Answer:
There’s no answer
Step-by-step explanation:
A function can be represented by equations and tables
- 4 users are logged in by 9am
- The domain is [3,23] and the range of the function is [3,4]
<h3>The number of users at 9am</h3>
The function is given as:

At 9am, x = 9.
So, we have:


Simplify

Approximate

Hence, 4 users are logged in by 9am
<h3>The domain</h3>
Set the radical to 0

Solve for x

The maximum time after midnight is 23 hours.
So, the domain is [3,23]
<h3>The range</h3>
When x = 3, we have:


When x = 23, we have:

So, the range of the function is [3,4]

Answer:

Step-by-step explanation:

3.906m
Step-by-step explanation:
from the topic angle of elevation and depression
putting down the above question diagrammatically
we have a triangle
The angle of elevation pad looking up = 38°
using the tangent rule TOA
TAN∅= OPPOSITE/ADJACENT
we have
tan 38° = x/5
x= tan 38° × 5
x= 0.781 * 5
x = 3.906m
