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.
Answer:
f(x) = (x + 11) (x + 3) (x − 1) (x − 3)
Step-by-step explanation:
f(x) = x⁴ + 10x³ − 20x² − 90x + 99
f(x) is a fourth order polynomial, so it has 4 roots. Use rational root theorem to find possible rational roots.
±99, ±11, ±9, ±3, ±1
By trial and error, the zeros are -11, -3, 1, and 3.
f(x) = (x + 11) (x + 3) (x − 1) (x − 3)
Answer:
Proved: AC = BD
Step-by-step explanation:
The complete question related to this with diagram can be found at toppr website.
Given: O is the mid point of AB and CD
Find attached the diagram
∠COA = ∠BOD (vertical angles are equal)
∠AOD = ∠COB (vertical angles are equal)
For ∆AOC
AC + OC + OA = 180° (sum of angles in a triangle)
For ∆DOB
DB + OB + OD = 180° (sum of angles in a triangle)
OC = OD (sides are equal)
OA = OB (sides are equal)
Since both ∆AOC and ∆DOB are equal to 180°, AC = DB.
DB = BD
Proved: AC = BD
