Which of the following is a composite number?

2 answers:

8 0

A composite number is a number that can be divided evenly by numbers excluding 1 and itself.

29 is a prime number because it is divisible by only one and itself, so A is not the correct answer.

29/29 = 1 | 29/1 =29

13 is a prime number because it is divisible by only one and itself, therefore, B is not the correct answer.

13/13=1 | 13/1=13

91 is a composite number because it is divisible by 1, 7, and 91.

Hope this helps! :)

The inverse function of f(x) is $f^{-1}(x) = \sqrt{x - 6}$ and the domain is x > 6

<h3>How to determine the inverse function?</h3>

The function is given as:

f(x) = x^2 + 6

Rewrite as:

y = x^2 + 6

Swap x and y

x = y^2 + 6

Subtract 6 from both sides

y^2 = x - 6

Take the square root

$y = \sqrt{x - 6}$

Rewrite as:

$f^{-1}(x) = \sqrt{x - 6}$

Hence, the inverse function of f(x) is $f^{-1}(x) = \sqrt{x - 6}$ and the domain is x > 6

BE is parallel to CD.

Viktor [21]

Answer:

CD = 8 cm

Step-by-step explanation:

Given

See attachment

$AE=6 cm,\ ED=4 cm,\ AB=4.5 cm,\ BE=4.8 cm.$

Required

Find CD

To calculate CD, we first calculate BC using the following equivalent ratio

$AB : BC = AE:ED$

Substitute values for AB, AE and ED

$4.5 : BC = 6 : 4$

Express as fraction

$\frac{4.5 }{ BC} = \frac{6 }{ 4}$

Cross Multiply

$BC * 6 = 4.5 * 4$

$BC * 6 = 18$

Divide through by 6

$BC = 3$

To calculate CD,

We make use of the following equivalent ratio

$AB : BE = AC : CD$

Where

$AC = AB + BC$

$AC = 4.5 + 3$

$AC = 7.5$

So, we have:

$AB : BE = AC : CD$

$4.5 : 4.8 = 7.5 : CD$

Express as fraction

$\frac{4.5 }{ 4.8 }= \frac{7.5 }{ CD}$

Cross Multiply

$4.5 * CD = 7.5 * 4.8$

Divide through by 4.5

$CD = \frac{7.5 * 4.8}{4.5}$

$CD = \frac{36}{4.5}$

$CD = 8$
