a. The circumference of the yellow circle is 43.96 ft.
b. The circumference of the purple circle is 28.26 ft.
What is the circumference of a circle?A circle is a figure that is bounded by a curved path called circumference. Thus a circumference if the boundary of a given circle. It can be determined by;
circumference of a circle = 2πr
where r is the radius of the circle.
In the diagram given in the question, we have;
a. diameter of the purple circle = 9 ft, so that;
r = d/2
= 9/2 = 4.5 ft
Circumference of the purple circle = 2πr
= 2*3.14*4.5
= 28.26
Circumference of the purple circle is 28.26 ft.
b. diameter of the yellow circle = 2.5 + 9 + 2.5
= 14
So that;
r = d/2
= 14/2 = 7 ft
Circumference of the yellow circle = 2πr
= 2*3.14*7
= 43.96
The circumference of the yellow circle is 43.96 ft.

Find an equation for the line below.
Answer: [tex]y = \frac{1}{2}x + \frac{1}{2}[/tex]
Step-by-step explanation:
Step 1: Find the slope using the two points given
[tex](3,2)[/tex]and [tex]-(5,-2)[/tex]
use the slope formula ->[tex]slope = \frac{y2 - y1}{x2 - x1}[/tex]
[tex]= \frac{-2-2}{-5 - 3}[/tex]
[tex]= \frac{-4}{-8}[/tex]
[tex]= \frac{1}{2}[/tex]
Plug in the slope into the slope-intercept form -> [tex]y = mx + b[/tex]
[tex]y = \frac{1}{2}x + b[/tex]
Step 2: Find the y-intercept (also known as b in the formula above):
Do this by taking any point (3,2) or (-5,-2) and plugging it into the slope equation in Step #1
[tex](3,2)\\y = \frac{1}{2}x + b\\2 = \frac{1}{2}(3) + b\\2 = \frac{3}{2} + b\\4 = 3 + 2b\\1 = 2b\\b = \frac{1}{2}[/tex]
Step 3: Plug in the slope we found in step 1 and the y intercept in step 2
[tex]y = mx + b\\y = \frac{1}{2}x + \frac{1}{2}[/tex]

A graph of the linear equation 3x - 4t = 12 has been plotted as shown in the image attached below.
What is a graph?In Mathematics, a graph can be defined as a type of chart that is typically used to graphically represent data points or ordered pairs on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis (x-coordinate) and y-axis (y-coordinate) respectively.
Next, we would use an online graphing calculator to plot the relationship between the value of x and the value of t as shown in the image attached below.
In conclusion, a graph which represents the linear equation (3x - 4t = 12) does not represent or show a proportional relationship between the value of x and t because they didn't pass through the origin (0, 0).

Question Help Ant Farming You have an ant farm with 21 ants. The population of ants in your farm will double every 3 months. The table shows the population growth of the ants over nine months. Decide whether the table represents a linear function or a nonlinear function. After one year, how many ants will there be in the ant farm? Population of Ants Number of 0 3 6 9 Months Population 21 42 84 168
After one year, 336 ants will there be in the ant farm. and the table represents a non-linear function. The solution is obtained using arithmetic operations.
What are arithmetic operations?
There are four basic operations which are listed as follows:
Addition(‘+’): This operation deals with finding the sum.Subtraction(‘-’): This operation deals with finding the difference. Multiplication(‘×’): This operation deals with finding the product.Division(‘÷’): This operation deals with finding the quotient.We are given that the population of ants in the farm will double every 3 months.
This means that in a year 4 times there will be increase in the population of ants because in a year there are 12 months and population of ants double every 3 months.
So, 12/3=4
Thus, in a year 4 times there will be increase in the population of ants.
Table representing population growth of the ants
Number of months Population of ants
0 21

Thus, after one year, 336 ants will there be in the ant farm.
It is a non linear function because there is not a constant increase in number. Every time the number of increase is different.
Hence, there will be 336 ants in the farm and it is a non linear function.

ow long to reach 733,500 baht with 9% interest?
pro samit
How long would it take to have 733,500 baht if your principal amount was 450,000 baht with a 9% interest rate?
If your principal amount is 450,000 baht and you earn a 9% interest rate, you would need to let the money accrue interest for a certain period of time in order to reach a balance of 733,500 baht.
To determine how long it would take to reach a balance of 733,500 baht, you can use the following formula:
Time (in years) = (733,500 baht - 450,000 baht) / (450,000 baht * 9%)
Plugging in the values, we get:
Time (in years) = (733,500 baht - 450,000 baht) / (450,000 baht * 0.09)
Time (in years) = (283,500 baht) / (40,500 baht)
Time (in years) = 7 years
So it would take approximately 7 years for your balance to reach 733,500 baht if your principal amount was 450,000 baht and you earned a 9% interest rate.

To find the original loan amount that Jane took out, you can use the following formula:
Original loan amount = (Interest paid / Interest rate) * (1 - 1/(1 + Interest rate)^(Number of years))
Plugging in the values, we get:
Original loan amount = (11,960 / 5.2%) * (1 - 1/(1 + 5.2%)^4)
Original loan amount = (11,960 / 0.052) * (1 - 1/(1.052)^4)
Original loan amount = $22,942.31
So the original loan amount that Jane took out was $22,942.31.

Find the unit rate 180 miles in 3hours
To find the unit rate, you need to divide the total number of miles by the number of hours it took to travel that distance.
In this case, the unit rate would be:

Unit rate = 60 miles/hour
So the unit rate is 60 miles per hour. This represents the number of miles traveled for every hour of travel.

Fred deposits $50 into an account. The account can be represented by the equation a(t)=50(1.25) where t is the time in years since opening the account. What is average rate of change in the value of the account for the first 4 years
The average rate of change is a measure of how the value of the account changes over time. To find the average rate of change for the first 4 years, you need to find the total change in the value of the account over that time period and divide it by the time period.
In this case, the value of the account at the end of the first 4 years is given by the equation:
a(4) = 50(1.25)^4
Plugging in the values, we get:
a(4) = 50(2.44140625)
a(4) = 122.07031250
The total change in the value of the account over the first 4 years is 122.07031250 - 50 = 72.07031250.
So the average rate of change in the value of the account over the first 4 years is:
Average rate of change = (72.07031250) / (4 years)
Average rate of change = $18.017578125/year

How to identify the equation of the linear functionThe slope, m of the linear function is calculated using the points on the graph (-3.1, -5.82) and (.6, -1.38)
m = (y₀ - y₁) / (x₀ - x₁)
m = (-1.38 - (-5.82)) / (6 - (-3))
m = (4.44) / (9)
m = 0.49
equation passing through point (.6, -1.38)
(y - y₁) = m' (x - x₁)
y - (-1.38) = 0.49 (x - 6)
y + 1.38 = 0.49x - 2.94
y = 0.49x - 2.94 - 1.38
y = 0.49x - 4.32
