Answer:

180 pages

Step-by-step explanation:

First you find the slope of the line assuming this is linear. it's just the Rise over Run. so go up 4 over 2 which means the slope is going up two. so do 90 times 2 which is 180. That means Jeff read 180 pages.

A culture started with 4000 bacteria after 8 hours it grew to 4400 bacteria. Predict how many bacteria will be present after 9 h
Leno4ka [110]
\bf \qquad \textit{Amount for Exponential change}\\\\&#10;A=P(1\pm r)^t\qquad &#10;\begin{cases}&#10;A=\textit{accumulated amount}\\&#10;P=\textit{starting amount}\\&#10;r=rate\to r\%\to \frac{r}{100}\\&#10;t=\textit{elapsed period}\\&#10;\end{cases}\\\\&#10;-------------------------------\\\\

\bf A=P(1+r)^t\qquad &#10;\begin{cases}&#10;\textit{hour 0, starting point}\\&#10;t=0\qquad A=4000&#10;\end{cases}\implies 182=ae^{k0}&#10;\\\\\\&#10;4000=P(1+r)^0\implies 4000=P&#10;\\\\\\&#10;thus\qquad A=4000(1+r)^t\\\\&#10;-------------------------------\\\\

\bf A=P(1+r)^t\qquad &#10;\begin{cases}&#10;\textit{8 hours later}\\&#10;t=8\qquad A=4400&#10;\end{cases}\implies 4400=4000(1+r)^8&#10;\\\\\\&#10;\cfrac{4400}{4000}=(1+r)^8\implies \cfrac{11}{10}=(1+r)^8\implies \sqrt[8]{\cfrac{11}{10}}=1+r&#10;\\\\\\&#10;\sqrt[8]{\cfrac{11}{10}}-1=r\implies 0.012\approx r\qquad thus\qquad \boxed{A=4000(1+0.012)^t}

how many bacteria after 9 hours? well, 9hours later is just t = 9, plug that in, to get A
