4. suppose a copy machine is set to reduce a picture that's 8.5 inches by 11 inches to picture dimensions one-half the original size. what proportion shows this reduction? a. 8.5⁄11 = 5.5⁄4.25 b. 8.5⁄11 = 17⁄22 c. 8.5⁄11 = 2.125⁄2.75 d. 8.5⁄11 = 4.25⁄5.5

An architect is designing a water fountain for a park she uses the given function to model the water jet flowing from the fountain nozzles where h(x) gives the height of the water jugs in feet x feet from the starting point h(x)=-1/20x+x+15

Place the following steps in order to complete the square and solve the quadratic equation,

Aball is thrown from a height of 139 feet with an initial downward velocity of 15 ft/s. the ball's height h (in feet) after t seconds is given by the following. h=139-15t-16t^2 how long after the ball is thrown does it hit the ground? round your answer(s) to the nearest hundredth. (if there is more than one answer, use the "or" button.) t =
