An object moves clockwise around a circle centered at the origin with radius 5 m beginning at the point (0,5). a. Find a posit
ion function r that describes the motion of the object moves with a constant speed, completing 1 lap every 8 s. b. Find a position function r that describes the motion if it occurs with speed e Superscript negative t.
C=1500+4x where x is cds, C is cost R=10x where R is revenue then, P=R-C P=10x-1500-4x P=6x-1500 set P=0 1500=6x x=250 check, C=1500+4*250, R=10*250 C=250, R=250 They need to sell 250 cds before they make profit
