Simonne has been following the stock ratings of Carter's Pork Bellies. She has noticed that the pattern can be modeled by a cosine function. During her observations, she has found the stock to have a maximum of x = 6, minimum of x = −2, and period of π. Which of the following cosine functions could model Simonne's stock rating?a. f(x) = 4 cos 2x − 4b. f(x) = 6 cos pi over 2 x + 2c. f(x) = 6 cos pi over 2 x − 4d. f(x) = 4 cos 2x + 2

Frank is having a raised rectangular platform built. He designed it so that the length of the platform is 4 feet longer than the width, w, and the height, h, of the platform is 10 feet less than the width of the platform. The cost of the raised platform will be based on its top area and its height. The cost of the raised platform is $8 per square foot of the top area plus $4 per foot of the height, for a total cost of $1,544. Create a system of equations to model the situation above. Determine the solutions and if the solutions are viable. If there is one viable solution, fill in the values below for the width, length, and height of the raised platform. If there is more than one viable solution, choose the solution with the smallest width, and fill in the values below for the width, length, and height of the raised platform. If there is no viable solution, fill in each blank with the word "no".
