The height and weight of several adults were recorded:
Height (ft)
4.65
5.15
5.6
5.85
6.2
6.35
Weight (lbs)
95.9
118
141
151
167
186
It was discovered that this can be modeled by the equation
y = 50.2x−140
where x is height in feet and y is weight in pounds.
What height corresponds to a weight of 130 pounds? Round to the nearest hundredth.
A 6.25 ft B 5.85 ft C 6.68ft D 5.38 FT

Aswimming pool has an input pump for filling the pool and an output pump for emptying the pool. the input pump can fill the pool in 3 hours, and the output pump can drain the pool in 5 hours. as you go to bed, the pool is full, but a neighbor’s kid turns on the output pump. at midnight, you awake to find the pool half empty. immediately, you turn on the input pump, but you are sleepy and forget to turn off the output pump. at what time will the pool become full?

Find the vertex of the function given below y=x^2-6x+1
