* Fishing spiders can propel themselves across water and leap vertically from the surface of the water.
During a vertical jump, the height of the body of the spider can be modeled by the function
y=-4500x2 + 820x + 43, where x is the time, in seconds, of the jump and y is the height, in
millimeters, of the spider above the surface of the water.
1. After how many seconds does the spider's body reach it maximum height?
