Answer: a. Radius of circle = 
b. The equation of this circle : 
Step-by-step explanation:
Given : Center of the circle = (3,10)
Circle is passing through (12,12).
a. To find the radius we apply distance formula (∵ Radius is the distance from center to any point ion the circle.)
Radius of circle = 
Radius of circle = 
i.e. Radius of circle =
b. Equation of a circle = 
, where (h,k)=Center and r=radius of the circle.
Put the values of (h,k)= (3,10) and r= , we get
∴ The equation of this circle :
Concentric circles because if a line is tangent to one circle, it would only intersect teh other
Answer:
Yes
Step-by-step explanation:
To be a function, the graph must pass the vertical line test.
The vertical line test is simple. Imagine you draw an infinite number of vertical lines. In all of these lines, it should never hit the function twice in the same x value.
For example, if it hits (4, 2) and (4, 7), the graph is not a function because there are two points with the same x value.
The formula is
I=prt
I amount earned?
P 2500
R interest rate 0.085
T time 4years
I=2,500×0.085×4
I=850
A/b times b/c is = ab/bc
which can be written as a/c times b/b
anything over itself is 1 so b/b is one
a/b times b/c = a/c
