number of bacteria in a certain population Increases according to a continuous exponential growth model with How many hours does

vladimir1956 [14]

Answer:

It takes 1.77 hours for the population to double.

Step-by-step explanation:

Equation for population growth:

The equation for population growth, after t hours, with a growth rate parameter of r, as a decimal, is given by:

$P(t) = P(0)(1+r)^t$

Growth rato parameter of 48% per hour

This means that $r = 0.48$ . So

$P(t) = P(0)(1+r)^t$

$P(t) = P(0)(1+0.48)^t$

$P(t) = P(0)(1.48)^t$

How many hours does it take the size of the sample to double?

This is t for which P(t) = 2P(0). So

$P(t) = P(0)(1.48)^t$

$2P(0) = P(0)(1.48)^t$

$(1.48)^t = 2$

$\log{(1.48)^t} = \log{2}$

$t\log{1.48} = \log{2}$

$t = \frac{\log{2}}{\log{1.48}}$

$t = 1.77$

It takes 1.77 hours for the population to double.

Answer:

$\sf \boxed{\sf \frac{3}{2} } \ miles \ per \ day$

Explanation:

$\sf unit \ rate: \dfrac{Total \ distance \ (miles)}{Total \ time \ taken \ (day)}$

Here given:

$Total \ Distance : 8\dfrac{1}{4} \ or \ 8.25$

$Total \ Time \ taken : 5\dfrac{1}{2} \ or \ 5.5$

Find unit rate:

$\rightarrow \sf unit \ rate: \dfrac{8.25 }{5.5 }$

$\rightarrow \sf unit \ rate: 1.5 \ miles \ per \ day$
