Answer:
v = 25
Step-by-step explanation:
The crucial information you need to know to solve this is to realize that HI and GH are the same length. However, why they are equal is not immediately obvious.
Both sides of the middle line (HF) are symmetrical, since G and I are the same distance away from the line, and they both lie on a line perpendicular to the middle line.
Note: we know they're the same distance away due to the small red marks in the lines, indicating that they're the same length.
The angles at G and I in the triangles are also the same, as the lines from G and I both meet at H. If they were different angles, they would each hit a different point on the middle line.
Thus, we can conclude that GH and HI are the same length.
Since we know the following:
GH = 4v - 75
HI = v
We can set GH and HI equal to each other and solve the equation.
4v - 75 = v
Subtract v from both sides:
3v - 75 = 0
Add 75 to both sides:
3v = 75
Divide both sides by 3:
v = 25
Answer: v = 25
Answer:
3.0233088 x 10 raise to power 7
Hey there!
The answer is 
To solve this we use subtraction, because "the difference" represents subtraction, so:

Now, we must find a common denominator, and we can see that
and
both go into
. To get to
, we multiplied the first fraction by 5 and the second by 6, so we now have:

This is equal to 
Hope it helps and have a great day!
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]
