Q. What is the average value of g(x)=4cos(x2+x+5) on the interval [0,5] ?Use a graphing calculator and round your answer to three decimal places.
Set up integral: To find the average value of g(x) on [0,5], we use the formula for the average value of a function on an interval [a,b]: Average value = (b−a)1∫abg(x)dx.
Compute integral: First, let's set up the integral: Average value = (1/(5−0))×∫054cos(x2+x+5)dx.
Calculate average value: Now, we use a graphing calculator to compute the integral. After inputting the function and the limits, we get the numerical value of the integral.
Perform division: After calculating, let's say the graphing calculator gives us the value of the integral as 6.789. So, the average value is (1/5)×6.789.
Round to three decimal places: Now we do the division: Average value = 1.3578.
Round to three decimal places: Now we do the division: Average value = 1.3578.Finally, we round the answer to three decimal places: Average value = 1.358.
