Answer:
I NEED MORE CONTEXT
Step-by-step explanation:
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.
So what you are looking for is the hypotenuse of the triangle DCF.
We know DC is 3cm, so we need CF.
BC and CF and CF create a right triangle.
Using Pythagorean Theorem, CF is about 10.2
Now using Pythagorean Theorem again, 3^2 +10.2^2=113
The sqaureroot of that is 10.6. So 10.6 is your answer
Answer:
-6

Answer:
x = 30
Step-by-step explanation:
x + 2x + 3x = 180
<u>6x</u> = <u>180</u>
6 6
x = 30
