The population density of an area is the number of people living in per unit area. The most populated region is Region A.
<h3>What is Population Density?</h3>
The population density of an area is the number of people living in per unit area. It is given by the formula,

The population density of the different regions is as follows,
Region A = 20,178 person /521 km² = 38.729 person/km²
Region B = 1,200 person /451 km² = 2.66 person/km²
Region C = 13,475person /395 km² = 34.114 person/km²
Region D = 6,980 person /426 km² = 16.385 person/km²
Hence, The most populated region is Region A.

Answer:
CB = sqrt62
Step-by-step explanation:
The pythagorean theorem will help with this! First take triangle ACD, AD^2 + CD^2 = AC^2. Plug in, AD^2 + 16 = 25. AD^2 = 9. AD = 3. I'm not exactly sure how to find DB, but I can assume it's double of AD< so 6. We know CD is 4, so 4^2 + 6^2 = CB^2. 16 + 36 = CB^2. CB = sqrt62
Sorry if this isn't exactly right, there's no exact way to find DB.

Answer:
11/5
Step-by-step explanation:
FirLet a and b be the roots of 11x^2-4x-2=0
Now
Dividing the quadratic equation by 11 we have

Now the sum of the roots is the minus of the coefficient of x and the product of the roots is the constant. Therefore

and we have
