First, look at the x axis (this is the one labeled Minutes Used per month)
Find the number 40, then look at where the lines meet on that line. The red line for Plan B it’s at 8 dollars. The blue line for Plan A is at 4 dollars.
Plan B costs more.
To find the difference, subtract 4 from 8.
$8 - $4 = $4
Plan B costs 4 dollars more than Plan A.
If you have any further questions feel free to ask.
Hope this helps.

Hello!</h2>
The answer is:
In 2036 there will be a population of 32309 rabbits.

Why?</h2>
We can calculate the exponential decay using the following function:
![P(t)=StartAmount*(1-\frac{percent}{100})^{t}](https://tex.z-dn.net/?f=P%28t%29%3DStartAmount%2A%281-%5Cfrac%7Bpercent%7D%7B100%7D%29%5E%7Bt%7D)
Where,
Start Amount, is the starting value or amount.
Percent, is the decay rate.
t, is the time elapsed.
We are given:
![StartAmount=144,000\\x=7.2(percent)\\t=2036-2016=20years](https://tex.z-dn.net/?f=StartAmount%3D144%2C000%5C%5Cx%3D7.2%28percent%29%5C%5Ct%3D2036-2016%3D20years)
Now, substituting it into the equation, we have:
![P(t)=StartAmount(1-\frac{percent}{100})^{t}](https://tex.z-dn.net/?f=P%28t%29%3DStartAmount%281-%5Cfrac%7Bpercent%7D%7B100%7D%29%5E%7Bt%7D)
![P(t)=144000*(1-\frac{7.2}{100})^{20}](https://tex.z-dn.net/?f=P%28t%29%3D144000%2A%281-%5Cfrac%7B7.2%7D%7B100%7D%29%5E%7B20%7D)
![P(t)=144000*(1-0.072)^{20}](https://tex.z-dn.net/?f=P%28t%29%3D144000%2A%281-0.072%29%5E%7B20%7D)
![P(t)=144000*(0.928)^{20}](https://tex.z-dn.net/?f=P%28t%29%3D144000%2A%280.928%29%5E%7B20%7D)
![P(t)=144000*(0.928)^{20}](https://tex.z-dn.net/?f=P%28t%29%3D144000%2A%280.928%29%5E%7B20%7D)
![P(t)=144000*0.861=32308.888=32309](https://tex.z-dn.net/?f=P%28t%29%3D144000%2A0.861%3D32308.888%3D32309)
Hence, we have that in 2036 the population of rabbis will be 32309 rabbits.
Have a nice day!
Answer:
![x = 8](https://tex.z-dn.net/?f=x%20%3D%208)
Step-by-step explanation:
![21-x=13 \\ x = 21 - 13 \\ x = 8](https://tex.z-dn.net/?f=21-x%3D13%20%5C%5C%20x%20%3D%2021%20-%2013%20%5C%5C%20x%20%3D%208)
Answer:
336 ways
Step-by-step explanation:
The digits are 1, 2, 2, 4, 5, 5, 6, and 2 that is total eight digits.
The number 654-5222 contains 7 digits.
So, we have find The number of permutations for choosing 7 digits from 8 digits given above.
This can be done in following ways
= ![\frac{40320}{6\times2}](https://tex.z-dn.net/?f=%5Cfrac%7B40320%7D%7B6%5Ctimes2%7D)
= 336 ways
