Question 963426: Adam ran a 15-kilometer race. He completed the race in 1.6 hours. Adam’s speed for the first kilometer can be represented by the function d = 9.2h, where d is distance in kilometers and h is time in hours. Was Adam’s average speed for the first kilometer of the race faster or slower than his average speed for the entire race? Justify your answer.

Question 964150: Please help me, I have done the entire first half but this page is confusing me and I would just like some explaining or examples. Thank you.
Information: Bernard is realizing that his dimensions are not fitting the way that he wants it to because he forgot about the deck. The deck is going to be a rectangular space that borders the pool. Also, for the pool to fit just right, there must be a special product represented when either the area or volume expressions are determined. He wants you to design your own rectangular pool using polynomial expressions, including the deck that borders the pool.
1. Include a diagram or sketch of your pool and deck. Your diagram must have all dimensions represented with polynomials and ensure that a special product will be used.
2. Determine the polynomial expression to represent the area of land space that the pool will cover.
3. Determine the area of the deck that borders the pool based on your dimensions.
I just need help on making this assignment a bit more clear so I can understand it, thank you again.

Question 964233: A student is asked to solve b^2+b^2=c^2 for a and gives the following solution. Assume all variables represent positive Real Numbers.
(Step 1) 
(Step 2) 
(Step 3) b+a=c
(Step 4) a=c-b
Explain the mistake(s) made by the student and provide the correct solution. Make sure to analyze the entire solution as there may be multiple mistakes made.
I cannot figure out the answers to this question. I think I might have the answers but I am not sure they are correct. Any help would be appreciated!

Question 965052: I'm doing negative exponents and they're killing me. I'm trying to understand the concept,especially this certain question. I hope you can help me.
5a^6'b^-9
------------
c^-4'd^5
The answer key has the c^-4 joining the 5 (5c^4) as well as a^-6, b^-9 moving to the denominator with d^5. I hope you can understand this email and explain to me why these exponents moved as they did. .
