On top of a hill, a rocket is launched from a distance 80 feet above a lake. The rocket will fall into the lake after its engine
lisov135 [29]
For this case we have the following equation:
 h = -16t2 + 64t + 80
 To find the maximum height, we derive the equation:
 h = -32t + 64
 We match zero:
 -32t + 64 = 0
 We clear t:
 t = 64/32
 t = 2
 We substitute the value of t in the given equation:
 h (2) = -16 * (2) ^ 2 + 64 * (2) + 80
 h (2) = 144
 Answer:
 
The maximum height is 144 feet and the time to reach this height is 2 seconds.

Is it more difficult to run up a ramp with a slope of 1/5 or a ramp with a slope of 5? Explain.
VARVARA [1.3K]
It would be more difficult to run up a slope of 5 because it would be steeper. with a 1/5 slope you would have a rise over run but with a slope of 5 it would just be all rise

Question 5<br> Find the sum of the following geometric series.<br> 8+1.6+0.32+0.064 + ...
boyakko [2]

good morning,

Answer:

10×(1-0.2ⁿ)

Step-by-step explanation:

1.6/8=0.2

0.32/1.6=0.2

0.064/0.32=0.2

let S represent the sum of n term then S=8×[(1-0.2ⁿ)/(1-0.2)] = 10×(1-0.2ⁿ).
