well, the recursive rule of aₙ = aₙ₊₁ + 7, where a₁ = 15, is simply saying that
we start of at 15, and the next term is obtained by simply adding 7, and so on.
well, that's the recursive rule.
so then let's use that common difference and first term for the explicit rule.

Given a quadratic equation 
, we define the discriminant as
The number of real solutions of the equation depend on the sign of 
:
- If
the equation has two solutions - If
the equation has one double solution - If
the equation has no real solutions
In this case, we have
And so this equation has no real solutions.
Answer:
= 2 pi x^3
Step-by-step explanation:
radius = x
h = 2x
The volume of a cylinder is
V = pi r^2 h
= pi ( x) ^2 ( 2x)
= 2 pi x^3
