Andrew has a cellphone plan that provides 300 free minutes each month for a flat rate of $19.for any minutes over 300,andrew is charged $0.9 per minute. which of the following piecewise functions represents changes based on andrews cellphone plan? (a) f(x)=19,x> 300 over 19+39x, x300 (c) f(x)=19,x< =300 over 19+39(x-300),x> 300 (d) fx= 19,x< =300 over 39x, x> 300

The constitution gives congress the power to create federal courts lower than the supreme court higher than the supreme court equal to the supreme court, unaffected by the supreme court.

Find an bif a = {3, 6, 9, 12) and b = {2, 4, 6, 8, 10).

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)
