Answer:

Step-by-step explanation:

your trying to make it equal, in order to do that you must do to the top what you did the bottom

20=100

to get from 20 to 100 you multiply by 5 so we multiply the top by 5 to make it equal

11/20x5/5=55/100

The population of Collin County, which follows the exponential growth model,

Anestetic [448]

Answer:

(a) k=0.06217

(b) $P=264036e^{0.06217t}$

Step-by-step explanation:

Population increased from 264,036 in 1990 to 491,675 in 2000.

Let assume , year 1990 as t=0

When t=0, population P = 264,036

When t=10, population P = 491,675

Exponential growth equation is P=P_0e^(kt)

$P_0$ is the initial population when t=0

So $P_0= 264,036$

When t=10, population P = 491,675

Plug in all the values and find out k

$491675 = 264036 e^{k*10}$

Divide both sides by 264036

$\frac{491675}{264036}=e^{k*10}$

To remove 'e' we take ln on both sides

$ln(\frac{491675}{264036})=lne^{10k}$

$ln(\frac{491675}{264036})=10kln(e)$

The value of ln(e) = 1

$ln(\frac{491675}{264036})=10k$

Divide both sides by 10

k=0.06217

Exponential growth equation is $P=P_0e^{kt}$

We know $P_0= 264,036$

Replace the value of k

$P=264036e^{0.06217t}$

Now , we find the population in 2012

For year 2012 , t= 12

So we plug on 12 for t and solve for P

$P=264036e^{0.06217*12}$

P = 556755.09504

556,755 is the population in 2012

Find the value of log(4) ∙ log(25) to five decimal places.

Fittoniya [83]

Answer:0.84164

Step-by-step explanation:

Given

$\log \left ( 4\right )\cdot \log \left ( 25\right )$

we know

$\log a^b=b\log a$

Applying this identity we get

$\log \left ( 2\right )^2\cdot \log \left ( 5\right )^2$

$=2\log \left ( 2\right )\times 2\log \left ( 5\right )$

$=4\times \log \left ( 2\right )\cdot \left ( 5\right )$

$=4\times 0.301029\times 0.698970$

$=0.84164$
