A company has a manufacturing plant that is producing quality jackets. They find that in order to produce 150 jackets in a month, it will cost $5500. Also , to produce 370 jackets in a month , it will cost $8580 . Find an equation in the form y = mx + b , where is the number of jackets produced in a month and y is the monthly cost to do so.
Answer:
\(y = 14x + 3400\)
Step-by-step explanation:
Represent
- number of jackets with x
- costs of jackets with y
So, we have:
\((x_1,y_1) = (150,5500)\)
\((x_2,y_2) = (370,8580)\)
Required
Write an equation in form of y = mx + b
First, we need to determine the slope (m)
\(m = \frac{y_2 - y_1}{x_2 - x_1}\)
\(m = \frac{8580 - 5500}{370 - 150}\)
\(m = \frac{3080}{220}\)
\(m = 14\\\)
The equation is calculated using:
\(y-y_1 = m(x - x_1)\)
Where
\(m = 14\\\)
\((x_1,y_1) = (150,5500)\)
So, we have:
\(y - 5500 = 14(x - 150)\)
\(y - 5500 = 14x - 2100\)
Make y the subject
\(y = 14x - 2100 + 5500\)
\(y = 14x + 3400\)

A box has a width of 10 cm and a length of 17 cm. The volume of the box is decreasing at a rate of 527 cubic cm per minute, with the width and length being held constant. What is the rate of change, in cm per minute, of the height when the height is 6 cm?
Round your answer to the nearest hundredth. (Do not include any units in your answer.)
Therefore, the rate of change, in cm per minute, of the height when the height is 6 cm is approximately -6 cm/min.
Given,The width of the box = 10 cm Length of the box = 17 cmThe volume of the box = 527 cubic cm/minWe need to find the rate of change, in cm per minute, of the height when the height is 6 cm.We know that the volume of the box is given as:V = l × w × h where, l, w and h are length, width, and height of the box respectively.It is given that the width and length are being held constant.
Therefore, we can write the volume of the box as
:V = constant × h Differentiating both sides with respect to time t, we get:dV/dt = constant × dh/dtNow, it is given that the volume of the box is decreasing at a rate of 527 cubic cm per minute.
Therefore, dV/dt = -527.Substituting the given values in the above equation, we get:
527 = constant × dh/dt
We need to find dh/dt when h = 6 cm.To find constant, we can use the given values of length, width and height.Substituting these values in the formula for the volume of the box, we get:
V = l × w × hV = 17 × 10 × hV = 170h
We know that the volume of the box is given as:V = constant × hSubstituting the value of V and h, we get:
527 = constant × 6 cm
constant = 87.83 cm/minSubstituting the values of constant and h in the equation, we get
-527 = 87.83 × dh/dtdh/dt = -6.0029 ≈ -6 cm/min

∫ (log(1 + x ^ 2))/((x + 1) ^ 2) dx
The final result of the integral is:
∫ (log(1 + x²) / (x + 1)²) dx = log(x + 1) - 2 (log(x + 1) / x) - 2Li(x) + C,
where Li(x) is the logarithmic integral function and C is the constant of integration.
We have,
To solve the integral ∫ (log(1 + x²) / (x + 1)²) dx, we can use the method of substitution.
Let's substitute u = x + 1, which implies du = dx. Making this substitution, the integral becomes:
∫ (log(1 + (u-1)²) / u²) du.
Expanding the numerator, we have:
∫ (log(1 + u² - 2u + 1) / u²) du
= ∫ (log(u² - 2u + 2) / u²) du.
Now, let's split the logarithm using the properties of logarithms:
∫ (log(u² - 2u + 2) - log(u²)) / u² du
= ∫ (log(u² - 2u + 2) / u²) du - ∫ (log(u²) / u²) du.
We can simplify the second integral:
∫ (log(u²) / u²) du = ∫ (2 log(u) / u²) du.
Using the power rule for integration, we can integrate both terms:
∫ (log(u² - 2u + 2) / u²) du = log(u² - 2u + 2) / u - 2 ∫ (log(u) / u³) du.
Now, let's focus on the second integral:
∫ (log(u) / u³) du.
This integral does not have a simple closed-form solution in terms of elementary functions.
It can be expressed in terms of a special function called the logarithmic integral, denoted as Li(x).
Therefore,
The final result of the integral is:
∫ (log(1 + x²) / (x + 1)²) dx = log(x + 1) - 2 (log(x + 1) / x) - 2Li(x) + C,
where Li(x) is the logarithmic integral function and C is the constant of integration.

Answer:
The values of x for the inequality |x +9| ≥ −6 are x = -3, -15.
Step-by-step explanation:
An equation of inequality is given that is |x +9| ≥ −6 that is to be solved for x.
Firstly let us understand what is an inequality;
In mathematics, inequalities specify the connection between two non-equal numbers. To be unequal is to be unequal.
Now, let us consider the given inequality;
=> |x +9| ≥ −6
Let us take this equation this way to solve which is the negative value of terms of the bar;
=> -(x + 9) = −6
=> -x = -6 + 9
=> x = -3
Now, Let us take this equation this way to solve which is the positive value of terms of the bar;
=> x + 9 = −6
=> x = -6 - 9
=> x = -15

Two buildings are 18 m part. The shorter building is 12 m high while the taller one is 19 m high. Find the distance, x m between the top of the buildings.
The distance between the tops of the buildings is 28.5 meters.
To find the distance between the top of the buildings, we can use the concept of similar triangles.
Let's denote the height of the shorter building as "a" (12 m) and the height of the taller building as "b" (19 m). The distance between the buildings can be denoted as "c" (18 m), and the distance between the top of the buildings as "x" (which we need to find).
We can set up a proportion based on the similar triangles formed by the buildings:
a/c = b/x
Substituting the known values:
12/18 = 19/x
To find "x," we can cross-multiply and solve for "x":
12x = 18 * 19
12x = 342
x = 342/12
x = 28.5 m
Therefore, the distance between the tops of the buildings is 28.5 meters.

A route that an object in space follows around another is known as an orbit. A satellite is a thing that orbits the earth. An Earth- or moon-like natural satellite is one possibility. Moons are satellites that orbit many planets. A man-made satellite is also possible, such as the International Space Station.
The belt of asteroids is located between the orbits of Mars and Jupiter. The asteroids in this region, known as the main belt, are made up of small rocky bodies that orbit the sun in a region between about 2.2 and 3.2 astronomical units (AU) from the sun.
The distance from the sun to the Earth is about 1 AU, and the distance from the sun to Venus is about 0.7 AU, so the main belt is located beyond the orbits of both Venus and Earth.

Part D. Given the sample selected for this study, what type of bias do you think might apply? How would you suggest selecting a sample that better avoids sample bias? (4 points)
using techniques such as anonymity or confidentiality to encourage honest and open responses.
There are several potential sources of bias that could be present in the sample selected for this study. One possible source of bias is selection bias, which occurs when the sample is not representative of the population from which it was drawn. This can happen if certain groups of people are more likely to be included in the sample than others, or if some individuals are more likely to participate in the study than others.
Another potential source of bias is response bias, which occurs when participants provide inaccurate or incomplete information in their responses. This can happen if participants feel uncomfortable sharing certain information, or if they have a particular agenda or bias that influences their responses.
To avoid sample bias, researchers should aim to select a sample that is as representative as possible of the population they are interested in studying. One way to do this is to use random sampling techniques, such as simple random sampling or stratified random sampling, to ensure that every member of the population has an equal chance of being included in the sample. Additionally, researchers can take steps to minimize response bias by using clear and unbiased survey questions, providing a comfortable and non-judgmental environment for participants to provide their responses.
