The acceleration function (in m/s) and the initial velocity are given for a particle moving along a line a(t)= t+4, v(0)=4, 0 is less than or equal to t less than or equal 11

(A) find the velocity at time t

(B) find the distance traveled during the given time interval

Suppose that the price p (in dollars) and the weekly sales x (in thousands of units) of a certain commodity satisfy the demand equation 4p cubedplusx squaredequals38 comma 400. determine the rate at which sales are changing at a time when xequals80, pequals20, and the price is falling at the rate of $.20 per week.

Ineed to know the answer right now! !
