<em>A function f (x) and g (x) then:</em>

<em>(f + g) (x) = x² - x + 6</em>

<em>Further explanation</em>

Like the number operations we do in real numbers, operations such as addition, installation, division or multiplication can also be done on two functions.

Suppose a function f (x) and g (x) then:

(f + g) (x) = f (x) + g (x)

(f + g) (x) is a new function of the sum of f (x) and g (x)

Likewise with other function operations:

(f-g) (x) = f (x) - g (x)

(fg) (x) = f (x) x g (x)

(f / g) (x) = f (x) / g (x)

In addition to the above operations we can combine two functions using the function composition with the symbol o

(fog) (x) = f ((g (x))

Known on the question

f (x) = x² + 1

g (x) = 5 x

Summing the two functions f (x) and g (x):

(f + g) (x) = f (x) + g (x)

(f + g) (x) = x² + 1 + 5 - x

(f + g) (x) = x² - x + 6

The ratio of the amount of vitamin A in cow milk to the amount of vitamin A in goat milk is
miv72 [106K]

Answer:

2080 IU

Explanation:

Given

Ratio of vitamin A in cow milk to goat milk = 3 : 4

Required

Determine the content of vitamin A in goat milk if cow milk has 1560 IU

The given parameters shows a direct proportion.

Let G represents Goat and C represent Cow

Given that there exists a direct proportion;

C = K * G where K represents the constant of proportionality.

Solving for K when C = 3 and G = 4

C = K * G becomes

3 = K * 4

3 = 4K

Divide through by 4

¾ = K

K = ¾

Now, solving for G given that C = 1560IU;

We'll make use of the same formula as above

C = K * G

Substitute 1560 for C and ¾ for K; the expression becomes

1560 = ¾ * G

Multiply both sides by 4

4 * 1560 = 4 * ¾ * G

6240 = 3 * G

Multiply both sides by ⅓

⅓ * 6240 = ⅓ * 3 * G

2080 = G

G = 2080

Hence, the vitamin A in the goat milk is 2080IU

Vladimir [108]

Encryption protects sensitive information is explanation best explains the importance of using encryption. Personal information and important information are protected, and communication between client apps and servers is made more secure.

<h3>What is Encryption?</h3>

Encryption is a way of securing digital data that employs one or more mathematical procedures, as well as a password or "key" to decrypt the information.

Data is encrypted using an algorithm that makes the original data unreadable. The name of two different data comes from the fact that encryption and decryption are done with the same key.

Thus option C is correct.

Muriel told shana that one of the products in the table was incorrect. Which value in the table is incorrect? what is the value
IRISSAK [1]

The product of expressions or numbers is calculated by multiplying the expressions or numbers.

  • The incorrect value in the table is -2y
  • The value that should have been written is -2xy

From the table (see attachment), the incorrect product is given as:

-y \times 2x = -2y

The above product is incorrect.

This is so because when -y is multiplied by 2x, the result is -2xy

So, the correct expression is:

-y \times 2x = -2xy
