Answer:
To find the polar coordinates (r, θ) of the point (-2√3, 2), you can use the following formulas:
r = √(x^2 + y^2)
θ = arctan(y / x)
In this case:
x = -2√3
y = 2
Let's calculate r and θ:
r = √((-2√3)^2 + 2^2)
r = √(12 + 4)
r = √16
r = 4
Now, calculate θ:
θ = arctan(2 / (-2√3))
First, find the angle in radians from the arctan:
θ = arctan(-√3)
θ ≈ -π/3 (in radians)
So, the polar coordinates of the point (-2√3, 2) are approximately (4, -π/3) in radians.

Answer:
$14
Step-by-step explanation:
x/17.5=20/100, do the butterfly method
17.5x20=350
350/100= 3.5
17.5-3.5=14
Answer:14.00
Step-by-step explanation:
17.50*80/100 = 14.00
