Vikki [24]

Answer:

x = - 3, x = - 6

Step-by-step explanation:

${x}^{2} + 9x + 18 = 0 \\ \\ {x}^{2} + 6x + 3x + 18 = 0 \\ \\ x(x + 6) + 3(x + 6) = 0 \\ \\ (x + 6)(x + 3) = 0 \\\\ x + 3 = 0 \: \: or \: \: x + 6 = 0 \\ \\ x = - 3, \: \: or \: \: x = - 6 \\ \\$

The number of bacteria present in a culture after t minutes is given as b=1000e^kt where k is a constant. If there are 8520 bact

Kryger [21]

To solve this problem, plug 8250 in for b and 15 in for t and then solve for k:

$8250=1000e^{15k}$

*Divide both sides by 1000*

$8.25=e^{15k}$

*Take the natural log (ln) of both sides*

2.1102=15k

*Divide both sides by 15*

0.1406=k

0.1406 rounds to 0.141 which is close to a. 0.143.

Hope this helps!!
