In how many distinguishable ways can you arrange the letters in the word CONNECTICUT? *
borishaifa [10]

Answer:

The number of distinguishable arrangements are 1,663,200.

Step-by-step explanation:

The word is: CONNECTICUT

The number of ways to arrange a word when no conditions are applied is:

\frac{n!}{k_{1}!\cdot k_{2}!\cdot k_{3}!...\cdot k_{n}!}

Here <em>k</em> is the number of times a word is repeated.

In the word CONNECTICUT there are:

3 Cs

2 Ns

2 Ts

And there are a total of <em>n</em> = 11 letters

So, the number of distinguishable arrangements are:

\frac{n!}{k_{1}!\cdot k_{2}!\cdot k_{3}!...\cdot k_{n}!}=\frac{11!}{3!\times 2!\times 2!}

                     =\frac{39916800}{6\times 2\times 2}\\\\=1663200

Thus, the number of distinguishable arrangements are 1,663,200.

An angle measures 120 degrees. Describe how to use special right triangles and the unit circle as tools to calculate the sine an
nalin [4]

Answer:

120 degrees is the right angle and the 30 degree added which is 1/3 here we know as we can always divide a side measure by 90 then multiply by a second angle to find the hypotenuse. When we do this we are using a three way system just like a three way system appears when we use a right angle triangle and read the functions.

Sin theta = 9/15. Find tan theta. A. 15/12. B. 9/12 C. 12/15 D. 12/9
Finger [1]

Answer:

B

Step-by-step explanation:

Sin \ theta = \frac{9}{15}=\frac{Opposite \ side}{hypotenuse}\\

Pythagorean theorem,

Adjacent side ² = hypotenuse² - opposite side²

                         = 15² - 9²

                          = 225 - 81

                          = 144

Adjacent side = √144 = √(12*12) = 12

Tan \ theta = \frac{opposite \ side}{adjacent \ side}= \frac{9}{12}
