Item 16
1 answer:
Percentage change in perimeter is 100%.
Step-by-step explanation:
- Step 1: Given length of rectangle 1, length = 5 ft and breadth = 3 ft.
Calculate perimeter of R1 = 2 (length + breadth) = 2 (5 + 3) = 16 ft
- Step 2: Given dimensions of 2nd rectangle is twice the first, length = 10 ft and breadth = 6 ft.
Calculate perimeter of R2 = 2 (10 + 6) = 32 ft
- Step 3: Calculate percentage change using the formula, (R2 - R1/R1)
100
= (32 - 16/16) 100 = 100%

Answer:
(2,6)
Step-by-step explanation:
<u><em>The options of the questions are</em></u>
(0,1) (1,3) (2,6) (3,27)
and the given function is
we know that
If a ordered pair lie on the graph of the given equation, then the ordered pair must satisfy the given equation
<u><em>Verify each ordered pair</em></u>
case 1) (0,1)
substitute the value of x and the value of y in the linear equation and then compare the results
----> is true
so
The ordered pair lie on the graph of the given equation
case 2) (1,3)
substitute the value of x and the value of y in the linear equation and then compare the results
----> is true
so
The ordered pair lie on the graph of the given equation
case 3) (2,6)
substitute the value of x and the value of y in the linear equation and then compare the results
----> is not true
so
The ordered pair not lie on the graph of the given equation
case 4) (3,27)
substitute the value of x and the value of y in the linear equation and then compare the results
----> is true
so
The ordered pair lie on the graph of the given equation
