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 :
If a graph of a system of two equations shows two lines that coincide on a coordinate plan there would be C.)Infinitely many solutions
I hope this helps, have a great day.
Answer:
13.75 is your answer
Step-by-step explanation:
find area of whole triangle 5.5*7*1/2=19.25
Find area of blank spot 5.5*2*1/2=5.5
Subtract 19.25-5.5=13.75
One important feature of the parabola is that it has an extreme point, called the vertex. If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function.
