If you have a graphing calculator set it to radian mode and put these in there.
7/8 miles = 49 / 56 miles so it will take the road crew 49 hours to repave the road.
I think that the angles of the polygon would not change since there isn't a change of the shape, rather it position and rotation. The sum of each internal angle is found using S = 180(n-2), so
S = 180(5-2)
S = 180(3)
S = 540
540 / 5 = 108 degrees.
Therefore, all angles in the polygon is 108 degrees. I think this is what you meant right?
The given function is

And we have to find the value of g(0), and for that we put 0 for x in the given equation.
And on substituting 0 for x in the given expression, we will get


So for the given function, the value of g(0) is -4 .
