Answer:
Denmark has the greatest population density, While the USA has the least density population
Step-by-step explanation:
When Calculating Population Density you use d = p/a
Which would make the USA density population
USA
29.12 = 272,648,000 / 9,364,520
Denmark
124.72 = 5,248,000/42,077
Ghana
77.21 = 18,339,000/237,533
Where D is the density, P is the population, A = the area.
The equation shown on the table is y=2x
We are looking to find the point where the curve discontinued
Step 1: Factorise both numerator and denominator (if possible)
Step 2: Recognise the common factor, which is
Step 3: Equate the common factor to 0
Answer: -5
So when one goes up, the other goes down. This is an inverse equation.
An inverse equation looks like this: y = 1/x
In this case, when parking fee (f) decreases, cars (c) increase.
You know which side to put each variable on using the chart they gave you.
f | c
20.00 15 (20.00 = x/15) x=300
30.00 10 (30.00 = x/10) x=300
So your equation in this case is f = 300/c
Knowing that, plug in the fee of 6.00
6 = 300/c Multiply both sides by c.
6c = 300 Divide both sides by 6.
c = 50 cars
Answer:
f(x) = 4x+5 ; 0 ≤ x ≤ 50
The range is the possible output values of f(x)
4(0) + 5 = 5 smallest output value in range
4(50) + 5 = 55 largest output value in range
The outputs are between 5 and 55 including the endpoints so
the range is [5, 55]
