A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the objects. The polar coordinate of the coordinate (1, -3) is (√10, 288.435).
<h3>What are coordinates?</h3>
A coordinate system in geometry is a system that employs one or more integers, or coordinates, to define the position of points or other geometric components on a manifold such as Euclidean space.
The polar coordinate of the coordinate (1, -3) are,
r = √(x² + y²) = √[(1)²+(-3)²] = √10
θ = tan⁻¹(-3/1) = -71.565 = 288.435
Hence, The polar coordinate of the coordinate (1, -3) is (√10, 288.435).

Answer:
2.5
Step-by-step explanation:
The graph shows the curve extends downward to y = 2.5 in several places.
2.5 is the minimum value
_____
<em>Additional comment</em>
In this case, we assume the arrows at the ends of the curve mean the curve continues in the same fashion (same period and amplitude) as the part shown. For some graphs, arrows at the ends of the curve mean the graph extends to infinity in that direction.
Answer:
254 inches squared
Step-by-step explanation:
Hi there!
where r is the radius of the circle
The radius is equal to half the diameter. Given that the diameter is 18 inches, we know that the radius of the circular plate is 9 inches. Plug this into the equation:
Therefore, the area of the plate is approximately 254 inches squared.
If this is not an answer choice, the question may have been asking for the radius of the circle rather than the area.
I hope this helps!
His distance is 13 kilometers.
His displacement is √41 km, in a direction that's roughly northwest.
That's 6.403 km in the direction 38.7° north of west .
