Question

1) The center of a circle is at (-10,6) and it has a radius of 4. What is the equation of the circle?

2)(look at 1st attached pic)
0.6
1.4
1.2
0.7

3) (look at second attached pic)

4(look at last attached pic)

Answer 1

1. (x - h)² + (y - k)² = r²
(x - (-10)) + (y - 6)² = 4²
(x + 10)² + (y - 6)² = 16
The equation of the circle is (x + 10)² + (y - 6)² = 16.

2. The answer is A.

3. The equation of the parabola is y = ⁻⁵/₃₆x² - 1²/₃x - 2.

4. I don't know the answer to the problem.
