A ball fell for 20 seconds at a rate of 10 feet per second. A second ball fell for 2x less seconds at a rate of speed that is x feet per second slower than the first ball.

Which of the following equations could be used to determine how far the second ball fell?

A. y = (2x^2 - 40x + 200) ft

B. y = (2x^2 - 12x + 30) ft

C. y = (-2x^2 + 200) ft

D. y = (-2x^2 + 30) ft

The solution set for 5v2 – 125 = 0 is

Given: ∆mop p∆mop =12+4 3 m∠p = 90°, m∠m = 60° find: mp, mo

Sketch the vector field vector f( vector r ) = 8vector r in the xy-plane. select all that apply. the length of each vector is 8. the lengths of the vectors decrease as you move away from the origin. all the vectors point away from the origin. all the vectors point in the same direction. all the vectors point towards the origin. the lengths of the vectors increase as you move away from the origin.
