Answer:
you have to add
Step-by-step explanation:
Answer:
(1) 7 ÷ 7^3 x 7 = <u>1/7</u>
(2) 8^2 ÷ (8 - 4)^2 = <u>4</u>
<u></u>
(3) -4 + 3^3 ÷ 5 = <u>1.4</u>

The side length of the square base is 18 inches and the height of the pyramid is 9 inches.
Step-by-step explanation:
Step 1:
The volume of a square pyramid is calculated by multiplying the square of the base edge with the height of the pyramid and
.
The volume of a square pyramid, 
Step 2:
From the given diagram, the base edge is the length of the four base edges which is x inches in this pyramid. a = x inches.
The height of the pyramid is from the base to the top, h =
inches .
The volume of a square pyramid, 
Substituting the known values, we get

![x^{3} = 6(972) = 5,832. x = \sqrt[3]{5,832} = 18.](https://tex.z-dn.net/?f=x%5E%7B3%7D%20%3D%206%28972%29%20%3D%205%2C832.%20x%20%3D%20%5Csqrt%5B3%5D%7B5%2C832%7D%20%3D%2018.)
So x is 18 inches long.
The side length
inches.
The height of the pyramid
inches.
Answer:
12+3x=27
Step-by-step explanation:
Follow the words and write it as you read it, if it's (times) you multiply and if it's (larger), it's addition.
Let y = 12 e^2x
e^2x = y/12
Taking
[email protected]ln e^2x = ln (y/12)
2x = ln (y/12)
x = (1/2) ln (y / 12)
so the inverse h-1(x) = (1/2) ln ( x / 12)
