Answer:

Step-by-step explanation:
We can write this rate as an ordinary differential equation.

Where a is proportional constant, P the population variable, and t the time.

Integrating each side of the equation.



To find C we need to use the initial condiction, it means evaluae P at t=0.


Now, we use the sentence the population has doubled in 5 years.

We can find "a" in this condition.




Finally, let's find how long will it take to triple.




I hope it helps you!
Answer:
The fourth choice.
Step-by-step explanation:
Because since 90 miles is basically counted as your first day, you do the number of days, n, minus 1 and then multiply it by 5 to find the number of miles walked after the first day. Then you add it to 90.
Answer:
The answer is 10.5 or 10 1/2
Step-by-step explanation:
1) A=LxW
2) the height is given but you do not have the width So Divide.
3) first turn the fraction into decimals
H= 12 1/4= 12.25
A= 128 5/8= 128.625
4) 128.625 divided by 12.25 Give you 10.5
5) you can change 10.5 into a fraction 10 1/2
hopes this helps.
Answer:
340/4
Step-by-step explanation:
i beleive the answer would be 340 = 4 but if 340/4 is an option you could choose it.
<h3>Answer: Choice A) x+14</h3>
=======================================
Work Shown:
(f-g)(x) = f(x) - g(x)
(f-g)(x) = (f(x)) - (g(x))
(f-g)(x) = (3x+10) - (2x-4)
(f-g)(x) = 3x+10 - 2x+4
(f-g)(x) = (3x-2x) + (10+4)
(f-g)(x) = x+14
