Hello, i am learning that i need to show all work finding and simplifying the derivative.

• If you use the quadratic formula to solve S '(t) = 0, you do not need to show a lot of detail.

If you could please answer question c with a sentence.

• In question d: suppose your answer is 5.67, do not write 5.67 thousands of dollars.please write $5,670.
• Make sure your graph is only on the interval 0
• THANKYOU

Every assignment must be typed and a sufficient amount of work shown. Graphs must be done electronically (I do not want hand drawn graphs.) Directions for graphing using excel are available in blackboard. You may ask for help with the assignments. 1.
