Because they have like-exponents (the exponents of the x is the same number, x^6) you can treat both values sort of like whole numbers. 512x^16 + 1x^16 making it 513x^16. Same thing with the y, it should be 1y^14+ 1y^14 = 2y^14
You need to convert the cartesian coordinates to polar: This means we need to go from (x, y) --> (r, angle)
We can covert, using the following formulas:
Find r:



r = 4
Now, find our angle:
Use the inverse of tan

Turn 30 degrees to radian

Answer =
= C

Step-by-step explanation:
Answer is .325 hope it helps
Ratio of the heights of two similar cones is 7/9
what is the ratio of their radii? ratio of their volumes??
TIA
If they are similar, the ratio of the radaii is the same.
Now consider that the volume of a cone is 1/3 PI r^2 * h
So the volume ratio will have a (7/9)^2 * 7/9 ratio
