Answer:
20 million
Step-by-step explanation:
Given : The human population doubles approximately every 50 years
To Find: If there were 2.5 million people in 1950 how many people are forecasted to populate the earth in 2100
Solution:
Equation for growth =
where a is the initial amount
y is the amount after x years
x denotes the time
A.T.Q
So, 20 million people are forecasted to populate the earth in 2100 .
Answer:
Equation of parabola:
Step-by-step explanation:
A parabola with vertex (0,0), that opens to the right.
The general equation of parabola open right whose vertex (0,0)
Focal width : Two points opposite to the the focus on parabola.
Distance between these two points is called focal width i,e 4p
Focal width = 8
So, 4p=8
p=2
Focus: (2,0)
Equation of parabola:
Answer:
Vertex: V=(0,0)=(h,k)→h=0, k=0
Opens downward:
(x-h)^2=4p(y-k)
Width focal: p=-6<0 (donwnward)
Replacing h=0, k=0 and p=-6 in the equation above:
(x-0)^2=4(-6)(y-0)
x^2=-24y
Answer: The equation of the parabola is x^2=-24y
