Given:
maximum seating 76,867 fans
cost of tickets $161
revenue: f(x) = 161x
y = 161x
domain is the x values
range is the y values
using the formula: y = 161x where x = 76,867
y = 161(76,867)
y = 12,375,587
domain is 76,867
range is 12,375,587
John can walk 4 miles per hour
$736 because $184 x 4 would give you your amount.
The intersecting secant-tangent theorem says that

where T is the point at which line segment PO touches the circle. Similarly,

so we have

OP is of course as long as itself, and AO and BO are radii of the same circle so they have the same lengths.
This means triangles APO and BPO are congruent, which means angles APO and BPO are congruent, so angle APB is bisected by PO.
