Answer: 769.3ft³
Step-by-step explanation:
V =
r²h
V = (3.14)(7)²(5)
V = 769.3ft³
9514 1404 393
Answer:
{2.96, 12.66}
Step-by-step explanation:
A graph shows the rocket will be 600 feet up after 2.96 seconds, and again at 12.66 seconds.
__
You can solve the equation h = 600 to find the times.
-16t^2 +250t = 600
-16(t^2 -15.625t) = 600
-16(t^2 -15.625t +7.8125²) = 600 -16(7.8125²)
-16(t -7.8125)² = -376.5625
t -7.8125 = √(376.5625/16) ≈ ±4.8513
t = 7.8125 ± 4.8513 ≈ {2.9612, 12.6638}
The rocket will be 600 ft above the ground 2.96 and 12.66 seconds after launch.
Answer:
A=40
Step-by-step explanation:
If A=100 and we need 2/5 the scale then all we do is divide 100 by five and multiply it by two giving us 40
x = -6, 8
Find the values of x by factoring, getting
