Answer:

76.7 million
89.1 million
75 million

Step-by-step explanation:

Let x represent the arrivals and departures at the third airport. Then the number at the first airport is x+1.7, and the number at the second airport is x+14.1. The total is ...

(x+1.7) + (x+14.1) + (x) = 240.8

3x +15.8 = 240.8

3x = 225

x = 75

x+1.7 = 76.7

x+14.1 = 89.1

The first airport has 76.7 million arrivals.

The second airport has 89.1 million arrivals.

The third airport has 75 million arrivals.

Answer:

The domain of g(x) is -3 to infinity

Step-by-step explanation:

Given

$g(x) = \sqrt{x + 3}$

Required

Determine the domain of g(x)

We start by expressing the content of the square root in the following form:

$x + 3 \geq 0$

Subtract 3 from both sides

$x + 3 -3 \geq 0 - 3$

$x \geq 0 - 3$

$x \geq - 3$

This can be expressed using interval notation as follows:

$\{x: -3, infiniti\}$

<em>Hence, the domain of g(x) is -3 to infinity</em>
