Let R be the region enclosed by f ( x ) = x 2 + 4 , g ( x ) = ( x − 4 ) 2 and the axes x = 0 and y = 0 . Compute the volume V obtained by rotating R about the x - axis. Hint: Express V as a sum of two integrals.

The variable z is directly proportional to x, and inversely proportional to y. when x is 4 and y is 13, z has the value 1.2307692307692. what is the value of z when x= 9, and y= 20

Monica build a remote control toy airplane for science project to test the plane she launched it from the top of a building the plane travel a horizontal distance of 50 feet before landing on the ground a quadratic function which models the height of the plane in feet relative to the ground at a horizontal distance of x feet from the building is shown
