Let a set of n elements. 
We can find n! (factorial) of the n element. 
However, combination of the element lead to less than n! possibilities. 
(combining like adding or multiplying)
So the proposition is false.

Answer:

False; you would have more permutations than combinations.

Step-by-step explanation:

The formula for taking combinations of <em>n</em> objects taken <em>r </em>at a time is

\frac{n!}{r!(n-r)!}

The formula for taking permutations of <em>n</em> objects taken <em>r</em> at a time is

\frac{n!}{(n-r)!}

Comparing these two, we can see that the difference between the formulas is that the formula for combinations is divided by an extra r!.  Since it is divided by a larger number, it will result in a smaller answer; therefore permutations give more results than combinations.

ABCD is a parallelogram and line CD = line DA. determine whether the parallelogram is a rhombus. if so by which property?
tekilochka [14]
Since it tells you it's a parallelogram you know that opposite sides are parallel.
The other piece of information we are given is a pair of consecutive congruent sides. If these sides are congruent the other sides must also be congruent.

Use the fundamental identities to simplify the expression.<br> 9tantheta9cottheta/9sectheta
Mnenie [13.5K]
[9tan(θ) * 9cot(θ)] / 9sec(θ)

First cancel out the 9's:

tan(θ)cot(θ)/sec(θ)

Recall the following trig identities:

tan = sin/cos

cot = cos/sin

sec = 1/cos

Thus, we can rewrite the expression as:

[ (Sin(θ)/cos(θ)) *(cos(θ)/sin(θ)) ] / (1/cos(θ))

In the numerator, the sine's and cosine's cancel each other out:

1 / (1/cos(θ))

which we can rewrite as cos(θ).
