disposable income is the amount left after taxes have been paid and is one measure of health of the economy. The total disposable for a country, in billions of dollars, for selected years from 2010 and projected to 2040. Find the linear model that models the data, where x is the numbers of years after 2000 and y is the total disposable income in billions of dollars.

Solve the equation -9p - 17 =10 a -3 b. 16 c. 18 d -16

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)
