Answer: The answer is given below.
Step-by-step explanation: The given circles are:
Circle 1: centre (2, 3) and radius 4
Circle 2: centre (2, 3) and radius 12.
The equations of circle 1 and circle 2 are respectively given as :
These two circles are drawn on the graph as shown in the attached figure.
We can easily see that the Circle 2 is a dilation of Circle 1 with a scale factor
Thus, the two circles are similar.
I believe the answer is $17.50, she earned $30 off of $600 meaning she had a 5% interest rate and 5% of 350 is $17.50

Answer:
4
Step-by-step explanation:
There is a rule for logarithms that says:
.
This is actually called quotient rule and it's name is based off the right hand side of the equation there.
So you have that you can write your right hand side as:
.
So your equation is:
Now let's write this in the equivalent exponential notation:
So the value of the given fraction is .
Note! In general, the equivalent exponential form of is .
The answer is : t= 4 , -3
