A culture started with 2000 bacteria. After 4 hours, it grew to 2,200 bacteria. Predict how many bacteria will represent after 9

S_A_V [24]

Y=2000* $e^{k*t}$

2200=2000* $e^{k*4}$

$e^{k}= ( \frac{22}{20} )^{(1/4)}$ 

so,
y at t=8 is 2000*( $( \frac{22}{20} )^{(1/4)}$ )^8
y = 2000(22/20)^2=2000*1.21=2420 thats the answer i hope.

SOMEONE HELP ME PLS, I'M stuck on this one since yesterday!

$\bf \begin{cases}
F = \{(0, 1), (\stackrel{x}{2}, \stackrel{y}{4}), (4, 6), (6, 8)\} & F(\stackrel{x}{2})=\stackrel{y}{4}
\\\\\\
G = \{(\stackrel{x}{2}, \stackrel{y}{5}), (4, 7), (5, 8), (6, 9), (7, 5)\} \qquad & G(\stackrel{x}{2})=\stackrel{y}{5}
\end{cases} 
\\\\\\
(F\cdot G)(2)\implies F(2)\cdot G(2)\implies 4\cdot 5\implies 20$
