28. Find the equation of the tangent to the curve f(x) = |x - 2x 2 (3x + 5x2 ) at the point (1, 4). 29. Find the equation of the tangent to the curve y = 2 sinx + sin x at the point where x = 30. The horizontal position of the pendulum of a grandfather clock can be modelled by h(1) = Acos( 2,! ). where A is the amplitude of the pendulum, t is time, in seconds, and 7 is the period of the pendulum. Determine the formula for the velocity of the pendulum at time t. Problem 31. Determine the equation of the tangent to f(x) = 3x + 5x + 2 at the point (1, 10). 32. In a ski resort town, the number of people employed, p(), during any given month, , can be modelled by the in ( = ( + 1) | + 50 . function p(t) = 2300 sin - (t+ 1) +5500, where I S t S 12 and t = 1 represents January, t = 2 represents February, etc. Determine the maximum and minimum number of people employed during the year and in which month they occur
