Answer:
(a) center: (0, 0); radius: 4
(b) center: (8, -3); radius: 10
(c) center: (-2, -7); radius: 7
(d) center: (6, 0); radius: 1
(e) center: (0, 0); radius: 5
(f) center: (3, 8); radius: 8
Step-by-step explanation:
In the figure attached, the complete question is shown.
Equation of a circle with center (h, k) and radius r:
(x - h)² + (y - k)² = r²
I basically pick a couple random numbers for both variables and plug them in to see if they are true.
Answer:
x = 3 and y = 2
x = 1.25 and y = 1.75
Step-by-step explanation:
Part 1:
See the diagram first.
If the two arrow lines are parallel then, the two triangles are similar.
So, the corresponding sides of the triangles are proportional.
So,
Hence, x = 3 and y = 2 (Answer)
Part 2:
See the diagram first.
If the two arrow lines are parallel then, the two triangles are similar.
So, the corresponding sides of the triangles are proportional.
So,
⇒
⇒ x = 1.25
Again,
⇒ y = 1.75
Hence, x = 1.25 and y = 1.75 (Answer)
