Find the position and velocity of an object moving along a straight line with the given acceleration, initial velocity, and initial position. a(t) =cos(πt), v(0)=55, s(0)=77 the velocity is v(t)= (type an exact answer.)

The initial position has no effect on the velocity, so you can ignore that value (unless there's another part to the question not included, of course).

We have

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
