Solve the given differential equation (where the function is subject to the given conditions) by using Laplace transforms.y" + y = 4, y
= 2, y' 
= 2
A. y = 6 cos t + 2 sin t + 4 B. y = -2 sin t + 2 cos t + 4 C. y = -2 cos t + 2 sin t + 4 D. y = sin t + 1

Solve the problem.A rumor is spreading across a college campus that there will be no final exams for any classes this semester. At 8 a.m. today, 7 people have heard the rumor. Assume that after each hour, 3 times as many students have heard the rumor. So, for example, 21 people will have heard the rumor by 9 a.m. Let f(t) represent the number of people who have heard the rumor t hours after 8 a.m.i) Find an equation for f.ii) Use f to predict the number of students who will have heard the rumor by 2 p.m.
What will be an ideal response?
