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?
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.

(x + 3)(x + 4) = x^2 + 4x + 3x + 12 = x^2 + 7x + 12
Instead of multiplying 3 and 4 the student added them which gave them the answer of 7 when the correct answer is 12.
2)
a) x^2 + x - 2
b) x^2 - 7x + 10
c) 4x^2 - 1
d) x^2 + 10x + 25
Step-by-step explanation:
a. (x - 1)(x + 2)
x(x) - 1(x) + 2(x) - 1(2)
x^2 - 1x + 2x - 2
x^2 + x - 2

c. (2x + 1)(2x - 1)
2x(2x) + 1(2x) - 1(2x) + 1(-1)
4x^2 + 2x - 2x - 1
4x^2 - 1

Choose the correct simplification of (9xy^5)^2.
A) 18x^2y^10
B) 18x^2y^7
C) 81x^2y^7
D) 81x^2y^10
Answer:
D) 81x²y¹⁰
Step-by-step explanation:
(9xy⁵)²
Because all of 9xy⁵ are in the parentheses, each component is raised to the 2nd degree.
(9)² = 81
(x)² = x²
(y⁵)² = y¹⁰ -- When you raise an exponent to another exponent, you multiply the exponents.
Now combine the components.
D) 81x²y¹⁰

Choose all of the statements that are true about AABC.
Answer:
Step-by-step explanation:
sin(62°) = 25/BA
BA = 25/sin(62°) ≈ 28.3
Angle BAC = 180°-90°-62° = 28°
BC = √((BA)^2-(AC)^2) = 13.3
cosC = 0
Answer:
A and D are correctStep-by-step explanation:
Given ΔABC
∠C = 90°∠B = 62°AC = 25The options:
A. 25/BA = sin 62° ⇒ BA = 25/sin 62° = 28.3 ≈ 28
CorrectB. ∠BAC = 90° - 62°= 28° ≠ 48°
IncorrectC. 25/BC = tan 62° ⇒ BC = 25/tan 62° = 13.29 ≠ 18
IncorrectD. cos(∠ACB) = 0 ⇒ cos 90° = 0

Of the 600 sixth graders at Melville Middle School, 80% want more field trips. How many students want more field trips? Show your work. How many students is 10%
Answer:
480 students want more field trips.
60 students is 10%.
Step-by-step explanation:
There are 600 students, and 80% want more field trips.
80% of 600 is 0.8*600 = 8*60 = 480 students.
480 students want more field trips.
How many students is 10%?
10% of 600 is 0.1*600 = 60*1 = 60
60 students is 10%.

Step-by-step explanation:
Total world consumption of iron was approximately 900 million tons in 1993. If consumption had increased by 2.5% each year and the resources available for mining in 1993 were 450 billion tons, how much longer would the world’s iron resources have lasted?
Step-by-step explanation:
We can model the annual consumption of iron by the equation
c = 900 million tons x [tex]1.025^n[/tex], where
n is the number of years after 1993 and
c is the consumption for that year.
An estimate for the total consumption of iron can now be obtained by integrating this equation with respect to a dummy variable, x from 0 to n.
[tex]C = 900*10^6* \int\limits^n_0 {1.025^x} \, dx[/tex]
This equation simplifies to
C = 900 million tons x (1.025^n - 1) / ln(1.025), where
x is a dummy variable and
C is the total consumption of iron n years after 1993.
Let R be the amount of iron remaining at n years after 1993, so
R = 480 billion tons - C
R = 480 billion tons - 900 million tons x (1.025^n - 1) / ln(1.025)
We need to find the value of n when R is 0, so
0 = 480 billion tons - 900 million tons x (1.025^n - 1) / ln(1.025)
Simplify this equation to obtain
n = 107.4
So the iron will run out in the year 1993 + 107 = 2100
There is an ample supply of identical blocks (as shown). Each block is constructed from four 1 × 1 × 1 unit-cubes glued whole-face to whole-face. What is the greatest number of such blocks that can be packed into a box that is 6 units tall, 7 units wide, and 8 units deep without exceeding the height of the box?
Answer: 72
Step-by-step explanation: We did this question during class and this was the answer. Hope this helps!
The number of block that can be placed in box can be calculated by finding the area of the ample supply of identical blocks.
The number of block that can be placed in block is 84.
Given:
The box is 6 units tall, 7 units wide, and 8 units deep.
Calculate the area of the box.
[tex]\begin{aligned}{\rm Area\: of\:the\: box}=6\times7\times 8\\=336\:\rm units\\\end[/tex]
The four block has [tex]1\times1\times1[/tex] unit-cubes.
Calculate the area of 4 block.
[tex]\begin{aligned}{\rm Area\:of\:four\:block}&=4\times1\times1\times1\\&=4\\\end[/tex]
Now, calculate the number of block that can be placed,
[tex]\begin{aligend}{\rm Block\: placed\: in \:box}&=\dfrac {\rm Area\: of\: box}{\rm Area \:of\: Block}\\&=\dfrac{336}{4}\\&=84\\\end{aligned}[/tex]
Thus, the number of block that can be placed in block is 84.

Answer:
y = 6
Step-by-step explanation:
you cross multiply so 3 x 16 = 46 and 8 x y = 8y
it should look like this now -> 8y = 48
divide both sides by 8 -> y = 6
Answer:
y=6
Step-by-step explanation:
rewrite equation 16/y=8/3
multiply the numerator of the first fraction by the denominator of the second fraction. set this equal to the product of the denominator of the first fraction and the numerator of the second fraction
16 * 3= y * 8
rewrite equation as y*8=16*3
multiply 16 by 3
y*8=48
divide each term in y88=48 by 8
y=48/8
divide 48 by 8
y=6
