Answer:
20.922
Step-by-step explanation:
Evaluate ln 7.2 on a calculator; the correct result is 1.974.
Multiply that by 3, obtaining 5.922.
Finally, add 15 to that result:  y = 15 + 3 In 7.2 = 20.922

Well, the number should be 2,222 since she wants the hundreds place to be a 2, being worth 200. Since she wanted all the digits to have the same number, it would be 2,222 for your final answer.
Hope this helped!

Equation of a circle is (x-x1)+(y-y1)=r²
when x1 and y1 are the coordinates of the centre
So you can substitute the centre in to get (x-5)²+(y+9)²=r²
When you draw a diagram it's obvious the radius is 9
9²=81
Therefore equation is (x-5)²+(y+9)²=81
Any questions, just ask :)
