Answer:
(0, 5)
Step-by-step explanation:
This is the concept of application of exponential growth, suppose in 1990 time,t=0 and in 1990 time,t=9. Using the exponential growth formula given by:
f(t)=ae^(kt)
thus substituting the value we get:
40=37e^(9k)
this can be written as:
(40/37)=e^(9k)
introducing the natural logs we get:
ln(40/37)=9k
hence;
k=1/9ln(40/37)=0.0087
Therefore our formual will be given by:
f(t)=37e^(0.0087t)
N/B: The population is in millions. Thus to get the population in 2016 we shall proceed as follows;
t=26
thus
f(t)=37e^(26*0.0087)
f(t)=46.35 million
Answer:
a is the right answer Alexis
Step-by-step explanation:
Given:
The equation is
Where, y is the total cost and x is the number of months.
To find:
The y-intercept of the line represented by this equation.
Solution:
We have,
Isolate y variable.
Divide both sides by 0.05.
Putting x=0, we get
Therefore, the y-intercept of the given equation is 25 and the correct option is D.
