a? a? Rate and Accumulation Balloon Worksheet V(t) is a function that gives the volume of a ballon in cubic centimeter (cm3) as it is being inated, where t measures the amount of time in seconds that have passed since starting to inate the balloon. 1 3 7,,(t) : (4t) gives the rate of change of the volume with respect to time, in cma/sec, and is valid for tin the interval [0.15]. We will investigate the balloon's volume. 1r 1) Using numerical computations in one interval... a) What is the rate at which the balloon is being inated at the moment t = 3.8? rV(3.8) = 0.968
