The population of a city grows exponentially at rate of 8% per year.Find the number of years it takes for the population to be d

Ilya [14]

Answer:

<em>It will take 9 years for the population to double</em>

Step-by-step explanation:

<u>Exponential Growth </u>

The natural growth of some magnitudes can be modeled by the equation:

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

Where P is the actual amount of the magnitude, Po is its initial amount, r is the growth rate and t is the time.

The population of a city grows at a rate of r=8% = 0.08 per year. We are required to find when (t) the population will double, or P=2Po.

Substituting in the equation:

$2P_o=P_o(1+0.08)^t$

Simplifying:

$2=(1.08)^t$

Taking logarithms:

$\log 2=\log (1.08)^t$

Applying the exponent property of logs:

$\log 2=t\log (1.08)$

Solving for t:

$\displaystyle t=\frac{\log 2}{\log (1.08)}$

Calculating:

$t\approx 9$

It will take 9 years for the population to double

Round 248,739 to the nearest hundred

vampirchik [111]

Look at your hundredth spot which is where the 7 is. So…

248, 739

Since 3 is not 5 or higher you cant round 7 up to 8. So your correct answer is 248,700

Hope this helps!

Which Choice is equivalent to the quotient shown here when x is greater or equal to 0

m_a_m_a [10]

$\sqrt{ \frac{27x}{48} } = \sqrt{ \frac{ {3}^{3}x}{ {2}^{4} \times 3 } } = \sqrt{ \frac{ {3}^{2}x }{ {2}^{4} } } = \frac{3 \sqrt{x} }{4}$

Paul [167]

Answer:

<h2>3.05x(output for x)</h2><h2>39.65</h2>

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>

function
PEMDAS

<h3>let's solve:</h3>

according to the question

the function is

f(x)=3.05x(first answer)

let's justify

f(1)=3.05×1

=3.05

LIKEWISE

f(3)=3.05×3

=9.15

therefore

it is the function

answer for the second question

f(13)=3.05×13

=39.65
