Students in a marine biology program built underwater drones. The students were split into two groups, and each group designed and built its own drone. During a recent round of testing, they modeled the path of each drone using these
functions, where x is the horizontal distance from the launch site, in miles, and d(x) is the depth below the surface of the
water, in meters.
Voyager: d(2) = 0.25(x – 35)2 – 225
Pioneer: d(x) = 0.3(x – 32)2
- 270
Use the custom button to graph the functions and determine the depth of each drone at its lowest point.

Which is the standard form for this number? (4 x 1 100 ) + (8 x 1 1,000 ) + ( 3 x 1 100,000 ) ? a) 0.004803 b) 0.04803 c) 0.0483 d) 0.483

You drop a rubber ball off the roof of a 50 meter high building onto a paved parking lot. it bounces back up with every bounce, but not quite all the way back up to you. after the first bounce it bounces back only 80 percent of the distance it was dropped from. the pattern continues, meaning after every bounce it comes up to just 80 percent of the previous maximum height. so if before the first bounce the height is 50 meters, what height does the ball reach after the fifth bounce? round your answer to one decimal place and chose the correct response from the choices below:

A. 127 cm^2 b. 144.5 cm^2 c. 172 cm^2 d. 50 cm^2
