Exposure to ionizing radiation is known to increase the incidence of cancer. One thousand laboratory rats are exposed to identical doses of ionizing radiation, and the incidence of cancer is recorded during subsequent days. The researchers find that the total number of rats that have developed cancer t months after the initial exposure is modeled by for months. Find the rate of growth of the number of cancer cases at the 7th month.
Missing information :
The model was omitted from the question ; the possible model relating to the question was browsed online and could possibly be :
N(t) = 1.07t^2.3 for 0 ≤ t ≤ 10 months
Answer:
30.9 cases per month
Step-by-step explanation:
Given the model to determine the number of rats that have developed cancer after initial exposure ; N(t) = 1.07t^2.3
N(t) = 1.07t^2.3
Take the first derivative of N with respect to t to obtain the rate of change ;
N'(t) = (1.07)(2.3)t^2.3-1
N'(t) = (1.07)(2.3)t^1.3
The rate of growth of cancer cases at the 7th month can be calculated thus :
t = 7
N'(7) = (1.07)(2.3)t^1.3
N'(7) = 1.07 * 2.3 * 7^1.3
N'(7) = 1.07 * 2.3 * 12.549529
N'(7) = 30.884
The rate of growth of cancer at the 7th month is 30.9 cases per month.

Avocado Pickers are paid as shown below. What would be the gross
earnings for a worker that picks 1,108 avocados?
1 - 500 Avocados $0.10 each
501 - 700 Avocados $0.14 each
Over 700 Avocados $0.18 each
Answer:
The avocado picker earned $151.44.
Step-by-step explanation:
Given that avocado pickers are paid $ 0.10 if they collect from 1 to 500 avocados, $ 0.14 if they collect from 500 to 700 and $ 0.18 if they collect more than 700, to determine what would be the gross earnings for a worker that picks 1,108 avocados, the following calculation must be done:
1,108 - 700 = 408
700 - 500 = 200
500 x 0.10 + 200 x 0.14 + 408 x 0.18 = X
50 + 28 + 73.44 = X
151.44 = X
Therefore, the avocado picker earned $151.44.

Whats the value of 42÷(2+5)•3
Answer:
Step-by-step explanation:
42÷(2+5)•3 =
first we deal with the parentheses
42÷7•3
now we solve left to right
42÷7•3 = 6•3 = 18
The order of operations is:
Solve the parentheses first. Apply the same set of rules to whatever is inside the parentheses).
Solve multiplication and division - go from the left to right.
Solve addition and subtraction - go from left to right.
And you have the answer!
In this problem we only had division, multiplication and parentheses with addition inside.
Also, in the future you'll probably need to update the above rules with powers, roots and other things.

Find the volume of a cylinder that has a height of 8 inches and a diameter of 14 inches.
Answer:
[tex]V=1232\ inches^3[/tex]
Step-by-step explanation:
Given that,
The height of a cylinder, h = 8 inches
The diameter of the cylinder, d = 14 inches
Radius, r = 7 inches
We need to find the volume of the cylinder. The formula for the volume of a cylinder is given by :
[tex]V=\pi r^2 h\\\\=\dfrac{22}{7}\times 7^2\times 8\\\\V=1232\ inches^3[/tex]
So, the volume of the cylinder is equal to [tex]1232\ inches^3[/tex].

Line m passes through the point (1, 2) and has a slope of 2/5 What is the equation of line m in standard form?
Answer:
5y - 2x = 8
Step-by-step explanation:
First off we have to find the y-intercept with : b = y-mx
[tex]b=2-(\frac{2}{5})(1)[/tex]
[tex]b=\frac{10}{5}-\frac{2}{5}[/tex]
[tex]b=\frac{8}{5}[/tex]
now we have the point slope form
[tex]y=\frac{2}{5}x+\frac{8}{5}[/tex]
Multiply both sides by 5
[tex]5y=2x+8[/tex]
Subtract 2x from both sides
[tex]5y-2x=8[/tex]
