Answer:

Using the quotient rule for part 1: f'(x) = [14x(3-x) - (7x^2)(-1)] / [(3-x)^2] f'(x) = [42x-14x^2 +7x^2] / [(3-x)^2] f'(x) = [42x-7x^2] / [(3-x)^2] Using the chain rule for part 2: g'(x) = -cos(x) * e^(1-sin(x)).

Answer:

g = -9.8 m/s^2 v_f = 0 m/s y = 0.6 m v_i = ? t = ? To find initial velocity: v_f^2 = v_i^2 + 2*g*y 0^2 = v_i^2 + (2 * -9.8 * 0.6) 0 = v_i^2 - 11.76 v_i^2 = 11.76 v_i = 3.4 m/s To find time spent in the air: v_f = v_i + a*t 0 = 3.4 + (-9.8)*t -3.4 = -9.8*t t = 0.35 s
