Consider a vibrating string of length L = π that satisfies the wave equation
4∂2u = ∂2u, 00. ∂x2 ∂t2
Assume that the ends of the string are fixed, and that the string is set in motion with no initial velocity from the initial position
u(x, 0) = 12 sin 2x − 16 sin 5x + 24 sin 6x. Find the displacement u(x, t) of the string.

A. plot the data for the functions f(x) and g(x) on a grid and connect the points. x -2 -1 0 1 2 f(x) 1/9 1/3 1 3 9 x -2 -1 0 1 2 g(x) -4 -2 0 2 4 b. which function could be described as exponential and which as linear? explain. c. if the functions continue with the same pattern, will the function values ever be equal? if so, give estimates for the value of x that will make the function values equals. if not, explain why the function values will never be equal.

Amajor grocery store chain is trying to cut down on waste. currently, they get peaches from two different distributors, whole fruits and green grocer. out of a two large shipments, the manager randomly selects items from both suppliers and counts the number of items that are not sell-able due to bruising, disease or other problems. she then makes a confidence interval. is there a significant difference in the quality of the peaches between the two distributors? 95% ci for pw-pg: (0.064, 0.156)
