Answer:
The correct answer is B = 15.9
Step-by-step explanation:
h = 27 cos 54 = 15.9
A B E
They all equal x = 3 once solved.
C = 6 and D = 9 so those are not correct.
Answer:
Center: (-7, -4)
radius = 4
Explanation:
- Equation: (x + 7)² + (y + 4)² = 16
Circle formula:
(h, k) denotes the center of the circle, "r is radius"
Rewrite the following equation in standard form:
- (x - (-7))² + (y - (-4))² = 4²
From this identify:
- h = -7, k = -4, radius = 4
This indicates an increase of 50%; or as a decimal .75.
