8. A spring with spring constant 8 Newtons/meter is hung from the ceiling. A mass of 2 kg. is attached to that spring, and a dashpot with damping coefficient 8 is connected to the mass. 1. Find the differential equation determined by this system. Is the system overdamped, underdamped, or critically damped? 2. At $t = 0$ the mass is pushed up to a distance of 1 m from equilibrium, hooked up to a motor which pushes the spring up and down with an external force of 16 cos(2$t$) Newtons, and released (with initial velocity 0). Find the position of the mass at time $t$.

In college football there are many plays that can be reviewed by the replay official in an effort to insure that correct call is made. A review may be initiated by a coaches challenge or by the replay official and there are three possible outcomes of a review. The call on the field may be \"overturned\", \"confirmed\", or \"stand\" meaning that there was not enough evidence to overturn the call nor to confirm the call. The table below indicates who initiated a review and the result for 2328 replay reviews. is overturned is confirmed stands Total a coaches challenge 340 288 648 1276 the replay booth 326 422 304 1052 Total 666 710 952 2328 (Round all answers to 5 decimal places) A. Three replay reviews are randomly selected with replacement, what is the probability that every call is confirmed? B. Three different replay reviews are randomly selected, what is the probability that every call is confirmed?

Pope Company produces a model fan, which currently has a net loss. Below are its sales and costs Sales revenue Less: Variable costs Contribution margin Less: Direct fixed costs Segment margin Less: Common fixed costs Net operating income (loss) $125,598 61,620 $7 46,462 $7 57,488 $7 Eliminating the model fan product line would eliminate all of direct fixed costs. All of the common fixed costs would be redistributed to Pope's remaining product lines. By how much will Pope's net operating income increase or decrease if the fan is eliminated? If net income decreases, indicate with a -. Example, if net income decreases $1,000, indicate 1,000.
