The solution to this problem is y raised to the 4th power.

Answer: 10,080</h3>
Explanation:
There are 8 letters so there are 8! = 8*7*6*5*4*3*2*1 = 40,320 permutations of those letters. However, the letters "O" and "L" show up twice each, so we must divide by 2! = 2*1 = 2 for each instance this happens.
So,
(8!)/(2!*2!) = (40,320)/(2*2) = (40,320)/4 = 10,080
is the number of ways to arrange the letters of "football".
The reason we divide by 2 for each instance of a duplicate letter is because we can't tell the difference between the two "O"s or the two "L"s. If there was a way to distinguish between them, then we wouldnt have to divide by 2.
Answer:
Tan30° = 4/y
Tan30° = 1/root3
Therefore 4/y = 1/root3
Which gives the value of y 4root3
Which is 6.92 (approx)
As for x
Sin30 =4/x
1/2=4/x
X=8
Yes because i took this in economics class
