Answer:
See below
Step-by-step explanation:
Given formula
- y = x² + 3x + 2
- x- is the number of years after 2000,
- y - is the number of trout
Year 2005, finding number of trout
- x = (2005 - 2000) = 5
- y = 5² + 3*5 + 2 = 42 millions
Year 2010, finding number of trout
- x = (2010 - 2000) = 10
- y = 10² + 3*10 + 2 = 132 millions
Year 2015, finding number of trout
- x = (2015 - 2000) = 15
- y = 15² + 3*15 + 2 = 272 millions
Number of trout is trending up with significant increase over yeas
Answer:
- 42 million
- 132 million
- 272 million
- The number of trout inceases a lot each 5 years that pass.
Step-by-step explanation:
Number of trout in 2005.
Find the number of years apart from 2000 to 2005.
2005 - 2000 = 5
Substitute for x and solve for y.
y = x² + 3x + 2
y = (5)² + 3(5) + 2
y = 25 + 15 + 2
y = 40 + 2
y = 42 million
Number of trout in 2010.
Find the number of years apart from 2000 to 2010.
2010 - 2000 = 10
Substitute for x and solve for y.
y = x² + 3x + 2
y = (10)² + 3(10) + 2
y = 100 + 30 + 2
y = 130 + 2
y = 132 million
Number if trout in 2015.
Find the number of years apart from 2000 to 2015.
2015 - 2000 = 15
Substitute for x and solve for y.
y = x² + 3x + 2
y = (15)² + 3(15) + 2
y = 225 + 45 + 2
y = 270 + 2
y = 272 million
Best of Luck!
