Answer:
28%
Step-by-step explanation:
Here is the missing table from the question:
Speed (mph) Number of Vehicles
36-40 2
41-45 14
46-50 18
51-55 12
56-60 4
Given: A police officer records the speeds of vehicles on a road.
Now, finding the percent of vehicles traveling between 41 and 45 miles per hour.
First, calculating the total number of vehicles.
Total vehicles= 
Vehicles travelling at speed of 41-45 mph= 14
Formula; percent of vehicles traveling between 41 and 45 mph= 
⇒ Percent of vehicles traveling between 41-45 mph= 
∴ Percent of vehicles traveling between 41-45 mph is 28%
Answer:
-x² - 9 is your simplified form
Step-by-step explanation:
Combine terms with the same amount of variables.
(2x² - 5) - (3x² + 4)
First, distribute the negative sign to all terms within the second parenthesis
(2x² - 5) - 3x² - 4
Combine like terms
2x² - 3x² = -x²
-5 - 4 = -9
-x² - 9 is your simplified form

The function represented by the table is linear function
and pass with (0,0)
so it is in the form
f(x) = m x
where m is the slope
m = [ f(x₂) - f (x₁) ] / [ x₂ -x₁]
(4-0)/(1-0) =4
so
f(x) = 4 x
