Make into equation
Y = 1/3x - 2
-5 = 1/3(-1) - 2, false
-1 = 1/3(3) - 2, true
Answer: (3,-1) is also on the line
The domain is the set { -2, 0, 2, 3}
discussion:
the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives -2, 0, 2, 3.
Solution (1) using angles of sectors:
Area of A = pi r^2 x 90/360 = 4.9
Area of B = pi r^2 x 270/360 = 14.2
Check: Area of A/B = 4.9/14.72 = 1/3 (as given)
Solution (2) using given info:
Area of B + Area of A = area of circle
Area of B + 1/3 Area of B = 3.14 * (2.5)^2 = 19.625
4/3 Area of B = 19.625
Area of B = 3/4 * 19.625
Area of B = 14.72
Area of A = 1/3 * 14.72 = 4.9
There is more solutions to this problem , like polar coordinate integration , and so on. for more just request.
28/4 = 7...and since the price fell, it would be -7 per day
Answer:
No coz 2:3 is 2+3=5
1:2 is 1+2=3 so they are not equivalent.
