Answer:
14.52 seconds.
Step-by-step explanation:
We have been given that the height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation
Because the area of a trapezoid is A= ((a+b)/2)h, where a is the length of the top, b is the length of the base, and h is the height, you plug that in to find your answer.
This trapezoid is sideways, but the top of it is 7m (which is a) and the base is 10 m (which is b), add a and b to get 17, A = ((17)/2)h
Now divide by 2 to get A = (8.5)h
Because the height is 9, A = (8.5)9 = 76.5
The area of the trapezoid alone is 76.5m
Answer:
If I'm thinking right then the answer should be 5% ?
There's 8 students total if I'm correct?
2 people got 15.
2 people got 16.
1 person got 17.
2+2+1=5
2 person got 14.
1 person got 12.
2+1=3 There's 8 students total. but the answer should be 5%.
Step-by-step explanation:
90 degree - 22 degree = 68 degree
use sin rule
sin90/x = sin68/56
x =60.4 degree
