Suppose the position of an object moving in a straight line is given by s(t) = 3t3 t2 + 8. Find the instantaneous velocity when t = 4. E) The instantaneous velocity is D at t= 4. (Simplify your answer.) Use the formula for instantaneous rate of change, approximating the limit by using smaller and smaller values of h, to nd the instantaneous rate of change for the given function at the given value. f(x)=5)3(; x=3 E) The instantaneous rate of change for the function at x = 3 is El. (Round to three decimal places as needed.) Suppose the position of an object moving in a straight line is given by s(t) = 5t2 - 7t - 9. Find the instantaneous velocity at time t = 2. E> What expression can be used to nd the instantaneous velocity at the given time? . 3(9) - 3(2) A- $3; 97 - 2 33. lim s(b) S( ) b)2 b2 + C. lim 5(9) s(2) b>2 9'2 + 2 D. \"m s(b) SH b)2 b2 The instantaneous velocity at t = 2 is D
