s(t) = 5t⁴ - 4. Find t when a = 0. A) 60 B) -60 C) 5 D) -5 E) 0

Quizplus · Accepted Answer

When a = 0, we need to find the value of t, such that s(t) = 0. From the given function s(t), we observe that there are two instances where s(t) can be equal to 0 - at t = 0 and at t = 5. At t = 0, we have s(t) = 5(0)⁴ F1F1F1S1F1F1F10 = 0. At t = 5, we have s(t) = 5(5)⁴ F1F1F1S1F1F1F10 = 5⁴ F1F1F1S1F1F1F1. Since we are only interested in the value of t when a=0, the correct answer is t=0, which corresponds to the answer choice E.

S(t) = 5t4 - 4

S(t) = 5t⁴ - 4
