Someone give me the answer

a function that model the number of people that receives email in week t  is .

Step-by-step explanation:

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

, In question initial value is 37 & and for every 9.1 weeks there is increase in people by a factor of 4 i.e.

⇒

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

⇒

Therefore , a function that model the number of people that receives email in week t  is .

if you use photomath right away it will give you the answer not like this app that you have to wait for people.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
