Answer:
7,228,202%
Step-by-step explanation:
Population at first census in 1979 was 3929
If the Population had increased to 284,000,000 by 2000, the population increase will be;
284,000,000-3929
= 283,996,071
%increase in population = increment/initial population×100%
= 283,996,071/3929×100%
= 7,228,202%
This means that the population has increased by 7,228,202%

Step-by-step explanation:
Answer:
-20.5
Step-by-step explanation:
Using a basic calculator, you divide 10.25 by -.5 which easily gives -20.5
Answer:
A)
Step-by-step explanation:
the solution of a squared equation is
x = (-b ± sqrt(b² - 4ac)) / (2a)
in our case
a = 1
b = 8
c = 22
x = (-8 ± sqrt(64 - 88))/2 = (-8 ± sqrt(-24))/2 =
= (-8 ± sqrt(4×-6))/2 = (-8 ± 2×sqrt(-6))/2 =
= -4 ± sqrt(-6) = -4 ± i×sqrt(6)
Answer:
slope that is undefined
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = A(- 3, 5) and (x₂, y₂ ) = B(- 3, 3)
m =
= 
Division by zero is undefined
Thus the slope of AB is undefined
