Answer:
The populaton in year 1991 will be of 5178.9 million of people
and the population in year 2020 will be of 8524.60 million of people
Step-by-step explanation:
We measure the time t in years and let t=0 in the year 1950.
We measure the population P(t) in millions of people, then P(0)=2560 and P(10) = 3040.
Since we are assuming that dp/dt=kP, this theorem gives the following.
The relative growth rate is about 1.7% per year and the model is
<em>Year 1991 is equal in our formula to 41 and year 2020 is equal to 70. </em>Replacing,
Therefore the populaton in year 1991 will be of 5178.9 million of people and the population in year 2020 will be of 8524.60 million of people
Answer: x < 0 Interval Notation: (-∞, 0)
<u>Step-by-step explanation:</u>
This is a parabola. The left side of the parabola has a negative rate of change and the right side of the parabola has a positive rate of change.
So it will have a negative rate of change for all x-values less than the Axis of Symmetry.
h(x) = x² + 0x - 1
a=1 b=0 c=-1
It has a negative rate of change when x is less than 0
