The inequality sin is less than or equal to so the line will be continuous (not dashed).
So its not graph 1 or 2.
And, as its less than, the shading will be under the line
Answer - Graph 3.
Answer:
Center:-1,-2
Radius: 2
Step-by-step explanation:
Ok, get the form of a circle from this equation-
(x+2)^2+(y+2)^2=4
Since this is the form of a circle, I can figure out the center and the radius from here,
r=2
h=-1
k=-2
Center:-1,-2
Radius: 2
6 feet * 7 feet = 42 feet²
18 feet * 21 feet = 378 feet²
42 feet² was painted for $52
1 feet² will be painted for $52/42
378 feet² will then be painted for: ($52/42) * 378
= $468
Hence 18 feet by 21 feet will be painted for $468
Hope this helps.
