How many strings of five English letters that start with two consecutive vowels (A,E,I,O, or U) have no repeated letters

Answers

Answer 1

Answer:

242880

Step-by-step explanation:

In the English alphabet, we have 5 vowels. To form a string of 5 English letters in which it starts with two consecutive vowels; then we have the following.

                                           

In the first space, 5 vowels are possible.

in the second space, 4 vowels are possible since there is no room for repetition of letters.

Now, the total number of ways of assigning two distinct vowels in the first two spaces = 5 × 4 = 20

From the question, since it is said that the letter starts with two consecutive vowels, it implies that starting from the third letter, it can be filled with all the remaining alphabet, be it a vowel or consonant.

Thus, the remaining alphabet = 26 - 2 = 24 alphabets to fill the 3 remaining spaces, which can be achieved in 24P3 ways.

P(24,3) = 24!/(24-3)!

P(24,3) = 24!/21!

P(24,3) = 24 × 23 × 22 × 21! / 21!

P(24,3) = 24 × 23 × 22

P(24,3) = 12144 ways

Thus, the total number of strings of five  English letters that start with two consecutive vowels without having repeated letters is:

= 5  × 4  ×  24 × 23 × 22

= 242880

 5        4        24          23       22

I think they are asking the area of the triangle so we are going with that.

Step-by-step explanation:

Easiest way to do this is find the area of the incomplete square, and then cut that in half for the triangle.

so it is 4 cm wide

and 8 cm tall

length x width = area

8 x 4 = 32

32/2 = 16

So your answer should be 16 cm

What is the slope of the linear function in decimal form?

Answers

Answer:

Slope = 0.6

Step-by-step explanation:

Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

By applying this rule in the table attached,

Let the two points are (35, 94) and (45, 88) through which the graph of a linear function is passing.

Slope of the linear graph = [tex]\frac{94-88}{45-35}[/tex]

                                          = [tex]\frac{6}{10}[/tex]

                                          = 0.6

Therefore, slope of the linear function is 0.6

Find all exact solutions on [0, 2π). (Enter your answers as a comma-separated list.)
tan(x) − 2 sin(x) tan(x) = 0.

Answers

Answer:

[tex]0, \dfrac{\pi}{6}, \dfrac{5\pi}{6}, \pi[/tex]

Step-by-step explanation:

Given the equation:

[tex]sin(x)-2sin(x) tan(x)=0[/tex]

To find:

The solutions of given equation in the range [0, 2[tex]\pi[/tex]) i.e. 0 can be in the answer but [tex]2\pi[/tex] can not be there in the answer.

Solution:

Taking [tex]tan(x)[/tex] common, we get:

[tex]tan(x) (1-2sin(x))=0[/tex]

The solutions can be given as:

[tex]tan(x) = 0[/tex] OR [tex]1-2sin(x) = 0[/tex]

Let us solve both the equations one by one:

First equation:

[tex]tan(x) = 0\\ \Rightarrow x=0, \pi[/tex]

Second equation:

[tex]1-2sin(x) = 0\\\Rightarrow 2sinx=1\\\Rightarrow sinx=\dfrac{1}{2}\\\Rightarrow x = \dfrac{\pi}{6}, \dfrac{5\pi}{6}[/tex]

Therefore, the answers as a comma separated list are:

[tex]0, \dfrac{\pi}{6}, \dfrac{5\pi}{6}, \pi[/tex]

Answers

A kitchen sink faucet

Step-by-step explanation:

0.5 gallon of water × 6 = 3 gallons

10 second × 6 = 60 seconds = 1 minute

 

0.75 gallon of water × 4 = 3 gallons

18 seconds × 4 = 72 seconds = 1 minute 12 seconds

1 minute is faster than 1 minute and 12 seconds by 12 seconds

so a kitchen sink faucet

Is 56 × 19/20 greater than or less than 56?

Answers

Answer:

Less

Step-by-step explanation:

56 is multiplied by 19/20 which is obviously less than one

Answer:

Step-by-step explanation:

56/60 = 0.9333

19/20 = 0.95

Now that these fractions have been converted to decimal format, we can compare the numbers to get our answer. 0.9333 is NOT greater than 0.95 which also means that 56/60 is NOT greater than 19/20.

Hopefully this tutorial has helped you to understand how to compare fractions and you can use your new found skills to compare whether one fraction is greater than another or not!

Given cubic equation is:

x³ + 6x² + 12x + 8 = 0

⇒ x²(x + 2) +4x(x + 2) + 4(x + 2) = 0

⇒ (x + 2)(x² + 4x + 4) = 0

⇒ (x + 2)(x + 2)²  = 0

⇒ (x + 2)³ = 0

⇒ x = -2
