Answer:
Step-by-step explanation:
100 = -16t^2 + 92t
16t^2-92t + 100 = 0
4t^2 - 23t + 25 = 0
t = [23 ±√(23^2-4(4)(25))]/[2(8)] ≈ 1.5, 4.3
The rocket has altitude of 100 ft at 1.5 sec and 4.3 sec.
:::::
0 = 16t^2-92t = t(16t-92)
t = 0, 5.75
Rocket is in the air for 5.75 seconds
3/8 is your answer, it is .375
4/7 would be a lil over .50
2/3 would be .66*
3/5 would be .60

Answer:
The angle is 120 degrees.
Step-by-step explanation:
Supplementary angles add up to 180 degrees.
So if our angle is x it's supplement is 180 - x.
So we have the equation:
x = 2(180 - x)
x = 360 - 2x
3x = 360
x = 120 (answer).
