(a)
Whether the statement is true of false
(a)
Answer to Problem 26HP
True
Explanation of Solution
Given:
Area of larger rectangle = Sum of area of smaller rectangles made up of larger rectangles
Calculation:
This statement is true because the sum of the areas of smaller rectangles made up from the larger rectangle is equal to the area of the larger rectangles
Consider a rectangular park having length = 20m and width = 10m
Suppose this park is divided into two parts A and B with dimensions as
A: length = 10m, width = 10m
B: length = 10m, width = 10m
The area of bigger rectangle will be
The area of rectangle A will be
The area of rectangle B will be
Hence,
(b)
Whether the statement is true of false
(b)
Answer to Problem 26HP
False
Explanation of Solution
Given:
Perimeter of larger rectangle = Sum of perimeters of smaller rectangles made up of larger rectangle
Calculation:
This statement is false because the sum of the perimeters of smaller rectangles made up from the larger rectangle is not equal to the perimeter of the larger rectangle
Consider a rectangular park having length = 20m and width = 10m
Suppose this park is divided into two parts A and B with dimensions as
A: length = 10m, width = 10m
B: length = 10m, width = 10m
The perimeter of bigger rectangle will be
The perimeter of rectangle A will be
The perimeter of rectangle B will be
Hence,

- I've been struggling with this because of how close the numbers are together!! I would really appreciate if someone could help me❤️arrow_forwardMatrix MЄ R4×4, as specified below, is an orthogonal matrix - thus, it fulfills MTM = I. M (ELES),- m2,1. We know also that all the six unknowns mr,c are non-negative with the exception of Your first task is to find the values of all the six unknowns. Think first, which of the mr,c you should find first. Next, consider a vector v = (-6, 0, 0, 8) T. What's the length of v, i.e., |v|? Using M as transformation matrix, map v onto w by w = Mv provide w with its numeric values. What's the length of w, especially when comparing it to the length of v? Finally, consider another vector p = ( 0, 0, 8, 6) T. What's the angle between v (from above) and p? Using M as transformation matrix, map p onto q by q = Mp - provide q with its numeric values. What's the angle between w and q, especially when comparing it to the angle between v and p?arrow_forward7. (a) (i) Express y=-x²-7x-15 in the form y = −(x+p)²+q. (ii) Hence, sketch the graph of y=-x²-7x-15. (b) (i) Express y = x² - 3x + 4 in the form y = (x − p)²+q. (ii) Hence, sketch the graph of y = x² - 3x + 4. 28 CHAPTER 1arrow_forward
- Part 1 and 2arrow_forwardWhat is the distance between 0,0 and 2,0 aarrow_forwardCompare 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_forward
- Compare 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. If she invests $2500 into a savings account for those 5 years at 8% interest, compounding semi-annually, how much money will she have? Round your answer to the nearest cent. Show you work. Will she be able to go on vacation? Why or why not?arrow_forwardIf $8000 is deposited into an account earning simple interest at an annual interest rate of 4% for 10 years, howmuch interest was earned? Show you work.arrow_forward
