B is right:
because it is -2 will make it 0 so it is two unit to the left.

The function g(x)= 112 Ln (0.121x) + 2011 models the year in which the population of New York City will equal x million people.

stellarik [79]

We are given function: $g(x)= 112\ ln (0.121x) + 2011$ .

Given function models a particular year of population of New York City.

x represents population of New York City ( In millions).

We need to estimate the population of New York City in 2020.

Because g(x) function represents a particular year of population of New York City and we are given year 2020, so we need to replace g(x) by 2020 and solve for x.

Replacing g(x) by 2020, we get

$2020= 112\ ln (0.121x) + 2011$ : <em>This is the required equation to estimate the population of New York City in 2020</em>

Let us solve the above equation for x now.

$2020=112\ln \left(0.121x\right)+2011$

$\mathrm{Switch\:sides}$

$112\ln \left(0.121x\right)+2011=2020$

$\mathrm{Subtract\:}2011\mathrm{\:from\:both\:sides}$

$112\ln \left(0.121x\right)+2011-2011=2020-2011$

$Simplify$

$112\ln \left(0.121x\right)=9$

$\mathrm{Divide\:both\:sides\:by\:}112$

$\frac{112\ln \left(0.121x\right)}{112}=\frac{9}{112}$

$\mathrm{Simplify}$

$\ln \left(0.121x\right)=\frac{9}{112}$

$\mathrm{Apply\:log\:rule}:\quad \:a=\log _b\left(b^a\right)$

$\frac{9}{112}=\ln \left(e^{\frac{9}{112}}\right)$

$\ln \left(0.121x\right)=\ln \left(e^{\frac{9}{112}}\right)$

$0.121x=e^{\frac{9}{112}}$

$\mathrm{Divide\:both\:sides\:by\:}0.121$

$\frac{0.121x}{0.121}=\frac{e^{\frac{9}{112}} }{0.121}$

$x=8.95598$ ≈ 9 million people.

So, we can say..

Population of New York City in 2020 would be 8.95598 millions or 9 million ( approximately).

Need help. Thank you

The answer is D.
The side lengths aren't the same and you can tell by calculating the hypotenuses of sides AB and sides BC.
For AB 2^2+5^2= 29 The length is root 29.
For BC 2^2+4^2=20 The length is root 20.
A square must have equal side lengths, which this figure does not
