A population of 2000 fish increases at an annual rate of 7.5%. Write the model, then predict how
many fish will there be in 10 years?
Answers
Answer:
The model is [tex]P(t) = 2000(1.075)^{t}[/tex].
There will be 4122 fish in 10 years.
Step-by-step explanation:
Exponentially increasing population:
An exponentially increasing population can be represented by the following model:
[tex]P(t) = P(0)(1+r)^t[/tex]
In which P(t) is the population after t years, P(0) is the initial population, and r is the growth rate, as a decimal.
A population of 2000 fish increases at an annual rate of 7.5%.
This means that [tex]P(0) = 2000, r = 0.075[/tex]
So
[tex]P(t) = P(0)(1+r)^t[/tex]
[tex]P(t) = 2000(1+0.075)^t[/tex]
[tex]P(t) = 2000(1.075)^{t}[/tex]
This is the model.
How many fish will there be in 10 years?
This is P(10).
[tex]P(t) = 2000(1.075)^{t}[/tex]
[tex]P(10) = 2000(1.075)^{10} = 4122[/tex]
There will be 4122 fish in 10 years.
Angie has already written 19 pages, and she expects to write 1 page for every additional
hour spent writing. How many hours will Angie have to spend writing this week in order to
have written a total of 28 pages?
Answers
Answer:
[tex]9[/tex]
Step-by-step explanation:
[tex]28 - 19 = 9[/tex]
9 hours
Explanation:
What we know:
- Angie has already written 19 pages
- Angies writes 1 page per hour
First, we can create the following equation to model this scenario:
Let x be equal to the number of hours that pass.
Total number of pages=1x+19
Now, because Angie wants to write 28 pages in total, we can plug that into the left side of the equation and solve for x, the number of hours.
28=1x+19
Subtract both sides by 19
28-19=1x+19-19
9=1x
x=9
Therefore, Angie would have to spend 9 hours to write a total of 28 pages.
I hope this helps!

Answer:-43 + 9x = 0
Step-by-step explanation:Simplifying
9x + -43 = 0
Reorder the terms:
-43 + 9x = 0
Solving
-43 + 9x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '43' to each side of the equation.
-43 + 43 + 9x = 0 + 43
Combine like terms: -43 + 43 = 0
0 + 9x = 0 + 43
9x = 0 + 43
Combine like terms: 0 + 43 = 43
9x = 43
Divide each side by '9'.
x = 4.777777778
Simplifying
x = 4.777777778

Which point on the coordinate plane below is (-9, 3)?
Point D
Point C
Point B
Point A
Answers
Answer:B
Step-by-step explanation: x is -9 and y is 3
Since it’s negative you’d go left by 9 blocks and the y is positive so you go up 3
Answer:
The answer is point B
Step-by-step explanation:
I know this because (-9, 3) seems to be located in quadrant 2 because in quadrant 2 along the x-axis it is negative and along the y-axis it is positive. So, when l look in quadrant 2 there seems to be only one point, point B, which if you look at it is 9 units to the left and 3 units upward.
