you will build a rectangular sheep pen next to a river. there is no need to build a fence along the river, so you only need to build three sides. you have a total of 460 feet of fence to use, and the area of the pen must be 26000 square feet. find the dimensions of the pen.
We find that the dimensions of the rectangular sheep pen are L = 100 feet and W = 260 feet.To find the dimensions of the rectangular sheep pen, we need to solve for the length and width of the pen.
Let's assume the length of the pen is L and the width is W.
We know that the area of a rectangle is calculated by multiplying the length and width: Area = Length * Width.
Given that the area of the pen must be 26000 square feet, we have the equation L * W = 26000.
We also know that we only need to build three sides of the pen, so the total length of the fence used will be the sum of the three sides: L + W + L = 2L + W.
Given that we have a total of 460 feet of fence to use, we have the equation 2L + W = 460.
Now we have a system of two equations with two variables. We can solve this system to find the values of L and W.
Using these two equations:
L * W = 26000
2L + W = 460
We can substitute the value of W from the second equation into the first equation:
L * (460 - 2L) = 26000.
By simplifying and rearranging, we get:
-2\(L^2\)+ 460L - 26000 = 0.
This equation can be solved by factoring or using the quadratic formula. After solving, we find that the dimensions of the rectangular sheep pen are L = 100 feet and W = 260 feet.

Select the best answer regarding the effects of Carbon monoxide: a. The affinity between CO and hemoglobin is about the same as oxygen. b. The central chemoreceptors will detect the reduction in oxygen delivered to the cells and will increase their firing rate. c. CO results in less oxygen loading hemoglobin but unloading is not changed. d. A small amount of CO in the air will not reduce arterial PO2 levels enough to be sensed by the peripheral chemoreceptors.
The best answer regarding the effects of carbon monoxide is option c, CO results in less oxygen loading hemoglobin but unloading is not changed.
Carbon monoxide binds up more tightly to the hemoglobin as compared to the oxygen molecules. This reduces the oxygen-carrying capacity of the blood and results in less oxygen loading onto hemoglobin.
However, once oxygen is already bound to hemoglobin, CO does not significantly affect its release or unloading. Therefore, option c is the most accurate statement among the given choices.

Answer:
B. The function shown on the graph has a smaller rate of change but a higher starting point
Step-by-step explanation:
Question options obtained from a similar question are;
A. The function shown on the graph has a greater rate of change and a higher starting point
B. The function shown on the graph has a smaller rate of change but a higher starting point
C. The function shown on the graph has a greater rate of change but a lower starting point
The function shown on the graph has a smaller rate of change but a higher starting point
Explanation;
The given function with which the graph is compared is y = 4·x + 2
From the given function, we have;
The rate of change of the function is the coefficient of 'x', therefore, the rate of change of the function = 4
When y = 0, 4·x + 2 = 0,
∴ x = -2/4 = -0.5
The y-intercept is given when x = 0
∴ The y-intercept, y = 4 × 0 + 2 = 2
The starting point of the function, is (0, 2)
From the graph, we have;
The y-intercept = (0, 4)
Therefore, the starting point of the line, the y-intercept, (0, 4), is higher than the starting point of the given function, (0, 2)
The coordinates of two (clear) points on the line in the graph are (0, 4) and (-2, -2)
The rate of change of the line, m = (4 - (-2))/(0 - (-2)) = 3
Therefore, the graph has a lesser rate of change, 3, than the rate of change of the given function, 4
When compared with the given function, 'the function shown on the graph has a smaller rate of change and a higher starting point'.

The Routh-Hurwitz stability criterion is a technique for deciding the stability of linear time-invariant systems.
The Routh-Hurwitz criteria are a collection of necessary and sufficient conditions for the stability of a polynomial whose coefficients are real numbers.
It can be used to calculate the location of the roots of a polynomial's characteristic equation. Below are the solutions to the given polynomial equations:
Solution 1: Using Routh-Hurwitz criterion for s⁵ + 3s⁴ + 9s³ + 8s² + 65 + 4= 0:
Routh table is given below: s⁵ = 1 3 4 0 0
s⁴ = 3 8 65 0
s³ = 2.36 16.6 0
s² = 8.9 65 0
s¹ = 68 0
s⁰ = 4
There are three poles in the right half plane (RHP) of the complex plane for the given equation.
Hence, the system is unstable.
Solution 2: Using Routh-Hurwitz criterion for s⁵ + 6s³ + 5s² + 8s + 20=0:
Routh table is given below:
s⁵ = 1 5
s⁴ = 6 8
s³ = 2 20
s² = 4 -20
s¹ = -10
s⁰ = 20
There are no poles in the RHP of the complex plane for the given equation.
Therefore, the system is stable.
Hence, the answer is:1.1
Note: When the roots of the characteristic equation are located on the imaginary axis, the Routh-Hurwitz criteria fail.
A little change in the equation coefficients leads to no information on stability.
Hence, we cannot conclude the stability of the system.

a skscraper casts a shadow 200 feet long. if the angle of elevation of the sun is 38, then the height of the skyscraper is approximently .
The height of the skyscraper is approximately 156.25 feet
First of all, let's recall some trigonometric functions that are used in the given problem:
tanθ = Perpendicular/Base
or tan θ = Opposite/Adjacent
where θ is the angle of elevation.
We have given the length of the shadow, which is the base.
We have to determine the height of the skyscraper, which is the perpendicular.
We can calculate the angle of elevation using the following formula:
θ = tan⁻¹(opposite/adjacent)
Here, opposite is the height of the skyscraper, and adjacent is the length of the shadow.
We can calculate the value of θ as:θ = tan⁻¹(h/200) .... (1)
According to the problem, θ = 38.
We can substitute the value of θ in equation (1) and find the value of h:
h = 200 tan(38°)h
= 200 × 0.78125h
= 156.25 feet.
We can check our answer using the Pythagorean theorem:
Height² + Base² = Hypotenuse²h² + 200²
= (200/tan(38°))²h² + 40000
= 29554.45²h²
= 29554.45² - 40000h²
≈ 24589.59h

What is area of rectangle ?
Area of rectangle is the region occupied by a rectangle within its four sides or boundaries.
It is given that the floor has an area of x² + 6x + 8.
We know that area of rectangle is given by :
A = Length × Width
Let's simplify the expression x² + 6x + 8.
x² + 6x + 8
= x² + 4x + 2x + 8
= x (x + 4) + 2(x + 4)
or
x² + 6x + 8 = (x + 2) (x + 4)
Let's compare this with the formula for area of rectangle , which is A = L × B. So , we get :
Length = (x + 2)
Width = (x + 4)
We know that the perimeter of a rectangle is given by formula :
P = 2 (L + B)
or
P = 2(x + 2 + x + 4)
P = 2( 2x + 6)
P = 4x + 12
Therefore , the perimeter of the floor will be equal to 4x + 12.

Given the tangent line to the graph of y=h(x) at the point (-1,4) passes through (3,6), to get h(-1) and h'(-1), we should calculate the following:
Gradient of the tangent line:
Gradient=change in y axis/change in x axis=Δy/Δx

Gradient=(6-4)/(3--1)
=2/4

Gradient=1/2 or 0.5
Equation of the tangent line:
This should be in the form of y=mx+c, where m is the gradient of the line
We use the gradient and one of the x and y coordinates get the equation of the tangent line
Gradient=change in y axis/change in x axis=Δy/Δx, and gradient was found as 1/2
Δy/Δx=1/2
(y-4)/(x--1)=1/2
(y-4)/(x+1)=1/2
2y-8=x+1
y=(1/2)x+4.5
Equation of the tangent line is y=(1/2)x+4.5 or y=0.5x+4.5

Use the given information to find the unknown value. y varies directly as the square of x. When x=4, then y=96. Find y when x=5.
Y varies directly as the square of x with a constant of variation k = 6. When x = 5, y = 150.
Using the given information that y varies directly as the square of x, we can find the unknown value of y when x = 5. When x = 4, y = 96.
When a variable y varies directly as the square of another variable x, we can express this relationship as y = kx^2, where k is the constant of variation.
To find the value of k, we can substitute the values of x and y when x = 4 and y = 96 into the equation. Thus, we have 96 = k * 4^2, which simplifies to 96 = 16k. Solving for k, we divide both sides by 16, yielding k = 6.
Now that we know k, we can find the value of y when x = 5. Substituting x = 5 and k = 6 into the equation y = kx^2, we have y = 6 * 5^2, which simplifies to y = 6 * 25 = 150.
Therefore, when x = 5, y = 150 based on the given information.
