Step-by-step explanation:
From the given information.
Since each players receives 5 cards; then = 5 * 4 = 20
Now, the process to go about this is to first select 5 cards out of 24 that goes to player 1. Then from the remaining 19, we can select another 5 cards that goes to player 2, etc. until 4 cards are left, out of which one is remained faced up.

∴
No fo ways =
= 1.19685 × 10¹⁶
Answer:
16. B
17. B
Step-by-step explanation:
16. The intercept form of the parabola is
where are two x-intercepts.
In your case,
so
To find <em>a</em>, substitute coordinates of the point (-6,-4) parabola is passing through
and
17. The vertex form of the parabola equation is
where <em>(h,k)</em> are the coordinates of the vertex and sign "-" because parabola goes down.
In your case, vertex is (2,3), so
The vertex is 3 units from the focus, then
The equation of the parabola is
