Answer:
514.5552
Step-by-step explanation:
:)
The slope is greater in the first graph
For this case we must add the given series. We expanded the series for each of the values of i, that is, from 1 to 5:
We add the terms:

Finally, the value of the given series is 45.
Answer:
45
Answer about 1.77 seconds.
f(t) = -16 t^2 + 25t + 6
f(t) = height.
hieght = 0 = -16t^2 + 25t + 6
Find t using the quadratic formula,
t = ( - 25 +/- √[25^2 - 4 (-16)(6)] ) / [2*(-16)]
t = [-25 +/- √ (625 + 384) ] / -32
t = [-25 +/- 31.76] / -32.
You will obtain two results one positive and one negative. Take the positive only as the other one has no physical meaning. t = 1.77 s.
