a skateboard halfpipe is being designed for a competition the halfpioe wilm be in the shape of a parabola and will be oisituoned aboce the fround shch that its focus is 30 ft above the ground using the ground as the x ashx ehere should the base iof the halfpioe be positioned 0 60

5x+2x=49

7x=49

x=7. 35 apples

step-by-step explanation:

secant-secant formula:

(whole secant) x (external part) =           (whole secant) x (external part)

(8+y-2) *8=                                           (y+4+6) *6

(y+6)*8 = (y+10) *6

distribute

8y+48 = 6y +60

subtract 6y from each side

2y +48 = 60

subtract 48 from each side

2y = 12

divide by 2

y = 6

sv =     (y+4+6)

sv   = 6+4+6

sv = 16
