Reminder Round all answers to two decimal places unless otherwise indicated.
Note Some of the formulas below use the special number
V, in feet per second, is a function of the time t, in seconds, since the ball was thrown. The formula is
if we ignore air resistance. The function V is positive when the ball is rising and negative when the ball is falling.

- A forest fire leaves behind an area of grass burned in an expanding circular pattern. If the radius of the circle of burning grass is increasing with time according to the formula r(t)=2t+1 , express the area burned as a function of time, t (minutes).arrow_forwardUse a calculator to help solve each problem. Alcohol absorption In one individual, the percent of alcohol absorbed into the bloodstream after drinking two glasses of wine is given by the following formula. Find the percent of alcohol absorbed into the blood after 12 hour. Pt=0.31-e-0.05t where, t is in minutesarrow_forwardThe height h of a projectile is a function of the time t it is in die air. The height in feet for t seconds is given by the function h(t)=-16t2+96t . What is the domain of die function? What does the domain mean in the context of die problem?arrow_forward
