Use Laplace transforms to obtain the solution to the following initial value problem: (25 points) Y 00 + 4Y 0 + 4Y = f(t), Y (0) = 2, Y 0 (0) = 4 where f(t) =    t if t < 1 2t − 1 if 1 ≤ t

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.

question

given the diagram below, what is md?

the sum of the interior angles is 360°

take away from 360 the sum of the knows angles and you will have the angle d.

360 - 108 - 108 - 72 = 72°
