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)
(0,0)(12,84)
slope = (84 - 0) / (12 - 0) = 84/12 = 7
it goes thru the origin (0,0) therefore, the y int = 0
In y = mx + b form, the slope will be in the m position and the y int will be in the b position.
ur equaton is : y = 7x + 0, which can also be written as y = 7x <==
Answer:
69 420
Step-by-step explanation:
we are given
For finding inverse function , we do following steps
step-1:
Set f(x)=y
step-2:
Switch x and y
step-3:
now, we can solve for y
Multiply both sides by 9y-2
Add both sides by 2x
now, we can divide both sides by 9x
so, we get inverse function as
