Ido not understand this integration problem. i understand why they made u, du, and dx what they did, no problems. but isnt the integral of (u+1)/2 * u^(1/2) du/2
equal 1/4 integral u * u^(1/2)? i do not understand where the second line comes from with the u^(3/2)+u^(1/2).

Arefrigeration system at your company uses temperature sensors fixed to read celsius (°c) values, but the system operators in your control room understand only the fahrenheit scale. you have been asked to make a fahrenheit (°f) label for the high temperature alarm, which is set to ring whenever the system temperature rises above –10°c. what fahrenheit value should you write on the label?
