Answer:

[tex]P(t) = (2t + 50)^2[/tex]

Step-by-step explanation:

A certain population increases at a rate proportional to the square root of the population.

This means that the population can be described by the following differential equation:

[tex]\frac{dP}{dt} = r\sqrt{P}[/tex]

In which r is the growth rate.

Solving by separation of variables, we have that:

[tex]\frac{dP}{\sqrt{P}} = r dt[/tex]

Integrating both sides:

[tex]2\sqrt{P} = rt + K[/tex]

In which K is a random constant

[tex]\sqrt{P} = 0.5rt + K[/tex]

Finding the squares of both sides:

[tex]P(t) = (0.5rt + K)^2[/tex]

Finding the value of K

The initial population is of 2500. That is, when [tex]t = 0, P = 2500[/tex]. So

[tex]P(t) = (0.5rt + K)^2[/tex]

[tex]2500 = (0.5r(0) + K)^2[/tex]

[tex]K^2 = 2500[/tex]

[tex]K = \sqrt{2500}[/tex]

[tex]K = 50[/tex]

So

[tex]P(t) = (0.5rt + 50)^2[/tex]

Finding the value of r

Population of 3600 in 5 years(when t = 5). So

[tex]P(t) = (0.5rt + 50)^2[/tex]

[tex]3600 = (0.5r(5) + 50)^2[/tex]

[tex](2.5r + 50)^2 = 3600[/tex]

Taking the square root of both sides

[tex]\sqrt{(2.5r + 50)^2} = \sqrt{3600}[/tex]

[tex]2.5r + 50 = 60[/tex]

[tex]2.5r = 10[/tex]

[tex]r = 4[/tex]

So, the equation for the population at the end of t years is given by:

[tex]P(t) = (0.5rt + 50)^2[/tex]

[tex]P(t) = (0.5(4)t + 50)^2[/tex]

[tex]P(t) = (2t + 50)^2[/tex]

Area of the given figure is 199.5 square miles.

Area of a two dimensional shape is the total region which is bounded by the object's shape.

The given figure can be divide in to smaller figures to find the area of each smaller figure and add it.

A rectangle with sides 5 miles and 3 miles.

A rectangle with sides 15 miles and 6 miles.

A rectangle with sides (8 - 5) + 6 = 9 miles and 3 miles.

A triangle with base length 9 miles and height 8 + 6 + 3 = 17 miles.

Area = (5 × 3) + (15 × 6) + (9 × 3) + (1/2 × 9 × 17)

        = 15 + 90 + 18 + 76.5

        = 199.5 square miles

Hence the area of the given figure is 199.5 square miles.

A percentage is a way to describe a part of a whole. The correct option is B.

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

Given that the colony of 100,000 ants has been declining in number at a rate of 11.4% per month. Therefore, the number of months it will take for the ant population to reach 25,000 ants is,

Population = 100,000(1-0.114)ⁿ

25,000 = 100,000(1-0.114)ⁿ

0.25 = 0.886ⁿ

log(0.25) / log(0.886) = n

n = 11.45335

Since the value is close to 12.2 months.

Hence, the correct option is B.

Answer:

Dan is recycling equal weight of printers and monitors.

Step-by-step explanation:

Let,

x be the number of printers

y be the number of monitors

According to given statement;

x+y=60      Eqn 1

25x+35y=1750   Eqn 2

Multiplying Eqn 1 by 25

25(x+y=60)

25x+25y=1500    Eqn 3

Subtracting Eqn 3 from Eqn 2

(25x+35y)-(25x+25y)=1750-1500

25x+35y-25x-25y=250

10y = 250

Dividing both sides by 10

[tex]\frac{10y}{10}=\frac{250}{10}\\y=25[/tex]

Putting y=25 in Eqn 1

x+25=60

x=60-25

x=35

Weight of printers = 35*25 = 875 lb

Weight of monitors = 25*35 = 875 lb

Therefore,

Dan is recycling equal weight of printers and monitors.

Answer:

y = -2x + 2

Step-by-step explanation:

Plug in the point and slope into y = mx + b, and solve for b:

y = mx + b

-2 = -2(2)  + b

-2 = -4 + b

2 = b

Plug in the slope and y intercept into y = mx + b

y = -2x + 2

So, the equation is y = -2x + 2

Answer:

Mean = 60

Median = 56

Mode = 48

Range = 32

Step-by-step explanation: You can find the Mean by adding all the number together then dividing by how many number in the problem. So, 48 + 64 + 80 + 48 = 240 then, divide by 4, which is how many numbers are in this equation.  You can find the Median by putting the numbers in the equation in order, 48, 48, 64, 80. Then, you will find what number is in the middle, or look at it as for the number in the middle to have the same amount of numbers on each side. So, in this case 48 and 64 are in the middle. There are two numbers in the middle instead of one, so you have to add them together to get 112 then divide by 2, because it is how many numbers you added together. You can find the Mode by seeing what number occurs the most, which in this case is 48, it appears two times. Sometimes, there will be no mode. You can find the Range by putting the numbers in order and subtracting the highest amount from the lowest amount, which in this case is 80 - 48 = 32. Hope this helps ^-^
