Answer:
Explanation:
The number of emails is multiplied by <em>4</em> every <em>9.1 weeks.</em>
Thus, since <em>Tobias initially sent the chain letter to 37 friends</em>, the number of letters will grow as per this geometric series:
Start: 37 letters
- In 2 × 9.1 weeks: 37 × (4)²
- In 3 × 9.1 weeks: 37 × (4)³
As you see, the exponent is the number of weeks divided by 9.1
Thus, if your variable is the number of weeks, t, then the exponent is t/9.1
And the exponential function, P(t) will be:
![P(t)=37\times (4)^{(t/9.1)}](https://tex.z-dn.net/?f=P%28t%29%3D37%5Ctimes%20%284%29%5E%7B%28t%2F9.1%29%7D)
Answer:
-9
Step-by-step explanation:
The slope of the the solving equation is triple the slope of the given equation. Therefore, the y coefficient must also be triple of the other y coefficient.
Answer:
0.10 for 1/4 of a mile so 8 would be 32 times more. Which would be .1 x 32 or $3.20

Step-by-step explanation:
Let
be the amount of food needed for one man for one day. At the beginning, we have enough food for 400 men for 40 days, i.e.
![400\cdot 40\cdot x = 16000x](https://tex.z-dn.net/?f=400%5Ccdot%2040%5Ccdot%20x%20%3D%2016000x)
After 10 days, the 400 men will have consumed
![400\cdot 10\cdot x = 4000x](https://tex.z-dn.net/?f=400%5Ccdot%2010%5Ccdot%20x%20%3D%204000x)
food, impliying that the food remaining is
![16000x-4000x=12000x](https://tex.z-dn.net/?f=16000x-4000x%3D12000x)
If 200 more men join the garrison, there are now 600 men. Each of them requires
food each day, and there are
units of food remaining. They will last
days.
