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 :)

Yuri [45]

Answer:


Step-by-step explanation:

This is what i get what i understand from your question .

Kurt earns $7 per hour for doing chores. his goal is to make at least $35 each week


So ,

$7 =per hr

X= unknown hrs

$35= goal


7 x =35


Divide both sides by 7 to get x alone representing hrs.


X= 35/7

X= 5


So 5 hrs per week to make 35 a week.


5×7=35

35=35
