Slope is 2 and y-intercept is 9
Answer:
1st option
Step-by-step explanation:
the area of the shaded portion is calculated as
area of sector - area of white Δ
area of sector = area of circle × fraction of circle
= πr² × 
( r is the radius )
= π × 8² × 
= 64π ×
= 16π in²
area of Δ = 
bh ( b is the base and h the perpendicular height )
here b = h = 8
area of Δ = × 8 × 8 = × 64 = 32 in²
then
area of shaded portion = (16π - 32 ) in²
Answer:
The graph y = 18x2 + mx + 2= 12
So the answer is 12
Answer:
P(1, π/4)
P(-1, π/4)
P(4, 5π/6)
P(-4, 5π/6)
Step-by-step explanation:
Knowing the formulas
r = √(x²+y²)
θ = Arctg (y/x)
we have
a) P(1, 1)
i)
r = √(1²+1²) = +1
r = +1
θ = Arctg (1/1) = π/4
P(1, π/4)
ii) r = √(1²+1²) = -1
r = -1
θ = Arctg (1/1) = π/4
P(-1, π/4)
b) P(2√3, -2)
i)
r = √((2√3)²+(-2)²) = +4
r = +4
θ = Arctg (-2/2√3) = 5π/6
P(4, 5π/6)
ii)
r = √((2√3)²+(-2)²) = -4
r = -4
θ = Arctg (-2/2√3) = 5π/6
P(-4, 5π/6)
So when you are trying to tell the difference between something, you need to find the difference through subtraction! 6 1/6 - 4 5/6 = 1 1/3. :) I hope this helps!
