How wide is the hole at ground level on the drawing

8 feet

Step-by-step explanation:

In the given table, given the three point of hole.

Distance from center (x)   Depth from level of ground (y)

                -2                                    -6

                 0                                    -8

                 2                                    -6

The equation of hole form parabolic.

(-2,-6) , (0,-8) and (2,-6)

parabolic equation:

For point (-2,-6)

For point (0,-8)

For point (2,-6)

using the system of equation a, b and c. To solve for a, b and c

4a-2b = 2  and 4a+2b = 2

a=1/2 , b=0, c=-8

Equation:

We need to find wide of hole. Wide hole at ground level where y is 0

So, set y=0 and find distance between x-coordinate

Distance between x-coordinate = 4-(-4) = 8

Hence, The wide of hole is 8 feet

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6
