Answer:
see in the graph, the circle has: the centre I(3; -2)
r = 3
=> the equation: (x - 3)² + (y + 2)² = 9
Answer:

Step-by-step explanation:
The reason is because you don't know the Inital amount she bought and because she visits two days in a row you would multiply
Angle between 16 and 18 = 90 + 55 = 145°
<span>4k – 6 = -2k – 16 – 2
</span>4k+2k = – 16 – 2+6
6k=-12
k=-2
Hope this helps
Answer:
(c) 13.2
Step-by-step explanation:
The sum of angles in a triangle is 180°, so angle C is ...
C = 180° -A -B
C = 180° -16° -49° = 115°
The measure of side c can be found from the Law of Sines:
c/sin(C) = a/sin(A)
c = a·sin(C)/sin(A) = 4·sin(115°)/sin(16°)
c ≈ 13.2
