A weight is suspended on a spring and set in motion such that it bobs up and down vertically. The equation h(t) = 2cos(3pi(t)) + 3 can be used to represent the height, h, in centimeters, of the weight above a desk after time, t, in seconds. Determine the instantaneous rate of change of the height at t = 6.5 seconds. Round your answer correct to two decimal places. Enter values such as: 0.02, 4.00, 5.30, 9.24 Your Answer: AnswerWhich inequality has x -4 or 0 Sx$3 as its solution? a) x(x - 3) (x + 4) 50 O b) - 2x( x - 3 ) (x + 4) 20 O c) 10 0x (x - 3 ) (x + 4) 50 O d) all of the aboveBelow are a number of polynomial functions.

Suppose a passenger boards the Ferris wheel at the lowest point which is 3 m above the ground. If the ride begins once this passenger boards the lowest car, determine the time at which this passenger's height above the ground first reaches 10 m. Round your answer correct to two decimal places.
