Answer:
Step-by-step explanation:
Given equation that shows the change in population with respect to time,
On integrating,
Put
According to the question,
If P = A if t = 0,
Thus, the required function,
If the final population = 4A,
Taking natural log both sides,
Hence, after time, the population will be quadruple its initial value.
6, 7, and 8
2x/3 + 7 <u>></u> 11
Subtract 7 from both sides
2x/3 <u>></u> 4
Multiply both sides by 3
2x <u>></u> 12
Divide both sides by 2
x <u>></u> 6
6, 7, and 8 are the ones that work
7 : 1
Paul's car goes 40 kilometers on 7 tanks.
Distance : Tanks
49 : 7
Fuel efficiency means the distance traveled by the car in one tank.
Therefore, we will reduce the ratio by dividing both sides by 7.
:
Therefore, car's fuel efficiency is 7 kilometers in one tank or the ratio between Distance traveled and fuel tanks is 7 : 1.
It means goes up by twos for example 2,4,6,8 all those numbers increase by 2s.
