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:

1908
Step-by-step explanation:2% of 1800 is 36 36 x 3 is 108 + 1800 =1908
42.50$ ? 21 times 1.25 plus 13 times 1.25 = 42.50?
Answer:
D
Step-by-step explanation: since it is a open dot to the right it’s x>-3 open dot means less than or greater than going to right means greater than
(3x-2)(x+1)
3x*x+3x-2x-2
3x^2+3x-2x-2
3x*2+x-2
I think this is the answer
