Answer:

$P(6) = 10(1.4)^{6} = 75.2$

Step-by-step explanation:

The number of people who receive the email after t weeks can be modeled by the following equation.

$P(t) = P(0)r^{t}$

In which P(0) is the initial number of poeple who received the email and r is the factor.

Karim sent a chain email to 10 of his friends.

This means that $P(0) = 10$

The number of people who got the email increases by a factor of 1.4 every week.

This means that $r = 1.4$

So

$P(t) = 10(1.4)^{t}$

Which expression gives the number of people who got the email after 6 weeks?

$P(6) = 10(1.4)^{6} = 75.2$

$\bf ~~~~~~~~~~~~\textit{negative exponents} \\\\ a^{-n} \implies \cfrac{1}{a^n} \qquad \qquad \cfrac{1}{a^n}\implies a^{-n} \qquad \qquad a^n\implies \cfrac{1}{a^{-n}} \\\\ -------------------------------\\\\ 8^{-2}\cdot \cfrac{3^0-8^{-3}}{4^{-5}}\implies 8^{-2}\cdot \cfrac{1-\frac{1}{8^3}}{\frac{1}{4^5}}\implies 8^{-2}\cdot \cfrac{1-\frac{1}{(2^3)^3}}{\frac{1}{(2^2)^5}}$

$\bf 8^{-2}\cdot \cfrac{\quad \frac{512-1}{2^9}\quad }{\frac{1}{2^{10}}}\implies (2^3)^{-2}\cdot \cfrac{\quad \frac{511}{2^9}\quad }{\frac{1}{2^{10}}}\implies 2^{-6}\cdot \cfrac{511}{2^9}\cdot \cfrac{2^{10}}{1} \\\\\\ 2^{-6}\cdot \cfrac{511\cdot 2^{10}}{2^9}\implies 2^{-6}\cdot 511\cdot 2^{10}\cdot 2^{-9}\implies 2^{-6}\cdot 511\cdot 2^{10-9} \\\\\\ 2^{-6}\cdot 511\cdot 2\implies 511\cdot 2^{-6}\cdot 2\implies 511\cdot 2^{-6+1}\implies 511\cdot 2^{-5} \\\\\\ 511\cdot \cfrac{1}{2^5}\implies \cfrac{511}{32}$

Write an expression in simplest form that represents the total amount in each situation.

vampirchik [111]

Answer:

T = 18x + 25

Step-by-step explanation:

Let T = total amount in $

x amount of tents at $10 each (10x)

same amount of tables for $8 each (+8x)

one clown for $25 (+25)

so T = 10x + 8x + 25

T = 18x + 25
