Tobias sent a chain letter to his friends, asking them to forward the letter to more friends. The number of people who receive t

dybincka [34]

Answer:

$P(t)=37\cdot 4^{t/9.1}$

Explanation:

This is an exponential growing: there is a constant growing factor which multiplies the value number of letters sent every week.

The growing factor 4 letters every 9.1 weeks means that every 9.1 weeks the number of letters is multiplied by 4.

Then, if the number of weeks is t, the number of times the number of letters increase is t/9.1.

Then, the exponential function that models the number of people who receive the email t weeks since Tobias initially sent the chain letter, has the form:

$P(t)=Initial\text{ }value\cdot 4^{(t/9.1)}$

Tobias initially sent the chain letter to 37 friends; thus, the initial value is 37, and the complete function is:

$P(t)=37\cdot 4^{t/9.1}$ , where t is the number of weeks since Tobias initially sent the chain letter.

In three bowling games,David scored 139,143, and 144. What score will David need in the fourth game in order to have an average

Liono4ka [1.6K]

Let's find out.

David needs to score an average of 145 across all four games, so first we do:

145 × 4 = 580

Then we add all the scores he currently has:

139 + 143 + 144 = 426

Then we subtract 426 from 580 to find out how much he needs to score for his fourth:

580 - 426 = 154

David needs to score 154 on his 4th game to have an average score of 145 for all 4 games.
