Express the cartesian coordinates ( - 5,5) in polar coordinates in at least two different ways. write the point in polar coordinates with an angle in the range 0 < = theta < 2pi (type an ordered pair. type an exact answer, using pi as needed.) write the point in polar coordinates with an angle in the range - 2pi < = theta < 0. [ ] (type an ordered pair. type an exact answer. using pi as needed.)

one way) (r,θ) = (5,3/4π)

other way) (r,θ) = (5, 7/4*π)

Step-by-step explanation:

first way

x= r*cos θ

y= r*sin  θ

then

tg  θ = y/x → θ = tan ⁻¹ (y/x) = tan ⁻¹ (5/-5) = - tan ⁻¹ 1  = π- π/4 = 3/4π

then if

r=√(x²+y²)= r=√((-5)²+5²) = 5

therefore

(r,θ) = (5,3/4π)

another way would be

x= r*sin θ

y= r*cos  θ

then

tg  θ = x/y → θ = tan ⁻¹ (x/y) = tan ⁻¹ (-5/5) = - tan ⁻¹ 1  =  -π/4 or 2*π- π/4 = 7/4*π

then since r=5 , the polar coordinates would be

(r,θ) = (5, 7/4*π)

answer: 25.4 units

step-by-step explanation: radius = 12.7 units

diameter = twice the radius

diameter = 12.7 x 2

= 25.4

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
