Verify that the given functions y1 and y2 satisfy the corresponding homogeneous equation; then find a particular solution of the given nonhomogeneous equation.

ty'' − (1 + t)y' + y = t2e2t, t > 0; y1(t) = 1 + t, y2(t) = et

what is the approximate angle of acb if abc is 25cm and the length of segment bc is 15

step-by-step explanation:

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
