Here we are dealing with combinations without repetitions.
Let's write the form of a name.
For names starting with W:
W _ _ _
For names starting with K:
K _ _ _
We are allowed to use only lettrs from F to X. That's total of 19 letters. We are not allowed to repeat letters so for each letter we can choose from one less available letters.
Let's start with names begining with W. We will write how man possible letters we can choose from.
W 18 17 <span>16
</span>At second possition we can choose from 18 letters because we must not repeat letters and W is placed in front of X in alphabet.
At third position we can choose from 17 letters becasue we already chose two of 19 possible letters.
At fourth position we can choose from 16 letters becasue we already chose three of 19 possible letters.
To calculate total number of possible names we need to multiply these numbers:
1 * 18 * 17 * 16 = 4896
Same calculation can be done for names starting with K. We would get same number as solution.
Total number of possible names starting with W or K is 4896 + 4896 = 9792
Answer:
When y=32, x=16.5
Step-by-step explanation:
Find x when y = 32, given that x varies inversely as y, and x = 132 when y = 4.
We are given:
x varies inversely with y
We can write it as: 
We have x = 132, when y=4
We can find value of k by using these values
We need to find x when y=32
So, when y=32, x=16.5
0.885 rounded to the nearest hundreds would be 0.89
When you read this, you immediately get this feeling that the answer is
(1 and 3/4) times (5) . The only problem is that it's kind of messy to
try and do the multiplication with (1 and 3/4) in that form, so it's a lot
easier if you change it to a different form ... you don't change the value
of the number, you just write it differently.
In place of (1 and 3/4), you could use 1.75 , or you could use 7/4 .
They're both exactly the same amount as (1 and 3/4), but they look
different, and they're easier to work with.
Since the problem wants the answer as a fraction or mixed number,
let's use 7/4 in place of (1 and 3/4).
OK. Five bags were used on Thursday, and (7/4) of that many were used
on Friday.
(7/4) x (5 bags) = <u>35/4</u> bags . . . . . That's the improper fraction.
The mixed number is (<u>8 and 3/4</u>) bags.

Answer: D) 5</h3>
Reason: It's the largest exponent
When a polynomial is written in standard form like this, the term with the largest exponent is written first, then the next largest and so on. So in cases like this, we simply need to look at the left-most term; however, this may not always be the case as your teacher could easily mix up the terms to make sure you're paying attention.
This is considered a quintic polynomial due to the degree of 5.
