The fish population in a local stream is decreasing at a rate of 3% per year. The original population was 48,000. Write an expon
ential function to model this situation. Then find the population after 7 years.
1 answer:
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Decrease rate (d)= 7%
Number of periods (n)= 7 years
Current population (PV)= 48,000
<u>First, to calculate the future value, we need to use the following decrease exponential formula:</u>
<u />
FV= PV*[(1+d)^-n]
<u>After 7 years:</u>
FV= 48,000*(1.07^-7)
FV= 29,892

{h| 0 ≤ h ≤ 60}
Step-by-step explanation:
Next time, please separate the possible answer choices with commas or semi-colons, or put them on separate lines.
The second set says it all: {h| 0 ≤ h ≤ 60}. This guy cannot work more than 60 hours per week, and h cannot be negative.
The first one : -6
the second : -14
X = -2/7
5x = 1/2 ( 3x - 2 )
5x = 1.5x - 1
3.5x = -1
x = -2/7
Answer:
(22,2) and (18,6)
Step-by-step explanation:
Heyyyy so the equation is y=24-x
So let's do 24-x to get y
24-18=6
Same thing
24-22=2
I also did this on Khan so yeah its right :D
