Someone give me the answer
Butoxors [25]

a function that model the number of people that receives email in week t  is P(t)=37(4)^{\frac{t}{9.1}} .

<u>Step-by-step explanation:</u>

Here we have , Tobias sent a chain letter to his friends . The number of people who receives the email increases by a factor of 4 in every 9.1 weeks , and can be modeled by a function P, which depends on the amount of time t weeks . Tobias initially sent letter to 37 friends . We need to write a function that model the number of people that receives email in week t . Let's find out:

Basically it's an exponential function as

f(x) = e^{ax} , In question initial value is 37 & and for every 9.1 weeks there is increase in people by a factor of 4 i.e.

⇒ P(t)=37(4)^t

But , wait ! People increase in every 9.1 weeks not every week so modified equation will be :

⇒ P(t)=37(4)^{\frac{t}{9.1}}

Therefore , a function that model the number of people that receives email in week t  is P(t)=37(4)^{\frac{t}{9.1}} .

2 (5y-4)&gt;32<br> Solve the inequality for y.
scoray [572]

Answer:

y > 4

Step-by-step explanation:

2 (5y-4)>32

Divide each side by 2

2/2 (5y-4)>32/2

5y-4 > 16

Add 4 to each side

5y-4+4 > 16+4

5y > 20

Divide each side by 5

5y/5 > 20/5

y > 4
