At the skateboard park, the hot new attraction is the U-Dip, a cement structure embedded into the ground. The cross-sectional view of the U-Dip is a parabola
that dips 15 feet below the ground. The width at ground level, its widest part,
is 40 feet across. Sketch the cross-sectional view of the U-Dip, and find an
equation of the parabola that models it.

(-1,0) and (4,0) are x-intercepts.

step-by-step explanation:

x-intercepts are all points on the x-axis.

points (-1,0) and (4,0) are both x -intercepts.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

17

step-by-step explanation:

51/3=17

thus 17 is your answer.
