F(x) = x² - 81
Finding f⁻¹(x) the inverse function
Let y = f(x) and solve for x.
y = x² - 81
y + 81 = x²
x² = y + 81
x = √(y + 81)
Recall f(x) = y, that means x = f⁻¹(y)
x = √(y + 81)
f⁻¹(y) = √(y + 81)
Therefore f⁻¹(x) = √(x + 81)
Answer:
The 25,000 adult American pine trees in the forest.
Step-by-step explanation:
Consider the provided information.
It is given that the forest contains 25,000 adult American pines. The study involves collecting heights from 250 randomly selected adult American pine trees and analyzing the results.
A population is the set of data which includes all of the elements. If one or more observations are drawn form the population then it called a sample.
Here the population is 25,000 adult American pines.
Thus, the required answer is: The 25,000 adult American pine trees in the forest.
Answer:
592
Step-by-step explanation:
A=2(wl+hl+hw)
A=2(8*10+12*10+12*8)=592
Photic zone: seaweeds and corals live here
aphotic zone: mid-ocean level where no light reaches
deep ocean floor: animals that glow are found here

Answer:
The value would be
Step-by-step explanation:
What is the value of x in: 4x+3y=12 and 2x-3y=-30 *
4x + 3y
The answer is x = 2 - 3y = 4
3y = 30
So 2x + 3y = 12 is
X = 3 - 3y/4
2x - 3y = 30
X = 15 + 3y/2
