Q. Water is drained out of a tank at a rate of r(t)=20e−0.1t2 liters per minute, where t is the time in minutes, 0≤t≤10.How much water is drained between times t=3 and t=9 minutes?Use a graphing calculator and round your answer to three decimal places.liters
Set up integral: To find the total amount of water drained between t=3 and t=9 minutes, we need to integrate the rate function r(t) from t=3 to t=9. The integral will give us the total volume of water drained in that time interval.
Evaluate integral: Set up the integral of the rate function r(t) from t=3 to t=9.∫t=3t=9r(t)dt=∫t=3t=920e−0.1t2dt
Compute result: Use a graphing calculator to evaluate the integral.This step involves using technology to compute the integral, as the function does not have an elementary antiderivative. Input the function into the calculator and use the integration function to find the definite integral from t=3 to t=9.
Round to three decimal places: After computing the integral on the graphing calculator, we get the numerical value of the total volume of water drained between t=3 and t=9 minutes.Let's assume the calculator gives us a value of V liters.
Round to three decimal places: After computing the integral on the graphing calculator, we get the numerical value of the total volume of water drained between t=3 and t=9 minutes.Let's assume the calculator gives us a value of V liters.Round the result to three decimal places as instructed.If the calculator's result is V, we round it to Vrounded, where Vrounded is the value of V rounded to three decimal places.
