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. Write an equation Expressing the velocity, V, in terms of the number of seconds, t. Use this function to predict the Velocity of the object at time t = 7.7 seconds.
A)257.7 feet per second
B)255.4 feet per second
C)256.4 feet per second
D)254.4 feet per second

The equation for velocity is V = 32t + 10. Substituting t = 7.7, we get V = 32(7.7) + 10 = 246.4 + 10 = 256.4 feet per second.
