The surface of a pedestrian bridge forms a parabola. Let the surface at one side of the bridge be represented by (4,0) and the surface of the other side be represented by (8,0). The center of the bridge is 3 feet higher than each side and can be represented by a vertex of (6,3). Write a function in vertex form that models the surface of the bridge

Acompany produces packets of soap powder labeled “giant size 32 ounces.” the actual weight of soap powder in such a box has a normal distribution with a mean of 33 oz and a standard deviation of 0.7 oz. to avoid having dissatisfied customers, the company says a box of soap is considered underweight if it weighs less than 32 oz. to avoid losing money, it labels the top 5% (the heaviest 5%) overweight. how heavy does a box have to be for it to be labeled overweight?
