A polar coordinate is that which can be written as (r, θ) where r is the radius and θ is the angle.
The radius, r, is also the hypotenuse of the right triangle that can be formed. Hence, it can be calculated through the equation,
r² = x² + y²
If we are to simplify this for the r alone, we have,
r = sqrt (x² + y²)
Substituting the known values,
r = sqrt ((4)² + (-4)²) = 4√2
The x and y can be related through the trigonometric function, tangent.
tan θ = y/x
To solve for θ
θ = tan⁻¹(y/x) = tan⁻¹(-4/4) = -45° = 315°
Hence, the polar coordinate is <em>(4√2, 315°)</em>
i was going to answer but siomeome beat me lol but hdjwStep-by-step explanation:
Side makes 846 because side = area to the power of 2
See in the explanation

We can write the Slope-Intercept form of the equation of a line as:
The slope is a measure of the steepness of a line It is a ratio between vertical change (run) and horizontal change (rise), so we can also write the slope (m) as:
We have the following facts:
- If we increase the rise, the slope also increases and if we decrease the rise the slope also decreases.
- If we increase the run, the slope decreases and if we decrease the rise the slope increases.

I think you mean mixed number fractions. So what you do is just subtract, both the fraction and also the number. So for example 1 2/3 - 1 1/3 is just 1/3 because you subtracted both of them
