To calculate:What are the important points on the graph?
Answer to Problem 4STP
Explanation of Solution
Given information:For the race you swim 1 mile, run 10 miles, and bike 25 miles
Calculation:
In the graph the slope of the line is speed of swimming or running or biking.
First, we swim for 1 mile, during the swimming speed is very slow as compare to running and biking. Hence the slope of the line during swimming will be least as compare to running and biking.
Now we run for 10 miles, during the running speed is slow as compare to biking and speed is faster as compare to swimming. Hence the slope of the line during running will be less as compare to biking and will be more as compare to the swimming.
Lastly, we bike for 25 miles, during the biking speed is very fastas compare to running and swimming. Hence the slope of the line during biking will be mostas compare to running and swimming.
Here OA represents the slop of speed of swimming
and AB represents the slop of speed of running
and BC represents the slop of speed of biking.
The important points in the graph are O,A,B and D.

- Compare the interest earned from #1 (where simple interest was used) to #5 (where compound interest was used). The principal, annual interest rate, and time were all the same; the only difference was that for #5, interest was compounded quarterly. Does the difference in interest earned make sense? Select one of the following statements. a. No, because more money should have been earned through simple interest than compound interest. b. Yes, because more money was earned through simple interest. For simple interest you earn interest on interest, not just on the amount of principal. c. No, because more money was earned through simple interest. For simple interest you earn interest on interest, not just on the amount of principal. d. Yes, because more money was earned when compounded quarterly. For compound interest you earn interest on interest, not just on the amount of principal.arrow_forwardCompare and contrast the simple and compound interest formulas. Which one of the following statements is correct? a. Simple interest and compound interest formulas both yield principal plus interest, so you must subtract the principal to get the amount of interest. b. Simple interest formula yields principal plus interest, so you must subtract the principal to get the amount of interest; Compound interest formula yields only interest, which you must add to the principal to get the final amount. c. Simple interest formula yields only interest, which you must add to the principal to get the final amount; Compound interest formula yields principal plus interest, so you must subtract the principal to get the amount of interest. d. Simple interest and compound interest formulas both yield only interest, which you must add to the principal to get the final amount.arrow_forwardSara would like to go on a vacation in 5 years and she expects her total costs to be $3000.
