Here is the question:Here f(x)=3x^2 shown on a table. To see the graph use desmos. What interval is the function increasing over?What interval is the function decreasing over? Explain how to determine the increasing or decreasing intervals on both the table and the graph

Simplify a7/a4 a) 1/a3 b)-a/a2 c)a4/a3 d)a3

Need so much on this one how many yards?

For every corresponding pair of cross sections, the area of the cross section of a sphere with radius r is equal to the area of the cross section of a cylinder with radius and height 2r minus the volume of two cones, each with a radius and height of r. a cross section of the sphere is and a cross section of the cylinder minus the cones, taken parallel to the base of cylinder, is the volume of the cylinder with radius r and height 2r is and the volume of each cone with radius r and height r is 1/3 pie r^3. so the volume of the cylinder minus the two cones is therefore, the volume of the cylinder is 4/3pie r^3 by cavalieri's principle. (fill in options are: r/2- r- 2r- an annulus- a circle -1/3pier^3- 2/3pier^3- 4/3pier^3- 5/3pier^3- 2pier^3- 4pier^3)
