Answer:

16x^(4/5)

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

Step-by-step explanation:

While you don't specifically state what you're supposed to do with this expression, it's an easy guess that you want to rationalize the denominator.

Let's write it as

------------ . We want to eliminate the radical from the denominator.

x^(1/5)

To accomplish this, multiply numerator and denominator by x^(4/5). Note that [x^(1/5)][x^(4/5)] = x^1 = x, which is what we want for the new denominator.

We end up with:

16x^(4/5)

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

How do I solve this?? I'm lost

Alekssandra [29.7K]

Your insight that the function values differ by 5 every time is very important. So your f(x) will contain 5x as a term. You have to find a constant to add or subtract to make sure f(1)=-2.

f(x) = 5x-7 does the job.

A jar of alphabet tiles contains 10 unique consonant tiles and 5 unique vowel tiles.

vladimir2022 [97]

Answer: Probability that 3 are consonants and 2 are vowels is 0.3996.

Step-by-step explanation:

Since we have given that

Number of unique consonant tiles = 10

Number of unique vowel tiles = 5

Total number of tiles = 10+5=15

we need to pick 5 tiles randomly,

So, Probability that 3 are consonants and 2 are vowels is given by

$\frac{^{10}C_3\times ^5C_2}{^{15}C_5}\\\\=\frac{\frac{10\times 9\times 8}{3\times 2\times 1}\times \frac{5\times 4}{2\times 1}}{\frac{15\times 14\times 13\times 12\times 11}{5\times 4\times 4\times 3\times 2\times 1}}\\\\=0.3996$

Hence, Probability that 3 are consonants and 2 are vowels is 0.3996.

Which of the following values cannot be probabilities? 3/5, 5/3, 0, 1, 1.15, StartRoot 2 , -0.57, 0.09

Ugo [173]

Answer:

$\sqrt{2},-0.57$

Step-by-step explanation:

Probability of any incidence can only be a rational number.

Porbability can never be less than zero. It is basically defined as the ratio of

chance of occurence of an event to the total possible ways of occurence of the event. So an event cannot occur and the probability can be zero but never negative.

$\sqrt{2}$ being a irrational number cannot be a possibkle vlue for probability.

Hence values which cannot be possible are $\sqrt{2},-0.57$ .

Given: The

AlekseyPX

Answer:

Step-by-step explanation:

We can calculate for a using sine rule.

For angle A,

A + 27° + 82° = 180 ( sum of angles in a triangle).

A + 109 = 180

A = 180 - 109 = 71°

Therefore,

A = 71°

calculating for side a

$\frac{sin \: 27}{12} = \frac{sin71}{a} \\ a = \frac{12 \times sin71}{sin27} \\ a \: = \frac{11.346}{0.454} \\ a = 25$
