Answer:
D
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ( where r is the radius )
Here r = 15, thus
x² + y² = 15² , that is
x² + y² = 225 → D
Answer:
1:2.33
Step-by-step explanation:
Divide 107.8 by 46.2 to get how much 107.8 equals when 46.2 equals 1. you get 1:2.33.
I think the answer is B Mean or median because there is no outlier.
Answer would be D You can have a rational discriminant for an irrational root, but you can also have rational discriminant for a rational root. So C is partially correct.
<span>All prime discriminants will result in an irrational root, but not all irrational roots have prime discriminants </span>
