To write a line that is perpendicular you have flip the slope and change the sign so it would be -1/2, then you carry on like normal. So the answer is:
y-6= -1/2(x-9)
Answer:
x²+8x+16
Step-by-step explanation:
f(x) = (x+4)²
= (x+4)(x+4)
= x² + 4x + 4x + 16
= x² + 8x + 16
Answer: f(g(x))=x and g(f(x)) = x
f⁻¹(x) = g(x) YES ARE INVERSES
f⁻¹(x) ≠ g(x) NOT INVERSES
<u>Step-by-step explanation:</u>
Inverse is when you swap the x's and y's and then solve for y.
If f⁻¹(x) = g(x), then they are inverses of each other.
Similarly, if g⁻¹(x) = f(x), they are inverses of each other.
<em>NOTE: You can also use composition to determine if they are inverses --> If (fog)(x) = x, then they are inverses of each other.</em>

The bottom is (25 x 20) = 500 of whatever those units are, squared. Each long side is (25 x the depth of the pool, which we don't know), and each end is (20 x depth).
