Question 26 10 Points If f(x) =1+8x, find f'(@) for a =3 and the equation of the tangent line to f(X) at X = a. A f'(a) = 5 5x - 13 4 ; equation of the tangent line is y= 4 B f'(a) = - -4x + 13 ; equation of the tangent line is y= 5 f'(@) =; equation of the tangent line is y= 4x + 13 5 D f' (a) = - - -5x - 13 AU ; equation of the tangent line is y = 4The position ofa moving particle as a function of time is given by S\") = 13 - t+ 1, where 5 is in meters and t is in seconds. Find the time at which the particle is at rest and the acceleration of the particle at t: 3 5. Time at which the particle is at rest = 2 S ; acceleration of the particle = 2 m/S2 Time at which the particle is at rest = 1 S ; acceleration of the particle = 6m/S2 Time at which the particle is at rest =2 3 ; acceleration of the particle = l m/S2 Time at which the particle is at rest = 3 S ; acceleration of the particle = 3 m/S2
