What is the reciprocal of -9/11?

Answers

The reciprocal of -9/11 is 11/-9. When using the reciprocal you must always flip the fraction. I'll give some examples:
2/3 is 3/2
4/9 is 9/4
1/16 is 16/1
I hope this helps you!

the reciprocal of a fraction is the same tying flipped so the reciprocal of -9/11 is 11/-9

Find a real number c such that x^(2)+12x+c is a perfect square trinomial.

Answers

Answer:

The value of c is 36

Step-by-step explanation:

Now, we fine the perfect square polynomial, we need to have the expression of the form:

$a^2+b^2+2ab$

so this can be written as a perfect square as: $a^2+b^2+2ab= (a+b)^2$

Now the expression given to us is:

$x^(2)+12x+c$

so when c is 36, we will get:

$x^(2)+12x+c= x^(2)+12x+36$

Now, this can be re-written as:

$x^(2)+2*6*x+6^2$

so here we can see that it is of the form:

$a^2+b^2+2ab$

so the perfect square is:

$x^(2)+2*6*x+6^2= (x+6)^2$

Hence, when c = 36 we get a perfect square.

There are 30 flavors and you can mix up to 3 of them. How many flavor possibilities are there? You can't mix the same flavors more than once in one drink. Show your work.

Answers

$^(30)C _(3) = (30!)/((30 - 3)!3!) \n = (30!)/(27! * 3!) \n = (30 * 29 * 28 * 27 * 26 * 25 * . . .* 3 * 2 * 1)/(27 * 26 * 25 * . . . * 3 * 2 * 1* 3 * 2 * 1) \n =5 * 29 * 28 \n =4060$
There are 4060 flavor possibilities.
