\(x^2+y^2-18x-14y+120=0\)

Converting to standard circle equation:

\(\left(x−a\right)^2+\left(y−b\right)^2=r^2\)

\(\left(x-9\right)^2+\left(y-7\right)^2=\left(\sqrt{10}\right)^2\)

\(center: (9, 7)\)

\(radius: \sqrt{10}\)

Hello Guest!!!

f(17) = We use the second function: 17-13=4

f(4)= We use the first function (4^2)-4=12

f(12) = We use the first func again: (12^2)-4 =140

We have 6 numbers in the set "2, 2, 5, 6, 8, and 9", so we have 6! to find the different positive 6 digit integers that can be formed.

And we have two 2s... which means that we need to divide by 2!

That will give us: 6!/2! which is 360 different positive 6 digit numbers

We see that since BDC is an isosceles triangle, so, therefore, angle BDC = angle BCD = x.

38 + 2x = 180

2x = 142

x = 71

From here, we see that angle EDB = 180 - 71 = 109

We know that 143+44 = 187

We also know that 142+45 = 187

I think you got the idea by now:

We eventually work all the way in giving us 187*50

==== 9350

It's fine

Im sure its New York 

I would say it is New York:

This is because the present and past human impact measurements have a bigger change than that of Amazon rainforest:

New York: 893-625 = 268ppm

Amazon Forest: 403-318 = 85ppm

I would go with NY

But something seems wrong with the info you sent me because it does not show the future impacts which is what is needed to solve but...

Its Newyork

The area of a trapezoid is (base1+base2*height)/2

The two bases are 8 and 5

The height is 4

SO substituting these known values into our formula gives us:  ((8+5)(4))/2

((8+5)(4))/2 = 26

So the area of the trapezoid is 26 meters.

"When recommending solutions to decrease human impact, which location were you able to make the greatest positive impact? Please explain your selection by using data from the simulation."

I am assuming this is probably Earth/Env Science...

Can you show a picture of the simulation so I can get a better understanding?

\(\frac{\left(-2x-12\right)}{2}>7\left(3-4x\right)\)

\(\mathrm{Multiply\:both\:sides\:by\:}2\)

\(\frac{-2x-12}{2}\cdot \:2>7\left(3-4x\right)\cdot \:2\)

\(-2x-12>14\left(3-4x\right)\)

\(-2x-12>42-56x\)

\(\mathrm{Add\:}12\mathrm{\:to\:both\:sides}\)

\(-2x-12+12>42-56x+12\)

\(Simplify\)

\(-2x>-56x+54\)

\(\mathrm{Add\:}56x\mathrm{\:to\:both\:sides}\)

\(-2x+56x>-56x+54+56x\)

\(Simplify \)

\(54x>54\)

\(\mathrm{Divide\:both\:sides\:by\:}54\)

\(\frac{54x}{54}>\frac{54}{54}\)

\(Simplify\)

\(x>1\)
