Answer:
1. y = (3x^2 - 4)
2. y = (-x^2) + 2
3. y = (-x^2 - 8)
4. y = (3x^2 - 2) + 4
5. y = (3x^2 + 4)
6. y = (-1/4x^2)
Step-by-step explanation:
To solve this problem, let us first assign some variables.
Let us say that:
d = represents the population density of the circular region
(in units of 513 people per square mile)
p = represents the population of the circular region (in
units of people)
r = is the radius of the circular region
Now we can see that if we divide p by d, we can get a value
which has a units of square mile. Thus the area of the region, hence:
Area = 79,000 people / (513 people per square mile)
Area = 154 square mile
The area of a circle has the formula:
Area = π r^2
Therefore calculating for r:
154 square mile = π r^2
r = 7 miles (ANSWER)
After simplifying The answer is -8/3
Answer:
33.33%
Step-by-step explanation:
The line of best fit for the data is represented by the equation y = 3x + 15.
At x = 4,
y = 3(4) + 15 = 27
At x = 7,
y = 3(7) + 15 = 36
We need to find the percent change in the total number of trees from x = 4 to x = 7.
So,

So, the required percentage change is equal to 33.33%.
