The time of takeoff of this hovercraft would be 0 seconds, as if you were starting a timer. So, if you plug in 0 for x (unit for seconds) in your equation, it will look like this:
h(0) = -3(0 - 3)² + 108
Parenthesis first
h(0) = -3(-3)² + 108
Exponents next
h(0) = -3(9) + 108
Multiplication
h(0) = -27 + 108
Combine like terms
h(0) = 81: The height of the hovercraft at the time of takeoff is 81 meters!
Hope this helps :)

Answer:
The area of the black portion = 219.752280681013 cm²
Step-by-step explanation:
<u><em>the canvas has the shape of a square </em></u>
<u><em>with sides of length 8×4 = 32 cm</em></u>
Then
<u>• The area of the canvas</u>
= 32²
= 1024 cm²
<u>•• The area of the four circles</u>
= 4×(π×8^2)
= 804.247719318987 cm²
<u>••• The area of the black portion</u>
= 1 024 - 804.247719318987
= 219.752280681013 cm²
Answer:
Step-by-step explanation:
First lets fill in the variables
Now solve
3 - 9 = -6
2 - -1 = 3
-6/3 = -2
