5 pts 1) find the length of the curve. 5 pts 2) find the area of the surface obtained by rotating the curve about the x-axis. 5 pts 3) find the solution of the differential equation. Solve for y explicitly for full credit. ( 2 x. + )1 xy dy dx that satisfies the initial. 5 pts 4) a bacteria culture grows at a rate of dp = 5 pts 5) a function y(t) satisfies the differential equation. 2 dy dt: find and plot equilibrium points, determine whether equilibrium points are stable or unstable (or perhaps something else).
