F=5x
f-1x=5x-1x=4x
so f-1x=4x
Hey there! :)
Answer:
The first option:
Y-intercept: 9
Zeros: 1, -1, 3, -3
Step-by-step explanation:
The Y-intercept is where the graph intersects with the y-axis. On this graph, we can see that the graph intersects at y = 9.
The zeros of the graph are where the graph intersects the x-axis. When looking at the graph, the x-axis is intersected at x = -3, x = -1, x = 1, and x = 3.
Therefore, A, or the first option, is the correct answer.
The population density is 73.54 people per square kilometer
<em><u>Solution:</u></em>
Given that,
Area of europe =
square kilometers
Population = ![7.31 \times 10^8](https://tex.z-dn.net/?f=7.31%20%5Ctimes%2010%5E8)
<em><u>To find: population density</u></em>
<em><u>The formula for population density is given as:</u></em>
![\text{ population density } = \frac{\text{ number of people }}{\text{ land area }}](https://tex.z-dn.net/?f=%5Ctext%7B%20population%20density%20%7D%20%3D%20%5Cfrac%7B%5Ctext%7B%20number%20of%20people%20%7D%7D%7B%5Ctext%7B%20land%20area%20%7D%7D)
<em><u>Substituting the values in formula, we get</u></em>
![\text{Population density } = \frac{7.31 \times 10^8}{9.94 \times 10^6}\\\\\text{ use the law of exponent } \frac{a^m}{a^n} = a^{m-n}\\\\\text{Population density } = 0.7354 \times 10^{8-6}\\\\\text{Population density } = 0.7354 \times 10^2\\\\\text{Population density } = 73.541](https://tex.z-dn.net/?f=%5Ctext%7BPopulation%20density%20%7D%20%3D%20%5Cfrac%7B7.31%20%5Ctimes%2010%5E8%7D%7B9.94%20%5Ctimes%2010%5E6%7D%5C%5C%5C%5C%5Ctext%7B%20use%20the%20law%20of%20exponent%20%7D%20%5Cfrac%7Ba%5Em%7D%7Ba%5En%7D%20%3D%20a%5E%7Bm-n%7D%5C%5C%5C%5C%5Ctext%7BPopulation%20density%20%7D%20%3D%200.7354%20%5Ctimes%2010%5E%7B8-6%7D%5C%5C%5C%5C%5Ctext%7BPopulation%20density%20%7D%20%3D%200.7354%20%5Ctimes%2010%5E2%5C%5C%5C%5C%5Ctext%7BPopulation%20density%20%7D%20%3D%2073.541)
On rounding to nearest hundreth (two decimal places ), we get 73.54
Thus the population density is 73.54 people per square kilometer
