The region is a segment of a circle with radius √2 lying above the line . In polar coordinates, this line has equation
and the circle has equation
The two curves meet when
Then the same integral in polar coordinates is
Choice C
(0,-2) is a point
put 0 into each equation and see if it gives you -2
A, c, d will give you -2
(2,0)
Only C gives you 0
Answer:8x^2-4x-5
Step-by-step explanation:just subtract
Answer:
D -13/35 ( negative 13/35 )
Step-by-step explanation:
4/5 + x = 3/7
Convert to equivalent fractions with a common denominator:
28/35 + x = 15/35
Subtract 28/35 from both sides
x = - 13/35
Converting from degrees to radians is actually very simple, it is a one-step unit conversion.
135° * π/180°= (135/180) π radians = 3π/4 radians= 2.3561944... thus: 2.35 is your answer.
