 4-1 =3

So new expression becomes : 25-3*(-6)*2

Step 2:

Multiplying (-3)*(-6)*2

We get +36

So new expression becomes : 25 +36

Step 3: Addition

Adding 25 and 36 we get 61

So final answer is 61 .
