Mathematical processes are the steps used to determine the result of operations
- The perimeter of the rectangle is
- The area of the rectangle is
The dimension of the rectangle is given as:
<u>(1) The perimeter of the triangle</u>
This is the sum of the side lengths of the rectangle.
So, we have:
This gives
Collect like terms
Open brackets
Hence, the perimeter of the rectangle is
<u>(2) The area of the triangle</u>
This is the product of the dimensions of the rectangle.
So, we have:
This gives
Open brackets
Collect like terms
Hence, the area of the rectangle is

Answer:
yea that makes sense
It literally tells you how to do it
Is it some kind of proof tho? Like the math makes sense but like I've never heard of this thing.
According to the model, the year will the population exceed 470 million is 2060
What is the first step to take?
The first step in this case is to use the model to compute the population figure in each year as shown below:
N = 3.21t + 277.3
Year 2020:
t=20
N = 3.21(20) + 277.3
N=341.50
Year 2025:
t=25
N = 3.21(25) + 277.3
N= 357.55
Year 2030:
t=30
N = 3.21(30) + 277.3
N=373.60
Year 2035:
t=35
N = 3.21(35) + 277.3
N= 389.65
Year 2060:
t=60
N = 3.21(60)+ 277.3
N= 469.90
Year 2065:
t=65
N = 3.21(65)+ 277.3
N= 485.95
Since all the years given do not give the correct year, let us equate the target population figure to the model and solve for t
470= 3.21t + 277.3
470-277.3=3.21t
192.70=3.21t
t=192.70/3.21
t=60.03(approximately 2060)
