Answer:
The world population will be 11.64 billions in 21 years.
Step-by-step explanation:
Initial population = 8 billion
Growth rate = 1.8% per year =0.018
Time = 21 years
We are supposed to find what will the world population be in 21 years
Formula : 
y = population after t years
r = rate of interest in decimals
t = time in years
Substitute the values :


Hence the world population will be 11.64 billions in 21 years.
Answer: c) B' = (6, -3)
<u>Step-by-step explanation:</u>
The simplest way is to rotate the graph.
Rotating the graph 1 time to the left (counterclockwise) = 90°
Rotating the graph 2 times to the left (counterclockwise) = 180°
Rotating the graph 3 times to the left (counterclockwise) = 270°
The longer way is to reflect over the x-axis and over the y-axis, which is the same as a rotation of 180°
Z = (x, y) → Z' = (-x, -y)
<em>the image below shows the graph rotated 2 times = 180°</em>

60? idk really srsly lalalalalallala
Answer:
a.48,000+2=48,002 b.30×2=60% +2=62%+48,0000=48,062
