Answer:
c. 6.5 seconds.
Step-by-step explanation:
We have been given that a a paper plane is thrown from the top of a 147-foot cliff into the water below, the height of the plane at any given time can be determined by the formula 
, where h is the height of the plane at t seconds.
To find the time, when plane will be at a height of exactly 20.25 feet, we will substitute 
in our given formula and solve for t as:
Take square root of both sides:
Since time cannot be negative, therefore, the plane will be at a height of exactly 20.25 feet after 6.5 seconds and option 'c' is the correct choice.
Answer:
the same as the original equation
Step-by-step explanation:
Since they don't intersect the slope is the same

Answer:
174.7
Step-by-step explanation:
Let's find the area of the two triangles
(2)(1/2)(11*7.7) = 84.7
Back rectangle
3 x 11 = 33
Front facing rectangle
3 x 9 = 27
Bottom rectangle
3 x 10 = 30
Total = 84.7 + 33 + 27 + 30 = 330 + 60 + 30 = 420
