Answer:

x times 2

Step-by-step explanation:

the unknown in this problem is the amount of time Jake spent studying. What we do know, is that Julie spent 2 times as long as Jake has. So you take Jake's time and multiply it by 2 sice Julie studied twice as long.

there are 6 times as many ways to arrange the letters in the word "sleeplessness" as there are to arrange the letters in the wor
EastWind [94]

Using arrangements of words, it is found that the statement is true.

------------------

  • Suppose a word has n letters.
  • Considering that m of these letters are repeating, each n_1,n_2,...,n_m times.
  • The number of distinct ways the word can be arranged is given by:

N = \frac{n!}{n_1\times n_2 \times ... n_m}

------------------

  • The word "sleeplessness" has 13 letters.
  • s repeats 5 times.
  • e repeats 4 times.
  • l repeats 2 times.

Thus, the number of ways to arrange the letters is given by:

N_1 = \frac{13!}{5!4!2!}

------------------

  • The word "senselessness" has 13 letters.
  • s repeats 6 times.
  • e repeats 4 times.
  • n repeats 2 times.

Thus, the number of ways to arrange the letters is given by:

N_2 = \frac{13!}{6!4!2!}

------------------

Finding the ratio of N_2 to N_1:

\frac{N_2}{N_1} = \frac{\frac{13!}{5!4!2!}}{\frac{13!}{6!4!2!}} = \frac{13!}{5!4!2!} \times \frac{6!4!2!}{13!} = \frac{6!}{5!} = 6

Thus, since the ratio is 6, the statement is true.

If f(x) = 3x^2 and g(x) = x+2 find (f•g)(x)
Alex777 [14]

Answer:

(f*g)(x) = 3x^3 + 6x^2

Step-by-step explanation:

Since we are looking for the result of multiplying the equations (f*g), we must multiply the right sides together

(f*g)(x) = (3x^2)(x+2)

To get from here to the solutions, we must multiply the first term by all parts in the second term

3x^2 * x = 3x^3

3x^2 * 2 = 6x^2

from there, just put them back in the equation

(f*g)(x) = 3x^3 + 6x^2
