Answer:
The answer is B ⇒
Step-by-step explanation:
∵ v = π r² h
∴ r² =
∴ r =
∵ r = 10 ft and h = 15 ft
∴

This is a polynomial of degree 2, and remember that complex roots always come in pairs; therefore, in a second degree polynomial you can only have 0 real roots and 2 complex roots, or 2 real roots and 0 complex roots. There is no way you can have 1 real root and 1 complex root because, as stated before, complex (non-real) roots always come in pairs; so the only way of having 1 real root is dumping the polynomial of degree 2 (
) by changing the 14 to 0. That way we'll left with 
which only has one real root:
Answer:
Step-by-step explanation:
Please see the picture below.
1. Given the function f(x) = |x|, applying a vertical stretch with scale factor , we have the transformed function:
2. Applying a translation of 3 units to the right, we have:
3. Finally applying a translation down of 1 unit, we have:
The standard form of a parabola is
So, if you expand the square, you get
which is the standard form
