1- The radius r, in inches, of a spherical balloon is related to the volume, V, by r(V)=33V4. Air is pumped into the balloon, so the volume after t seconds is given by V(t)=15+15t. a. Find the composite function: r(V(t))= b. Find the exact time when the radius reaches 5 inches. seconds

2-ind the domain, vertical asymptotes, and horizontal asymptotes of the function. f(x)=24x3 Domain: {xx } Vertical asymptote at x= Horizontal asymptote at y
