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 Answer is B.
Step-by-step explanation:
I took the quiz on Edge.
Answer:
y = 8x+7
Step-by-step explanation:
firstly reduce the equation to an arithmetic series starting from the 0th term so:
7, 15, 23, 31, 39....
Secondly, identify the common difference: 8
we now know that the answer must contain 8x
Thirdly, form the equation 8x + c = y where y is a constant. Afterwards insert the values of any given x and y so:
8*0 + c = 7
c = 7
Thusly we now know that the series and thus equation is 8x+7 = y

Answer:
5.61; 8.5 %
Step-by-step explanation:
Tax = $1.87 per $22 meal
For a $66 meal,
Tax = 66 × 1.87/22
Tax = 3 × 1.87
Tax = $5.61
=====
Tax rate = 1.87/22 × 100
Tax rate = 0.085 × 100
Tax rate = 8.5 %
