Answer:
4368 ways
Step-by-step explanation:
Use nCk for this. 16C5. This is
. This becomes
. This is
due to 16! and 5! canceling out. This becomes 4368.
Not possible. but degree of 3 would be (3x^2+5x) i think
The vertex is the minimum or the maximum point of the parabola.
<em>x and f(x) represent the horizontal and the vertical coordinates of the vertex.</em>

The standard form of a parabola is

The x coordinate of the parabola is calculated using:

The value of the x-coordinate is then plugged in, into the equation to calculate the y-coordinate, as follows:

At the end of the calculation,
x and f(x) represent the horizontal and the vertical coordinates of the vertex.
Take for instance:

The x-coordinate of the vertex is:




The y-coordinate is:



So, the vertex of
is (-1,11)

Answer:
Answers are (r,0) and (0,s)
Step-by-step explanation:
Given that in a rectangle ABCD, one vertex is the origin (0,0) A
The opposite vertex C is having coordinates as (r,s)
Since a rectangle has angle 90 we have x axis as one side and y axis as other side.
Length = r and width =s (since coordinates of C are (r,s))
Hence other coordinate B on x axis would be = (r,0)
and D on y axis = (0,s)
Answers are (r,0) and (0,s)
