Answer

A) 2 ln 2 - 2 ln 3

Explanation

Using the laws of logarithms:

ln (x/y) = ln (x) - ln (y)

ln (4/9) = ln (4) - ln (9)

This can be written as

ln (2^2) - ln (3^2)

Another law is:

ln (n^m) = m ln(n)

So finally:

2ln (2) - 2ln 3

What is the equation<br>

slava [35]

Answer:

B. $(x+1)^2+(y-2)^2=9$

Step-by-step explanation:

The given circle is centered at $(-1,2)$ and has radius 3 units.

The equation is given by

$(x-a)^2+(y-b)^2=r^2$

where (a,b) is the center and r is the radius.

We substitute the values to obtain;

$(x--1)^2+(y-2)^2=3^2$

$(x+1)^2+(y-2)^2=9$
