What is the domain of f(x) = √x – 4 over the set of real numbers?

nikklg [1K]

Answer:

(2) x $\geq \\$ 4

Step-by-step explanation:

Given the sqrt(x), x $\geq \\$ zero

So, given sqrt(x -4), x -4 $\geq \\$ 0

Now solve for x

x - 4 $\geq \\$ 0

x $\geq \\$ 4

A local library claims it has 2.73x103 books. If there are 42 people in the building, how many books per capita are there?

Marizza181 [45]

Answer:

63 books per capita in the library

Step-by-step explanation:

Given

$Books = 2.73 * 10^3$

$People = 43$

Required

Determine the book per capita

To do this, we simply divide the number of books by number of person;

$Average = \frac{Books}{People}$

$Average = \frac{2.73 * 10^3}{43}$

$Average = \frac{2.73 * 1000}{43}$

$Average = \frac{2730}{43}$

$Average = 63.488372093$

$Average = 63$ (Approximated)

Hence;

There are 63 books per capita in the library

Find the values of x and y. 40 sy 40 xº X = y= 0

Helga [31]

Answer:

x = 30°

y = 5

Step-by-step explanation:

The ∆ where you find x is an isosceles ∆ because two of its sides has a length of 40 each, since the other triangle has equal angles of 60° each, it also has equal length sides of 40.

Therefore, x is a base triangle of the isosceles, thus:

x = ½(180 - (180 - 60))

x = ½(180 - 120)

x = ½(60)

x = 30°

Let's find y.

8y = 40 (sides of an equilateral ∆ are equal)

Divide both sides by 8

y = 5
