(x - xc)² + (y - yc)² = r²

Where xc and yc are center coordinates

(x - (-4))² + (y - 3)² = 2²

(x + 4)^2 + (y - 3)^2 = 4

x² + 2.x.4 + 4² + y² - 2.y.3 + 3² = 4

x² + 8x + 16 + y² - 6y + 9 = 4

x² + y² + 8x - 6y + 25 - 4 = 0

x² + y² + 8x - 6y + 21 = 0

Softa [21]

Step-by-step explanation:

f(x) = -4x^2+24x-29

= -4(x^2-6x)-29

= -4(x-3)^2 -4(-9) -29

= -4(x-3)^2 +36-29

= -4(x-3)^2 +7

maximum height = 7m

The ratio of angle measures is 1:2:2. Classify the triangle by its angle measures. a.acute triangle b.right triangle c. obtuse t
HACTEHA [7]
Angles in a triangle must add up to 180°, so you could use this information to find the values of the angles. 1 + 2 + 2 = 5, 180 ÷ 5 = 36. 36 × 2 = 72, so 36 + 72 + 72 = 180. This means that the answer is A. acute, because all of the angles are below 90°. I hope this helps!
