Solve the problem.If an object is dropped from a tower, then the velocity, V (in feet per second), of the object after t seconds can be obtained by multiplying t by 32 and adding 10 to the result. Find V as a linear function of t, and use this function to evaluate V(7.9), the velocity of the object at time 
A. V(7.9) = 264.1 feet per second B. V(7.9) = 262.8 feet per second C. V(7.9) = 262.1 feet per second D. V(7.9) = 260.8 feet per second
