The formula for the equation of a circle is:
(x - h)^2 + (y - k)^2 = r^2
(h, k) is the center.
So the equation would be:
(x + 2)^2 + (y - 3)^2 = 5^2
or
(x + 2)^2 + (y - 3)^2 = 25

Answer:
The period of given function is 
So, Option B is correct.
Step-by-step explanation:
In this question we need to find the period of the function y= 3 sin x/8
The formula used to find period of function is: 
We need to know the value of b.
To find the value of b we compare the standard equation with the equation of function given.
Standard Equation: y = a sin(bx - c) +d
Given Equation: y= 3 sin(x/8)
Comparing we get:
a= 3
b= 1/8
c= 0
d=0
So, we get the value of b i.e 1/8. Putting it in the formula to find period of given function.


Solving,


So, the period of given function is 
Answer:
I think 1/4
Step-by-step explanation:
So, you first should find a common denominator so you can add the fractions together.
So, 1/4 + 1/3 + 1/6 becomes 3/12+4/12+2/12.
Add that up, you get 9/12.
Simplify.
9/12 = 3/4
3/4 is how much is dug out. 4/4 - 3/4 is 1/4. That's how much for digging is left, I believe.
