What are the polar coordinates?
What are polar coordinates of (√2, 1)? Solution: Here we need to convert from rectangular coordinates to polar coordinates: P = (x, y) = (r, θ) r = ± √(x^2 + y^2); tan θ = y/x or θ = arc tan (y/x) So we have: P = (√2, 1) r = ± √[(√2)^2 + 1^2] = ± √3 θ = arc tan (y/x) = arc tan (1/√2) = arc tan (√2/2) ≈ 35.3°, which is one possible value of the angle. (√2, 1) is in the Quadrant I. If θ = 35.3°, then the point is in the terminal ray, and so r = √3. Therefore polar coordinates are (√3, 35.3°). Another possible pair of polar coordinates of the same point is (-√3, 215.3°) (180° + 35.3° = 215.3°). Edit: Note the negative in the r value.

What coordinates will the point 3-2 reflected over the line yx have?
To reflect a point over the line ( y = x ), you swap its x-coordinate and y-coordinate. For the point ( (3, -2) ), the reflection over the line ( y = x ) results in the point ( (-2, 3) ). Therefore, the coordinates of the reflected point are ( (-2, 3) ).
What is the coordinates when reflect over x axis?
When a point with coordinates ((x, y)) is reflected over the x-axis, its new coordinates become ((x, -y)). This means that the x-coordinate remains the same while the y-coordinate changes its sign. For example, if the original point is ((3, 4)), its reflection over the x-axis would be ((3, -4)).
What are 2 polar coordinates for the point -3 -3?
The point whose Cartesian coordinates are (-3, -3) has the polar coordinates R = 3 sqrt(2), Θ = -0.75pi.
A point is located at 2,-3 if you reflected that over the x-axis what would the new coordinates be?

What are the coordinates of point a after being dilated by a factor of 3?
To find the coordinates of point A after being dilated by a factor of 3, you multiply the original coordinates (x, y) of point A by 3. For example, if point A has coordinates (2, 4), the new coordinates after dilation would be (2 * 3, 4 * 3) or (6, 12). Thus, the coordinates of point A after dilation depend on its original position.
What is the correct arc length for arc welding?

Which set of rectangular coordinates describes the same location as the polar coordinates (3sqrt2,5pi/4)?
(-3,-3)
If arc gbd is 280 what is the measure of angle 3?
To determine the measure of angle 3, we need more context about the relationship between arc gbd and angle 3. If angle 3 is an inscribed angle that subtends arc gbd, then the measure of angle 3 would be half the measure of arc gbd. Therefore, if arc gbd is 280 degrees, angle 3 would measure 140 degrees.
What are the 3 coordinates in cartesian plane?
You do not have 3 coordinates in the Cartesian plane. The Cartesian plane is a plane and is therefore 2 dimensional. In 2 dimensional space you require only 2 coordinates. 3 coordinates are required to locate a point in 3-dimensional space but then it cannot be a Cartesian PLANE.
