Find the volume of the solid by the method of slicing if cross sections are a) squares b) semicircles and c)equilateral triangles and perpendicular to the x axis The base of a solid is the region bounded by the graphs of y=3*sqrt(3x) and =^2 . Present an exact answer, using fractions if needed.

Answer this 30 points and brainliest!

There are 15 plates and each plate is either 7 or 12 inches diameter. which systems of equations do you use to find the number of 7 inch plates, x and 12 inch plates, y

Determine whether the points (–3,–6) and (2,–8) are in the solution set of the system of inequalities below. x ? –3 y < 5? 3x + 2 a. the point (–3,–6) is not in the solution set, and the point (2,–8) is in the solution set. b. neither of the points is in the solution set. c. the point (–3,–6) is in the solution set, and the point (2,–8) is not in the solution set. d. both points are in the solution set.
