Question

H(15)=-16.1(15)^2+150

Answer 1

Let’s remember orders of operation while we’re solving this problem.
-16.1 • 15^2 + 150
Let’s solve the exponents.
-16.1 • 225 +150
Now multiplication.
-3,622.5 + 150
Now adding.
-3,472.5
The answer to the equation is -3,472.5.
Now, let's divide -3,472.5 by 15 to find H.
-3,472.5÷15= -231.5
H= -231.5

Answer 2

I'm assuming you're trying to find H so this is how you start:

first solve what [-16.1(15)^2+150] is

-16.1 (15)^2 + 150
-16.1 x 225 + 150 =
-3622.5 + 150 =
-3472.5 = H(15)

now you divide -3472.5 by 15 to get H

-3472.5 / 15 =
-231.5 = H
