Q. Rewrite in simplest terms:

9(-0.6 r+0.8)+7(0.3 r-0.6)

\newline

Answer:

Distribute Terms: Distribute the $9$ and $7$ into their respective parentheses. $\newline$ We need to multiply each term inside the parentheses by the number outside the parentheses. $\newline$ For the first set: $9 \times (-0.6 r) = -5.4 r$ and $9 \times 0.8 = 7.2$ $\newline$ For the second set: $7 \times (0.3 r) = 2.1 r$ and $7 \times (-0.6) = -4.2$
Combine Like Terms: Combine like terms. $\newline$ Now we add the results of the distribution together, combining the $r$ terms and the constant terms. $\newline$ $-5.4 r + 2.1 r = -3.3 r$ $\newline$ $7.2 - 4.2 = 3$
Write Final Expression: Write the final simplified expression. $\newline$ Combine the results from Step $2$ to get the final simplified expression. $\newline$ $-3.3 r + 3$

Consider the following problem:

\newline

The population of ants in Chloe's ant farm changes at a rate of

r(t)=-15.8 \cdot 0.9^{t}

ants per month (where

t

is time in months). At time

t=0

, the ant farm's population is

150

ants. How many ants are in the farm at

t=4

\newline

Which expression can we use to solve the problem?

\newline

\int_{0}^{4} r(t) d t

\newline

\int_{3}^{4} r(t) d t

\newline

150+\int_{3}^{4} r(t) d t
