For the given cost function C(x) = 40000 + 800x + x2 find: a) The cost at the production level 1900 b) The average cost at the production level 1900 c) The marginal cost at the production level 1900 d) The production level that will minimize the average cost e) The minimal average cost
Answers
According to the cost function,
a) The cost at the production level 1900 is $4,439,000.
b) The average cost at the production level 1900 is $2,336.32.
c) The marginal cost at the production level 1900 is $4,600.
d) The production level that will minimize the average cost is 1900 units.
e) The minimal average cost is $2,336.32.
The cost function that we will be focusing on is C(x) = 40000 + 800x + x², where x represents the level of production. This function tells us the total cost of producing x units of a product. Let's dive into the questions at hand:
a) To find the cost at the production level 1900, we simply plug in x = 1900 into the cost function: C(1900) = 40000 + 800(1900) + (1900)² = $4,439,000.
b) To find the average cost at the production level 1900, we need to divide the total cost by the level of production: AC(1900) = C(1900)/1900 = $2,336.32. The average cost tells us the cost per unit of production at a given level of output.
c) The marginal cost represents the additional cost of producing one additional unit of a product. It is the derivative of the cost function with respect to x: MC(x) = dC(x)/dx = 800 + 2x. To find the marginal cost at the production level 1900, we plug in x = 1900: MC(1900) = 800 + 2(1900) = $4,600.
d) To find the production level that will minimize the average cost, we need to take the derivative of the average cost function with respect to x and set it equal to zero. This is because the average cost function reaches its minimum at the point where its slope is zero. So, we have:
d/dx (AC(x)) = d/dx (C(x)/x) = (dC(x)/dx)/x - C(x)/x² = 0
Simplifying, we get:
800 + 2x = C(x)/x²
Plugging in C(x) = 40000 + 800x + x², we get:
800 + 2x = (40000/x) + 800 + x
Simplifying further, we get:
x = 1900
e) Finally, to find the minimal average cost, we simply plug in x = 1900 into the average cost function: AC(1900) = $2,336.32.

What is the length of line HI and IJ
Answers
Point H is even with point E and I is exactly half way in between E and F. EF = 40 half of that is 20. This also works with HG, BC, and JK.
HI and IJ are the same length so both are 20mm
Answer:
HI = \(4\sqrt{41}\) , IJ = \(4\sqrt{41}\)
Step-by-step explanation:
The number of AB spaces is 15, the BC is 20, and the CD is 15. Looking at the given length, you can see that it is twice the number of cells.
If you draw a line perpendicular to the line HG in I, it becomes a right triangle. The lengths of HI and IJ can be calculated using Pythagoras on a right triangle.
Suppose that the vertical line is L.
HL = 10
IL = 8
(HI)² = (HL)²+ (IL)² = 10²+8²=164
HI = \(2\sqrt{41\\\) -> (It's twice the number of spaces.) -> HI = \(4\sqrt{41}\)
IJ can be obtained in the same way.
IJ = \(2\sqrt{41\\\) -> (It's twice the number of spaces.) -> IJ = \(4\sqrt{41}\)

A. The manager of a small business reported 30 days of profit which revealed that $200 was made on the first day, $210 on the second day, $220 on the third day and so on.
i. Determine the general rule that can be used to find the profit for each day. (2 marks)
ii. What is the difference between the profit made on the 17ℎ and 23 day? (3 marks
) iii. In total, calculate how much profit was made over the course of the 30 days if the profit follows the same pattern throughout the period.
Answers
i. The general rule to find the profit for each day can be determined by observing that the profit increases by $10 each day. Therefore, the general rule can be expressed as:
Profit = $200 + ($10 × Day)
ii. To find the difference between the profit made on the 17th and 23rd day, we need to subtract the profit on the 17th day from the profit on the 23rd day. Using the general rule from part i, we can calculate:
Profit on 17th day = $200 + ($10 × 17) = $200 + $170 = $370
Profit on 23rd day = $200 + ($10 × 23) = $200 + $230 = $430
Difference = Profit on 23rd day - Profit on 17th day = $430 - $370 = $60.
iii. To calculate the total profit made over the course of the 30 days, we can use the formula for the sum of an arithmetic series. The first term is $200, the common difference is $10, and the number of terms is 30.
Total Profit = (n/2) * (2a + (n-1)d)
= (30/2) * (2 * $200 + (30-1) * $10)
= 15 * ($400 + 290)
= 15 * $690
= $10,350.
Therefore, the total profit made over the 30-day period following the same pattern is $10,350.

If the percentage of scores falling between the mean and a z score of 0.40 is 15.54, then what is the percentage of scores falling between the mean and a z score of –0.40? A. -15.54 B. 15.54 C. 34.46 D.-34.46
Answers
The correct answer is C. 34.46.
This is because the area between the mean and a positive z score of 0.40 is 15.54%, which means the area between the mean and a negative z score of -0.40 is also 15.54%.
Therefore, the total area between the mean and a z score of -0.40 is the sum of the area to the left of the mean (which is 50%) and the area between the mean and a z score of -0.40 (which is 15.54%).
Total area between the mean and a z score of -0.40 = 50% + 15.54% = 65.54%.
To find the percentage of scores falling between the mean and a z score of -0.40, we subtract the area to the left of the z score from the total area between the mean and the z score:
Percentage of scores falling between the mean and a z score of -0.40 = Total area between the mean and a z score of -0.40 - Area to the left of the z score
= 65.54% - 50%
= 15.54%.
Therefore, the percentage of scores falling between the mean and a z score of -0.40 is 15.54%.

The percentage of scores falling between the mean and a z score of –0.40 is also 15.54%. So the correct answer is B.
15.54.
This is because the normal distribution is symmetric around the mean, so the percentage of scores between the mean
and a positive z score is the same as the percentage of scores between the mean and the same negative z score.
This is because the area under the normal curve between a z score of 0.40 and –0.40 is symmetrical, meaning it is the
same on both sides of the mean.
Therefore, the percentage of scores falling between the mean and a z score of –0.40 is equal to the percentage of
scores falling between the mean and a z score of 0.40, which is 15.54%.

Suppose a large shipment of laptop computers contained 15% defectives. If a sample of size 294 is selected, what is the probability that the sample proportion will be less than 14%
Answers
Using the normal distribution, it is found that there is a 0.3156 = 31.56% probability that the sample proportion will be less than 14%.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean \(\mu\) and standard deviation \(\sigma\) is given by:
\(Z = \frac{X - \mu}{\sigma}\)
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.By the Central Limit Theorem, for a proportion p in a sample of size n, the sampling distribution of sample proportion is approximately normal with mean \(\mu = p\) and standard deviation \(s = \sqrt{\frac{p(1 - p)}{n}}\), as long as \(np \geq 10\) and \(n(1 - p) \geq 10\).The proportion and the sample size are given, respectively, by:
p = 0.15, n = 294
Hence the mean and the standard error are given, respectively, by:
\(\mu = p = 0.15\)\(s = \sqrt{\frac{p(1 - p)}{n}} = \sqrt{\frac{0.15(0.85)}{294}} = 0.0208\)The probability is the p-value of Z when X = 0.14, hence:
\(Z = \frac{X - \mu}{\sigma}\)
By the Central Limit Theorem:
\(Z = \frac{X - \mu}{s}\)
\(Z = \frac{0.14 - 0.15}{0.0208}\)
Z = -0.48
Z = -0.48 has a p-value of 0.3156.
0.3156 = 31.56% probability that the sample proportion will be less than 14%.

a puck company wants to sponsor the players with the 10% quickest goals in hockey games. the times of first goals are normally distributed with a mean of 12.56 minutes and a standard deviation of 8.73 minutes. how fast would a player need to make a goal to be sponsored by the puck company?
Answers
A player would need to make a goal in less than 6.78 minutes to be sponsored by the puck company.
This is because 10% of goals are made in less than one standard deviation below the mean, which is 12.56 - (8.73 * 0.67) = 6.78 minutes. This is assuming that the distribution of goal times follows a normal distribution, which is a common assumption for many real-world data sets.
The standard deviation is a measure of how spread out the data is, and by multiplying it by 0.67, we can find the point that represents the 10th percentile of the data. In this case, the 10th percentile of goal times is less than 6.78 minutes, meaning that the top 10% of goal times fall below this threshold.

THANKS FOR THE HELP!!!
Answers
Answer:
Since this is a multi-part question, just look at the bolded parts under each letter. I hope this helps a bit ;)
Step-by-step explanation:
A)
All sides of a square are congruent. "s" represents the square's perimeter:
s=4x.
"r" is the rectangle's perimeter:
r= 4x+26
since the perimeter = 2W + 2L:
2W + 2L= 4x+ 26
and W=x, so:
2x + 2L= 4x + 26
Subtract from both sides:
2L= 2x +26
Divide both sides:
the length of the rectangle "L"= x +13.
B) Plug 5 into the equations:
L= 5+ 13 or 18.
2(18) + 2(5)= r
36+ 10 = r or 46
s= s+ 26
s= 46-26 or 20.
20/4= 5...
It seems (at least to me, feel free to give constructive criticism) that the only logical conclusion is that 5 could be the value of x.
C) You would likely need to use substitution to solve, but unless I am much mistaken, this looks like an infinite-solutions equation.

Which sequence exhibits the similarity between rectangles ABCD which A’B’C’D’ shown in the coordinates plane below
Answers
The sequence of transformation that exhibits the similarity between the rectangles ABCD and rectangle A'B'C'D' is the option C.
C. Rectangle ABCD is reflected across the y-axis and then dilated by a scale factor of 2 with the center of dilation at the origin to obtain rectangle A'B'C'D'
What is a reflection transformation in geometry?A reflection transformation of an object gives or produces the mirror image of the object about a specified line.
The coordinates of the points of the rectangle ABCD obtained from the graph are; A(-4, -4), B(-4, 4), C(2, 4), and D(2, -4).
The coordinates of the image of the rectangle ABCD (rectangle (A'B'C'D') are; A'(8, -8), B'(8, 8), C'(-4, 8) and D'(-4, -8)
The coordinates of the reflection of the point (x, y), following a reflection across the y-axis is the point (-x, y)
The vertices of the image of rectangle ABCD formed following a reflection across the x-axis are therefore;
A(-4, -4) \(\underrightarrow{R_{x-axis}}\) A''(4, -4)
B(-4, 4) \(\underrightarrow{R_{x-axis}}\) B''(4, 4)
C(2, 4) \(\underrightarrow{R_{x-axis}}\) C''(-2, 4)
D(2, -4) \(\underrightarrow{R_{x-axis}}\) D''(-2, -4)
The coordinates of the point (x, y) following a dilation by a scale factor of k, with the center of dilation at the origin is (k·x, k·y)
The dilation of the image of the rectangle ABCD by a scale factor of 2 gives;
A''(4, -4) \(\underrightarrow{D_{2}}\) (2×4, 2×(-4)) = A'(8, -8)
B''(4, 4) \(\underrightarrow{D_{2}}\) (2×4, 2×(4)) = B'(8, 8)
C''(-2, 4) \(\underrightarrow{D_{2}}\) (2×(-2), 2×(4)) = C'(-4, 8)
D''(-2, -4) \(\underrightarrow{D_{2}}\) (2×(-2), 2×(-4)) = D'(-4, -8)
The points of the image of rectangle ABCD following a a reflection and a dilation are A'(8, -8), B'(8, 8), C'(-4, 8) and D'(-4, -8), which are the same as the coordinates of the points of the given rectangle A'B'C'D'

Answers
Answer:
C. 142°
Step-by-step explanation:
You want the angle between vectors u=3i+√3j and v=-2i-5j.
AngleThere are a number of ways the angle between the vectors can be found. For example, the dot-product relation can give you the cosine of the angle:
u•v = |u|·|v|·cos(θ) . . . . . . where θ is the angle of interest
You can find the angles of the vectors individually, and subtract those:
u = |u|∠α
v = |v|∠β
θ = α - β
When the vectors are expressed as complex numbers, the angle between them is the angle of their quotient:
\(\dfrac{\vec{u}}{\vec{v}}=\dfrac{|\vec{u}|\angle\alpha}{|\vec{v}|\angle\beta}=\dfrac{|\vec{u}|}{|\vec{v}|}\angle(\alpha-\beta)=\dfrac{|\vec{u}|}{|\vec{v}|}\angle\theta\)
This method is used in the calculation shown in the first attachment. The angle between u and v is about 142°.
A graphing program can draw the vectors and measure the angle between them. This is shown in the second attachment.
__
Additional comment
The approach using the quotient of the vectors written as complex numbers is simply computed using a calculator with appropriate complex number functions. There doesn't seem to be any 3D equivalent.
The dot-product relation will work with 3D vectors as well as 2D vectors.

Let's assume the width of the rectangle movie screen is represented by 'w' feet. According to the given information, the length of the screen is 303030 feet longer than the width. Therefore, the length can be expressed as 'w + 303030' feet.
The perimeter of a rectangle is given by the formula: 2(length + width). In this case, the perimeter of the movie screen is 148148148 feet. We can set up the equation as follows:
2(w + (w + 303030)) = 148148148.
Simplifying the equation, we have:
2(2w + 303030) = 148148148.
4w + 606060 = 148148148.
4w = 147542088.
Dividing both sides by 4, we get:
w = 36885522.
Therefore, the width of the screen is 36885522 feet. Since the length is 303030 feet longer than the width, we can calculate the length as:
Length = Width + 303030 = 36885522 + 303030 = 37188552 feet.
Hence, the length of the movie screen is 37188552 feet.

The shape below has rotational symmetry.
(b) Write down the order of rotational symmetry.
Answers
The order of rotational symmetry is the number of times a shape can be rotated and still look the same.
What is the order of rotational symmetry?Generally, The amount of times that a form may be rotated through 360 degrees with maintaining its appearance is referred to as its rotational symmetry.
For instance, a circle has an order of rotational symmetry of infinity, which means that it can be rotated any number of times and still look the same.
On the other hand, a square has an order of rotational symmetry of 4, which means that it can be rotated by 90 degrees four times while maintaining its original appearance.

If s(x) = 2 – x2 and t(x) = 3x, which value is equivalent to (s circle t) (negative 7)? HALP
Answers
-439 is the value which is equivalent to (s circle t) (negative 7).
Given,
s(x) = 2 - x²
t(x) = 3x
We have to find the value which is equivalent to (s circle t) (negative 7)
That is,
(s circle t) (negative 7) : This is a notation for compound function.
A function that takes another function as an argument is referred to as a compound function.
s(t(-7)) is the alternative notation for this compound function, which means that the value obtained from the function t(-7) will be used in the function s. (x).
Now, let's calculate the value of t(-7):
That is,
t(x) = 3x
t(-7) = 3 × (-7) = -21
Next, apply the value of t(-7) for s(x)
That is,
s(x) = 2 - x²
s(t(-7)) = s(-21) = 2 - (-21)^2 = 2 - 441 = -439
That is, -439 is the value which is equivalent to (s circle t) (negative 7).
