8.5X60 = 510 feet/min
510X60 = 30,600 feet/hour
It's the second one.
since the graph is exponential, it grows faster.
After all for example: 3 squared is different than saying 3×2. That's the whole reasoning behind this question
Answer:
Population density = 1569 persons per mile.
Step-by-step explanation:
Population density is a measure of how crowded or uncrowded a specific piece of land in a geographical location or country is.
Given the following data;
Total population, N = 56,474 people
Area, A = 36 mi
To find the population density;
Population density = N/A
Population density = 56474/36
Population density = 1568.72 ≈ 1569 persons per mile.
Therefore, the population density of Valdosta is 1569 persons per mile.
Answer:
No
Step-by-step explanation:
In different scenarios, the data will be different. However, sometimes, it's impossible to draw a histogram with equal widths, so in order to maintain clarity and fairness, the area of the bars should actually be proportional to the frequency, which is usually the y-axis of the graph or height of the bars.
Hope this helps!
Answer:
x² + 6x + 9
Explanation:
![\sf = \left(x+3\right)^2](https://tex.z-dn.net/?f=%5Csf%20%3D%20%5Cleft%28x%2B3%5Cright%29%5E2)
Use perfect square formula: (a + b)² = a² + 2ab + b²
![= \sf x^2 + 2(x) (3) + 3^2](https://tex.z-dn.net/?f=%3D%20%5Csf%20x%5E2%20%2B%202%28x%29%20%283%29%20%20%2B%203%5E2)
simplify the following
![= \sf x^2 + 6x +9](https://tex.z-dn.net/?f=%3D%20%5Csf%20x%5E2%20%2B%206x%20%20%2B9)
Hence Maria is not correct. The correct answer is x² + 6x + 9.
