Does this table show a proportional relationship? If so, what is the constant of proportionality?
seropon [69]

Answer:

The answer is A: Yes 1/4 is the constant property.

This is because the x ration to y is 3 to 12. So we divide 12 by 3 to get our answer which is 4. That is equivalent to 1/4 since we divided.

I hope this helps and if it did pls give me brainliest!

Find the missing side length of the right triangle.
Tomtit [17]
This is just some pythagorean theorem, or a^2 + b^2 = c^2. We have a and b, which is 9 and 12, and we need to find c. To find c, we need to first square those, giving u 81 and 144. Now, we need to add them, giving us 225, meaning c^2 = 225. However, we need to find c on its own, so we have to find the square root of 225. That would be 15.

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!
storchak [24]

Answer:

a_n = 1200(1.35)^n

Step-by-step explanation:

Equation to remember:

P_0(1+r)^t where t = time

P_0 = 1200 since that's the initial population

r  = .35 rate of change \\

t  = 5 years

Plug in the numbers;


a_5 = 1200(1+.35)^5


Since the prompt looks like it's asking for an equation given any number of years.. then just change 5 to n for number of years.


a_n = 1200(1.35)^n
