QUESTION 1
The given circle has equation:
We can rewrite to obtain;
This is equation is now in the form;
Where (h,k)=(0,0) is the center of the circle and 
is the radius.
QUESTION 2
The center of the circle is at (1,1) and passes through the point (4,5).
The radius of this circle is given by;
units.
We substitute into the formula;
Expand if you wish;
Answer:
a- she needss to buy 4 packs
b- he needs to buy 5 boxes
Step-by-step explanation:
15 = 0.25x
1500 = 25x
60 = x
The original price was $60.
Answer: 10 verticesTo make a full circle(360 °), the number of 40° lines you need will be: 360/40=9 lines. So, the base of the pyramid would be made of 9 lines.Pyramid has a base and sides. The sides number is equal to the number of lines of the base. Then, the number of faces/vertices would be: 1 + 9= 10
If the question saying literally 40 edges(not degrees), then the pyramid base would be 40 lines. In this case, the number of vertices would be: 1+40=41
