The solution for the problem is:
I will first get the first five terms so that I could easily locate the third term of this problem:So, substituting the values:
T(1) = 1^2 = 1T(2) = 2^2 = 4T(3) = 3^2 = 9T(4) = 4^2 = 16T(5) = 5^2 =25
So the third terms is T(3) = 3^2 = 9

Martha wants to build a rectangular wooden border around the perimeter of her children's playground. She can find the perimeter
lutik1710 [3]

Answer: The perimeter of Martha's wooden border = 44 feet.

Step-by-step explanation:

Given: The formula to find the perimeter = 2w + 2l. , where w = width and l = length

If l= 12 feet and w = 10 feet

Then, the perimeter of Martha's wooden border = 2(10)+2 (12) feet

The perimeter of Martha's wooden border = 20+24 feet

The perimeter of Martha's wooden border = 44 feet

Therefore, the perimeter of Martha's wooden border = 44 feet.

Use the graph representing bacteria decay to estimate the domain of the function and solve for the average rate of change across
nasty-shy [4]

Answer:

Domain is [0,18]

Average rate of change of bacteria per minute is -3333.33.

Step-by-step explanation:

Domain is the possible values of x.

From the graph, it's clear that the x values ranges from 0 to 18 as the end points of the graph are (0,60) and (18,0)

So, domain of the function is [0,18].

Now, average rate of change is negative as there is bacteria decay.

Average rate of change is given as the negative ratio of y intercept to the x intercept.

Here, x-intercept is 18 and y-intercept is 60000.

So, average rate of change is given as,

R_{avg}=-\frac{60000}{18}=-3333.33

Therefore, average rate of change of bacteria per minute is -3333.33.
