eight less than
3n-8
Answer:
The graph in the attached figure
Step-by-step explanation:
we have
Remember that the radicand must be greater than or equal to zero
so
solve for x
subtract 2 both sides
The domain is the interval [-2,∞)
All real number greater than or equal to -2
For x=-2
so
The range is the interval [0,∞)
All real number greater than or equal to 0
Find the y-intercept
Remember that the y-intercept is the value of y when the value of x is equal to zero
For x=0
The y-intercept is the point (0,4.243)
therefore
The graph in the attached figure
Answer:
Approximately 107years
Step-by-step explanation:
Given the population of Mathloversville modelled by the equation P=38e^0.095t where t is the number of years from now.
To find the time it will take the population to reach 1million from now, we will substitute P = 1,000,000 into the equation given
1,000,000 = 38e^0.095t
Dividing both sides by 38
1,000,000/38 = e^0.095t
Taking the ln of both sides
ln(1,000,000/38) = ln e^0.095t
ln26,315.79 = 0.095t
10.18 = 0.095t
t = 10.18/0.095
t = 107.16years
It will take approximately 107years for the population to reach 1million
