uppose p ( t ) p(t) represents the population of a certain mosquito colony, where t t is measured in days. the current population of the colony is known to be 578 578 mosquitos; that is, p ( 0 )
The size of the population of mosquito follows an exponential model.
the size of the population in 10 days is 1370
The size of the population in 10 days is 1370
The given parameters are:
p(0) = 574
p'(0)= 50
An exponential function is represented as:
p(t) =p(0) * e^ rt
So, we have:
p(t)=574*e^rt
Differentiate
p'(t)=574*r*e^rt
Substitute 0 for t
50=574 r
Divide both sides by 574
r=0.087
The function becomes
p(t)= 574*e^rt
= 574*e^0.087 t
In 10 days, t = 10.
So, we have:
p(10)=574*e^0.87
Solve
p(0)=1370
Hence, the size of the population in 10 days is 1370

Find the points on the graph of[tex]x^{2/3}[/tex] + [tex]y^{2/3}[/tex] = 1 where the tangent line has slope 1
Any point satisfying the relation y = -[1 - (∛x²)]²(1/(∛x)) will be points on the graph where the tangent line has slope 1.
What is the slope of a given line?
A line's slope in mathematics is defined as the ratio of the change in the y coordinate to the change in the x coordinate. Both the net change in the y-coordinate and the net change in the x-coordinate are denoted by y and x, respectively.
Consequently, the formula for the change in y-coordinate with respect to the change in x-coordinate is the slope of a line is represented by the expression m = change in y/change in x =Δy/Δx.
Additionally, the slope of the line can be shown as tan θ = Δy/Δx
So, the slope of a line is tan θ.
The given equation is: (∛x²) + (∛y²) = 1
Therefore, (∛y²) = 1 - (∛x²) ⇒ y² = [1 - (∛x²)]³
Differentiating the equation formed with respect to x, we get
2y(dy/dx) = 3[1 - (∛x²)]²(-2/3)(1/(∛x)) ⇒ dy/dx = (-1/y)[1 - (∛x²)]²(1/(∛x)) -(i)
Given, the slope of the tangent line is = 1 -(ii)
Thus, equating (i) and (ii), we get,
(-1/y)[1 - (∛x²)]²(1/(∛x)) = 1 ⇒ y = -[1 - (∛x²)]²(1/(∛x))
Therefore any point satisfying the relation y = -[1 - (∛x²)]²(1/(∛x)) will be points on the graph where the tangent line has slope 1.

JP Computers produces both laptop
and desktop computers. Laptop
computers take up 2 cubic feet of
space and desktop computers take up
5 cubic feet of space. The maximum
capacity on the delivery truck is 800
cubic feet. Due to demand, they need
to load at least 300 laptop computers.
They profit $225 on each laptop and
$280 on each desktop computer. How
many of each should they load on the
truck to maximize profit?
The load each should get to maximize the profit is $67,500, $78,700 and $90,000
What Is Profit?
In accounting, a profit is an income that is given to the owner throughout a successful market producing process. Profitability, which is the owner's primary interest in the income-formation process of market production, is measured by profit. There are various profit metrics that are frequently used.
Let x represent the total number of laptops and y represent the total number of desktop computers.
A laptop computer occupies 2 cubic feet, hence x laptops each use 2x cubic feet. Desktop computers take up 5 cubic feet of space, hence 5y cubic feet of room is required for 5y desktop computers.
They require 2x + 5y cubic feet in total.
Since the delivery truck's maximum capacity is 800 cubic feet,
2x + 5y <= 800.
They must load at least 300 laptops because of the demand,
hence, x >= 300
They make $225 on each laptop, which translates to $225 times as many computers. They make a profit of $280 on each desktop computer, or $280y on y desktops.
Total profit is:
P=$(225x + 280y)
Draw the inequality system (see attached diagram)
2x + 5y <= 800.
x >= 300
One of the common region's three vertices will have the most profit:
P(300,0) = 225(300) + 280(0) = $67,500
P(300,40) = 225(300) + 280(40) = $78,700
P(400,0) = 225(400) + 280(0) = $90,000
Hence, each should load $67,500, $78,700 and $90,000 on the truck to maximize profit

The height of the bird is given by the following equation
h(t)= -0.25t2 + 1.9t + 17

The length of a bacterial cell is about 4 x 10−6 m, and the length of an amoeba cell is about 2.5 x 10−4 m. How many times smaller is the bacterial cell than the amoeba cell? Write the final answer in scientific notation with the correct number of significant digits. A 6.25 x 10^2
B 2 x 10^2
C 6 x 10^1
D 16 x 10^1
The bacterial cell is 6.25 x 10 times smaller than the amoeba cell.
The length of the Bacterial cell is 4 x 10⁻⁶ meters.
The length of the Amoeba cell is 2.5 x 10⁻⁴ meters.
The length L of the bacterial cell can be written as,
L = 0.000004 meters.
Also, the length L' of the amoeba cell can be written as,
L' = 0.00025 meters.
Let us say that the bacterial cell is N times smaller than the amoeba cell.
So. we can write,
Length of bacterial cell x N = length of amoeba cell.
LN = L'
0.000004(N) = 0.00025
N = 0.00025/0.000004
N = 62.5
So, now we can say that the length of the bacterial cell is 62.5 times smaller than he amoeba cell.
As we have to state our answer in scientific notation,
We can write 62.5 as 6.25 x 10.

Pythagoras's theorem - The two teachers are both seated at a distance of 15 meters from each other.
What is Pythagoras' theorem?
The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic Euclidean geometry relationship between a right triangle's three sides. According to this rule, the area of the square with the hypotenuse (the side across from the right angle) is equal to the sum of the areas of the squares with the other two sides. The Pythagorean equation, which generally refers to the relationship between the lengths of the legs a, b, and the hypotenuse c, can be used to represent this theorem.
We are given,
the distance between Krysta and her math teacher to be 12 meters, and the distance between Krysta and her science teacher to be 9 meters
for simplicity, we'll let
the distance between Krysta and her math teacher to be KM =12 meters

The graph of the linear inequality can be seen in the image at the end.
How to identify the graph of the inequality?
Here we have the linear inequality:
y ≥ 2x + 1
To graph this, we first need to graph the line.
y = 2x + 1
With a solid line, because we have the symbol ≥, which means that the points on the line are solutions.
Once we graphed that line, we look at our inequality:
y ≥ 2x + 1
It says that y is larger than or equal to the values on the line, so once the line is graphed we need to shade all the region above that line.

Answer:
$400

We see that the discount price is (100-40) = 60% of the original price
If 60% corresponds to $240, than 10% corresponds to 240/6 = $40
Since the original price is 100% = 10*10%, the original price is 10* $40 = 400.

a gardener has 760 feet of fencing to fence in a rectangular garden. one side of the garden is bordered by a river and so it does not need any fencing.
The dimensions that would guarantee that the garden has the greatest possible area is 190 feet on the shorter side and 380 feet on the longer side to produce an area of 72,200 square feet.
A dimensions of a rectangle is the length of each side.
Let x = length of the shorter side
y = length of the longer side
If one side of the garden is bordered by a river and so it does not need any fencing, and assume that the longer side is this side, then the perimeter that only needs to be fenced by 760 feet of fencing materials is
2x + y = 760
y = 760 - 2x
The area of the rectangular garden is the product of the shorter side and the longer side of the garden. Hence,
A = xy
A = x(760 - 2x)
A = 760x - 2x²
To obtain the largest area possible, the first derivative of the area should be equal to zero.
A(x) = 760x - 2x²
A'(x) = 0
760 - 4x = 0
Solve for x.
760 - 4x = 0
4x = 760
x = 190
length of the shorter side = 190 feet
y = 760 - 2x
y = 760 - 2(190)
y = 380
length of the longer side = 380 feet
Solve for the greatest possible area.
A = xy
A = 190 feet(380 feet)
A = 72,200 square feet
