Solve the following differential equations using laplace transforms. assume zero initial conditions and that the forcing functions are zero prior to t=0-.a. x(t) +7x (t) =5cos2tb. x(t) + 8 x(t) + 25x (t) =10u (t )

Assume cd | ab are parallel. find m2. a) x= 50° (b) x = 70° c) x = 30° d) x = 60

Type the correct answer in the box. use numerals instead of words. if necessary, use / for the fraction bar.

The area (a) of a circle with a radius of r is given by the formula and its diameter (d) is given by d=2r. arrange the equations in the correct sequence to rewrite the formula for diameter in terms of the area of the circle.
