Let r be the region in the first quadrant enclosed by the graph y=(square root(6x+ the line y=2x, and the y-axis. . a. find the area of r.. b. set up but do not integrate an integral, expression in terms of a single variable for the volume of the solid generated when r is revolved about the x-axis .. c. do the same as part b, just this time the y-axis.

What is the equation in point slope form of the line that passes through the point (-1, -3) and has a slope of 4? y-1=4(x-3) or y+3=4(x+1)

Marcus needs to rewrite f(x) = x2 + 6x + 4 in vertex form.

Suppose you just purchased a digital music player and have put 8 tracks on it. after listening to them you decide that you like 4 of the songs. with the random feature on your player, each of the 8 songs is played once in random order. find the probability that among the first two songs played (a) you like both of them. would this be unusual? (b) you like neither of them. (c) you like exactly one of them. (d) redo () if a song can be replayed before all 8 songs are played.
