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:
pls give brainlist
Step-by-step explanation:
a.  50 x 9 = 450. A=450
  50 x 9 = 450. A=450
b. I can scale the unit rate of the area given above and largen the area of the map. Ex.  =
= <---(scaled by 2)
 <---(scaled by 2) 
Then we can enlarge it however we want so,
 =
 =  <--(scaled by 2 once more)
  <--(scaled by 2 once more)
If the statement above is true then we can scale times 4.
  =
=  <---(scaled by 4)
 <---(scaled by 4)

Answer:
Probability that the cost will be less than $500 is 0.95994 .
Step-by-step explanation:
We are given that Money magazine reported that a visit to a hospital emergency room for something as simple as a sore throat has a mean cost of $348 with a standard deviation of $87.
Let X = cost of a hospital emergency room visit for this medical service
So, X ~ N( )
)
The standard normal z score distribution is given by;
               Z =  ~ N(0,1)
 ~ N(0,1)
(a) Probability that the cost will be less than $500 = P(X < $500)
     P(X < 500) = P(  <
 <  ) = P(Z < 1.75) = 0.95994 {from z table}
 ) = P(Z < 1.75) = 0.95994 {from z table}
Therefore, the probability that the cost will be less than $500 is 0.95994 .
                                                
 
        
             
        
        
        
Option A is correct.
If we evaluate the function at  , i.e. at the beginning, we have
, i.e. at the beginning, we have

with each minute, you multiply the current number of cell by 2, so they double every minute.
Option B is incorrect, because if the number of cells increases by 2 every minute, the function would be

Option C is incorrect, because after one minute (i.e. when x=1) we have

cells, so 75 is not the number of cells after one minute
Option D is incorrect in both the initial value and the behaviour of the function
 
        
             
        
        
        
Answer:
3.333
C = 3.3333g
Step-by-step explanation:
Given the relation : C = rg
C = Total cost of gasoline
g = Number of gallons of gasoline used
r = constant of proportionality
Picking any point on the graph :
At cost, c = $30
Number of gallons of gasoline used, g = 9
Putting the values into our equation :
C = rg
$30 = r * 9
30 = 9r 
Divide both sides by 9
30/9 = 9r / 9
3.333 = r 
Hence, constant of proportionality, r = 3.333
