(PLZ NEED HELP) The doubling time of a bacterial population is 10 minutes. After 80 minutes, the bacterial population was 80000.

kykrilka [37]

Answer:

Initial population = 313

Population after 5 hours = $3.36 \times 10^{11}$

Step-by-step explanation:

Let initial population = $x$

It is given that population gets doubled every 10 minutes.

Population after 10 minutes = $2x$

Population after 20 minutes = $2^{2} x$

Population after 80 minutes = $2^{8} x$ and it is given as 80000.

$\Rightarrow 2^{8} x = 80000\\\Rightarrow x = \dfrac{80000}{256}\\\Rightarrow x = 313$

So, initial population is 312.5 = ~313

To find, population after 5 hours i.e. 5 $\times$ 60 = 300 minutes

Population after 300 minutes =

$2^{30} x\\\Rightarrow 2^{30} \times 313\\\Rightarrow 3.36 \times 10^{11}$

So, the <em>answers </em>are:

Initial population = 313

Population after 5 hours = $3.36 \times 10^{11}$

Simplify the expression.<br><br> (6g)^3

Marina CMI [18]

Well, the exponent is distributed to the 6 and g.

g cannot be changed and therefore remains as $g^3$

$6^3$ can be simplified even further and into the number 216

Therefore, your answer should be:

$216g^3$

Please explain the steps to me . i’m genuinely confused

uranmaximum [27]

Answer:See below

Step-by-step explanation:

These angles are equal. All that needs to be done is setting the equations as equal and solving for the variables. Once the variables are found, input them back into the equation to find the angles. Once the variables are put into both equations, the result should be equal.
