for this problem we are to evaluate the definite integral from 4 to 4.5 of three over the square root of negative 15 plus eight x minus x squared dx. Now, for the first part we want to determine if long division is necessary in order to simplify the integral. Now, since the integration is not a rational expression, then the long division is not necessary. And now for part B we have to simplify the inter grand. To simplify, we have to apply completing the square to the inside of the squared in the denominator. Now negative 15 plus eight X minus x squared is equal to negative of x squared -8 X -15. That’s negative of x squared minus eight X plus 16 plus one Which becomes 1- the square of X -4. So we can rewrite the integral and…
