You can model the entrance to a mine shaft using the equation y = − 2 (x + 4)(x − 4), where x and y are measured in feet. the x-axis represents the ground. find the width of the entrance at ground level. need quick all points at risk 99 points quick

y=-1/2 2 (x+4)(x+-4+

-1/2*2 = -1

y=-1(x+4)(x-4)

solving for x

x - -4 and x =4

-4 to 4 = 8 feet

 width = 8 feet

only 10/60 isn't equivalent

hope this : )

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two
