a.
To calculate the distance between Isadorra’s home and school
a.
Answer to Problem 3.1STP
I’s home is 1200 yards away from her school.
Explanation of Solution
Given:
Graph of relation between time and distance
Concept Used: Graph reading
Calculation:
The starting point on the graph, that is, where value of time is zero, shows the total distance Issadorra has to travel.
Hence, concluding from the graph, the distance between I’s home and school is,
1200 yards.
Conclusion:
The distance between I’s school and home is 1200 yards.
b.
To calculate the distance Issadora is at, from home, after travelling for 3mins.
b.
Answer to Problem 3.1STP
She is 1000 yards away from her home, after travelling for 3mins.
Explanation of Solution
Given:
Graph of relation between time and distance
Concept Used:
Graph reading
Calculation:
Checking the value of distance when time is 3mins,on the graph.
Hence, concluding from the graph, the distance between I’s home and school is,
1000 yards, when she has been travelling for 3 min.
Conclusion:She is 1000 yards away from her home, after travelling for 3mins.
c.
To calculate the time when Iis 200 yards from her home
c.
Answer to Problem 3.1STP
After 10 mins of walking, I was 200 yards from home.
Explanation of Solution
Given:
Graph of relation between time and distance
Concept Used: Graph reading
Calculation:
Checking the value of time when distance is 200yards, on the graph.
Hence, concluding from the graph, the time I’s was travelling for when distance was 200 yards, from her home is, 10 mins.
Conclusion:
After 10 mins of walking, I was 200 yards from home.
d.
To calculate time it took I to reach home.
d.
Answer to Problem 3.1STP
She is 1000 yards away from her home, after travelling for 3mins.
Explanation of Solution
Given:
Graph of relation between time and distance
Concept Used:
Graph reading
Calculation:
The ending point on the graph, that is, where value of distance is zero, shows the total time it took Issadorra to reach home.
Hence, concluding from the graph, the total time it took I’s to reach home from school is,
12mins.
Conclusion: She is 1000 yards away from her home, after travelling for 3mins.

- 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.

How many vectors are in {a₁, a₂, a3}? b. Is b in W? How many vectors are in W? c. Show that a2 is in W. [Hint: Row operations are unnecessary.] a. Is b in {a₁, a2, a3}? Select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice. ○ A. No, b is not in {a₁, a2, 3} since it cannot be generated by a linear combination of a₁, a2, and a3. B. No, b is not in (a1, a2, a3} since b is not equal to a₁, a2, or a3. C. Yes, b is in (a1, a2, a3} since b = a (Type a whole number.) D. Yes, b is in (a1, a2, 3} since, although b is not equal to a₁, a2, or a3, it can be expressed as a linear combination of them.
