I am lost on what to do. I've tried to list what I know, but I got confused and have no leads. I'm working on Problem 3. Pleases help and show steps how to work out problem.
Find the first and second derivatives of the function. Please out the answer in a box. 3.3
Please show detailed step-by-step explanation and solution for each problem (problem #2, problem #3, problem #4, problem #5, and problem #6). Please use the results of problems #2 and problems #3 to solve and show your work for problems #5 and problems #6 (just like the hint stated).
Please help on both of these questions
I need formula for this problem
Please solve the last 3 problems, I just submitted and have solution to the first 3 problems .
Dear tutor, please help me solve this calculas question
This question has several parts that must be completed sequentially. If you skip a part of the question, you will not receive any points for the skipped part, and you will not be able to come back to the skipped part. A person's lean body weight L is the amount he or she would weigh if all body fat were magically to disappear. One text gives the "equation that practitioners can use most feasibly in the field to predict lean body weight in young adult males." The equation is found below. L = 98.42 + 1.08W − 4.14A Here L is lean body weight in pounds, W is weight in pounds, and A is abdominal circumference in inches. Find the approximate lean body weight of a young adult male who weighs 181 pounds and has an abdominal circumference of 41 inches. What is the weight of his body fat? What is his body fat percent?
how did you get the new equations in last part of step 2?
please solve this with clear text, as the last solution was not clear, also with full detail as well
Please help on all the parts of the problem!!
A termite lives in the very middle of a large cube divided into 27 small cubes. It has always dreamed of discovering the entire cube by taking an awesome journey. Since it does not want to be bored during the journey, it wants to visit all small cubes exactly once. It can go into a new small cube if the new and the current one share a face. Can its desire be fulfilled?
