Step-by-step explanation:
The following estimates were provided; MPL 20-0.4L; and APL= 20-0,2L-320/L i. Over what range of l (variable inputs) should production take place? ii. What is the range of output over the range of labour in (i)
Answer: To determine the range of input (L) over which production should take place, we need to find the point at which the marginal product of labor (MPL) is zero:
MPL = 20 - 0.4L
0 = 20 - 0.4L
0.4L = 20
L = 50
So production should take place for values of L less than or equal to 50.
To find the range of output over this range of labor, we can use the average product of labor (APL) equation:
APL = 20 - 0.2L - 320/L
Substituting L = 50, we get:
APL = 20 - 0.2(50) - 320/50
APL = 20 - 10 - 6.4
APL = 3.6
So the range of output over the range of labor from 0 to 50 is approximately 0 to 3.6 units of output.

Find the
-coordinates at which the tangent line to =(x−6/x)^8
is horizontal.
The coordinates at which the tangent line to f(x) = (x-6/x)^8 is horizontal are (√6, f(√6)) and (-√6, f(-√6)), where f(x) is the given function.
Coordinates calculation.
To find the coordinates at which the tangent line to the function f(x) = (x-6/x)^8 is horizontal, we need to find the critical points of the function where the derivative is zero or undefined.
First, let's find the derivative of the function:
f(x) = (x-6/x)^8
f'(x) = 8(x-6/x)^7 * (1 - (-6/x^2))
Simplifying the second term, we get:
f'(x) = 8(x-6/x)^7 * (x^2+6)/x^2
Now we need to set the derivative equal to zero and solve for x:
8(x-6/x)^7 * (x^2+6)/x^2 = 0
(x^2+6) cannot be zero, so we can ignore that factor.
8(x-6/x)^7 = 0
(x-6/x) = 0
x^2 - 6 = 0
x = ±√6
So we have two critical points at x = √6 and x = -√6.
Now we need to determine whether these critical points correspond to a maximum, minimum, or inflection point. To do this, we can use the second derivative test.
Taking the derivative of the first derivative, we get:
f''(x) = 8(x-6/x)^6 * (56/x^3 + 7)
Evaluating the second derivative at x = √6, we get:
f''(√6) = 8(√6-6/√6)^6 * (56/√6^3 + 7)
f''(√6) > 0, so the function has a local minimum at x = √6.
Evaluating the second derivative at x = -√6, we get:
f''(-√6) = 8(-√6-6/-√6)^6 * (56/-√6^3 + 7)
f''(-√6) < 0, so the function has a local maximum at x = -√6.
Therefore, the coordinates at which the tangent line to f(x) = (x-6/x)^8 is horizontal are (√6, f(√6)) and (-√6, f(-√6)), where f(x) is the given function.

One function, f(x), is defined as f(x) = (x + 4)2 - 3. A second function, g(x), is a parabola that passes through the points shown in the table below. What is the absolute value of the difference between the y-intercepts of f(x) and g(x)? 17 15 9 6
According to the given information, the absolute value of the difference between the y-intercepts of f(x) and g(x) is 0.
What is a function?
A function is a relation between a set of inputs and a set of possible outputs, with the property that each input is related to exactly one output.
To find the y-intercept of a function, we set x=0 and evaluate the function at that value.
For the function f(x) = (x + 4)2 - 3, we have:
f(0) = (0 + 4)2 - 3 = 13.
To find the y-intercept of the function g(x), we can use the given points and try to write it in the form y = ax² + bx + c, where a, b, and c are constants.
Using the given points, we can write three equations:
When x = -2, y = 17: 17 = 4a - 2b + c
When x = -1, y = 15: 15 = a - b + c
When x = 1, y = 9: 9 = a + b + c
Solving this system of equations, we get a = -1, b = 1, and c = 13. Therefore, the equation of the function g(x) is:
g(x) = -x² + x + 13.
To find the absolute value of the difference between the y-intercepts of f(x) and g(x), we can subtract the two y-intercepts and take the absolute value:
|f(0) - g(0)| = |13 - 13| = 0.
Therefore, the absolute value of the difference between the y-intercepts of f(x) and g(x) is 0.

Answer:
C) decreasing then increasing.
Step-by-step explanation:
A function is said to be increasing if the y-values increase as the x-values increase.
A function is said to be decreasing if the y-values decrease as the x-values increase.
From inspection of the given graph of y = x², we can see that for the first half of the graph, the y-values are decreasing as the x-values increase. Therefore, the function is decreasing for this part of the graph.
Similarly, for the second half of the graph, we can see that the y-values are increasing as the x-values increase. Therefore, the function is increasing for this part of the graph.
So the description of the graph of the function is:
C) decreasing then increasing.If OS is a radius perpendicular to chord WV and intercepts it at point M. Find MW.
Answer:
o find MW, we need to use the fact that OS is perpendicular to WV, which means that OS is also perpendicular to MW since it bisects WV.
Let's label the midpoint of WV as point N. Then we can use the Pythagorean theorem to find MW.
First, we need to find the length of ON. Since OS is a radius of the circle, it is equal to the radius of the circle, which we can call r. Then, using the Pythagorean theorem, we have:
ON^2 = OS^2 - SN^2
ON^2 = r^2 - (WV/2)^2
ON^2 = r^2 - (MW/2)^2 (since NW = MV)
Next, we need to find the length of MN. We know that OM is half of WV, so OM = WV/2. Then, using the Pythagorean theorem again, we have:
MN^2 = ON^2 + OM^2
MN^2 = r^2 - (MW/2)^2 + (WV/2)^2
MN^2 = r^2 - (MW/2)^2 + (2MW/2)^2 (since WV = 2MW)
MN^2 = r^2 - (MW/2)^2 + MW^2
Finally, we can solve for MW by using the Pythagorean theorem one more time:
MW^2 = MN^2 + NW^2
MW^2 = (r^2 - (MW/2)^2 + MW^2) + (MW/2)^2
MW^2 = r^2 - (MW/2)^2 + MW^2/4 + MW^2/4
MW^2 = r^2 - (MW/2)^2 + MW^2/2
Multiplying both sides by 4 gives:
4MW^2 = 4r^2 - MW^2 + 2MW^2
3MW^2 = 4r^2
MW^2 = 4r^2/3
MW = 2r/sqrt(3)
Therefore, the length of MW is 2r/sqrt(3).

Use the graph that shows the solution to f(x)=g(x). f(x)=x2 g(x)=(12)x−1 What is the solution to f(x)=g(x)?
x=−1
x = 0
x = 1
x = 2
Answer:
To find the solution to f(x)=g(x), we need to find the point(s) where the two curves intersect.
The graph is not provided, but we can find the solution algebraically by setting the two functions equal to each other:
f(x) = g(x)
x^2 = 12^(x-1)
To solve for x, we can take the logarithm of both sides:
log(x^2) = log(12^(x-1))
2log(x) = (x-1)log(12)
2log(x) = xlog(12) - log(12)
2log(x) - xlog(12) = -log(12)
log(x^2) - log(12^x) = -log(12)
log(x^2/12^x) = -log(12)
log(x/12) = -log(12)
log(x) - log(12) = -log(12)
log(x) = 0
x = 1
Therefore, the solution to f(x)=g(x) is x=1.

An employee at a department store is stocking cell phone cases. He has a box of 80 cases. Among the 80 cases, 40 are black, 10 are white, and 30 are pink.
If he reaches into the bag randomly and removes one at a time, what is the probability that the first three cases are all pink?
2Points
The probability that the first three cases are all pink is 0.015. In most cases, the probability is given as a ratio between the total number of outcomes in the sample space and the number of positive outcomes.
What exactly is probability in mathematics?Probability is the potential for something to occur. The value is expressed in the range of 0 to 1 .In light of this, whenever we are unsure of how an event will turn out, we can talk about the probabilities of various outcomes, or how likely they are.
Statistics is a term that refers to the study of probability-based phenomena. Hence, the probability that an event will occur depends on both the quantity of favorable outcomes and the total number of outcomes.
Probability = no. of favorable cases/total number of cases
Given
Total No. of cases = 80
Black = 40
White = 40
Pink = 30
Probability = no. of favorable cases/total number of cases
For first draw
Pink cases = 10
Total cases = 80
P1 = 10/80
For second draw
Pink cases left = 9
Total cases = 79
P2 = 9/79
For second draw
Pink cases left = 8
Total cases = 78
P2 = 8/78
Now Total Probability is
P = P1× P2 × P3
P = 10/80 × 9/79 × 8/78 = 720/492,960

How to get the value of x and y?We know that the sum of two adjacent angles is always 180°, then we can write two linaer equations:
8y + 4x + 26 = 180
4y - 12 + 3x = 180
We can simplify that to get the system of equations:
4x + 8y = 154
3x + 4y = 192
To solve this, we can take the difference between twice the second equation and once the first equation to get:
2*(3x + 4y) - (4x + 8y) = 2*192 - 154
6x + 8y - 4x - 8y = 230
2x = 230
x = 230/2
x = 115

In politics, marketing, etc. we often want to estimate a percentage or proportion p . One calculation in statistical polling is the margin of error - the largest (reasonble) error that the poll could have. For example, a poll result of 72% with a margin of error of 4% indicates that p is most likely to be between 68% and 76% (72% minus 4% to 72% plus 4%). In a (made-up) poll, the proportion of people who like dark chocolate more than milk chocolate was 32% with a margin of error of 2.2% . Describe the conclusion about p using an absolute value inequality. Be sure to use decimal numbers in your answer (such as using 0.40 for 40%).
The conclusion about p using an absolute value inequality is in the range of 29.8% to 34.2%.
What is absolute value inequality?
An expression using absolute functions and inequality signs is known as an absolute value inequality.
We know that the absolute value inequality about p using an absolute value inequality is written as,
[tex]|p-\hat{p}|\leq E[/tex]
where E is the margin of error and is the sample proportion.
Now, it is given that the poll result of 72% with a margin of error of 4% indicates that p is most likely to be between 68% and 76%. Therefore, p can be written as,
[tex]|p-0.72|\leq 0.04\\(0.72-0.04)\leq p\leq (0.72+0.04)\\\\0.68 \leq p \leq 0.76[/tex]
Thus, the p is most likely to be between the range of 68% to 76%.
Similarly, the proportion of people who like dark chocolate more than milk chocolate was 32% with a margin of error of 2.2%. Therefore, p can be written as,
[tex]|p-0.32| \leq 0.022\\\\0.248 \leq p \leq 0.342[/tex]
Thus, the p is most likely to be between the range of 29.8% to 34.2%.

In 2018 Gallup poll, it was reported that about 5% of Americans identify themselves as vegetarians. You think that percent is higher in the age group 18 to 35 years. Test your hypothesis at 5% level of significance.
At a 5% level of significance, we reject the null hypothesis and conclude that there is evidence to support the alternative hypothesis that the percentage of vegetarians in age group 18 to 35 years is higher than 5%.
To test the hypothesis that the percentage of vegetarians is higher in the age group 18 to 35 years at a 5% level of significance, we can use a hypothesis test with the following null and alternative hypotheses:
Null hypothesis (H0): The percentage of vegetarians in the age group 18 to 35 years is equal to 5%.
Alternative hypothesis (Ha): The percentage of vegetarians in the age group 18 to 35 years is greater than 5%.
We can conduct a one-tailed z-test to test this hypothesis, using the following formula:
z = (p - P0) / sqrt(P0 * (1 - P0) / n)
where:
p is the sample proportion of vegetarians in the age group 18 to 35 years
P0 is the hypothesized proportion (5%)
n is the sample size
We will reject the null hypothesis if the calculated z-value is greater than the critical z-value corresponding to a 5% level of significance (one-tailed test).
Assuming a sample of size n = 100, if we find that 10 people in the sample identify themselves as vegetarians, then the sample proportion is:
p = 10/100 = 0.1
Using the formula above, we can calculate the z-value:
z = (0.1 - 0.05) / sqrt(0.05 * 0.95 / 100) = 1.96

B
Answer:
Step-by-step explanation:
In the given figure, we have three circles arranged such that they touch each other. Let the centers of these circles be A, B, and C, with radii 5.4, 4.4, and 3.4, respectively.
We can see that triangle ABC is an equilateral triangle, since all sides are of equal length (the radii of the circles).
To find the angle A, we can use the law of cosines, which states that:
c^2 = a^2 + b^2 - 2ab cos(C)
where a, b, and c are the lengths of the sides of a triangle, and C is the angle opposite the side of length c.
Since triangle ABC is equilateral, we have a = b = c, and C = 60°. Therefore, we can rewrite the above equation as:
c^2 = 2a^2 - 2a^2 cos(60°)
Simplifying and solving for a, we get:
a = c / sqrt(3)
Substituting the given values, we have:
a = 4.4 / sqrt(3) ≈ 2.54
Therefore, angle A is:
A = 180° - 60° - 60° = 60°
And angle B is:
B = 180° - A = 120°
Finally, we can use the law of sines to find the length of side c:
sin(A) / a = sin(B) / b = sin(C) / c
Substituting the values we have found, we get:
sin(60°) / 2.54 = sin(120°) / c
Simplifying and solving for c, we get:
c = 2.54 / sqrt(3) / sin(120°) ≈ 3.71
Therefore, the length of side c is approximately 3.71, and angle B is 120°.

Suppose you are the building rectangular puppy kennel for your new puppy with 25 feet of fence. The side of the kennel next to your house does not need a fence.this side is 9 feet long. Find the dimensions of the kennel.
The required dimensions of the kennel are 17 feet by 8.5 feet.
How to find the dimensions?Let the length of the kennel be L and the width be W.
We know that the total length of fence available is 25 feet. Since one side of length 9 feet does not need fencing, the total length of the other three sides that need fencing is (L + 2W - 9).
Therefore, we have:
25 = L + 2W - 9
Simplifying the equation, we get:
L + 2W = 34
We also know that the area of the kennel is given by:
Area = Length x Width
Substituting L = 34 - 2W from the first equation into the above equation, we get:
Area = (34 - 2W) x W
Simplifying the equation, we get:
Area = 34W - 2W²
To maximize the area, we differentiate the above equation with respect to W, set it equal to zero, and solve for W:
d(Area)/dW = 34 - 4W = 0
Solving for W, we get:
W = 8.5
Substituting this value of W back into the equation L + 2W = 34, we get:
L + 2(8.5) = 34
L + 17 = 34
L = 17
Therefore, the dimensions of the kennel are 17 feet by 8.5 feet.

Part Two!
Angela worked on a straight 11%
commission. Her friend worked on a salary of $950
plus a 7%
commission. In a particular month, they both sold $23,800
worth of merchandise.
Step 2 of 2 : How much did her friend earn for the same month? Follow the problem-solving process and round your answer to the nearest cent, if necessary.
Angela's friend earned a salary of $950 plus a commission of $1,599.50 for a total earnings of $2,549.50 in the month they both sold $23,800 worth of merchandise.
To find out how much Angela's friend earned in the same month, we need to first calculate their commission earnings.
Angela's commission earnings can be found by multiplying the total sales by her commission rate of 11%:
Commission earnings = $23,800 x 0.11 = $2,618
Now, let's calculate her friend's commission earnings. First, we need to subtract the salary from the total sales:
Total sales - Salary = Commissionable sales
$23,800 - $950 = $22,850
Next, we can calculate the commission earnings by multiplying the commissionable sales by the commission rate of 7%:
Commission earnings = $22,850 x 0.07 = $1,599.50
Adding the commission earnings to the salary gives us the total earnings for the month:
Total earnings = $950 + $1,599.50 = $2,549.50
Therefore, Angela's friend earned $2,549.50 for the same month.

An airplane flying into a headwind travels the 1560-mile flying distance between two cities in 3 hours. On the return flight, the airplane travels this distance in 2 hours and 30 minutes. Find the airspeed of the plane (in mi/h) and the speed of the wind (in mi/h), assuming that both remain constant.
airspeed mi/h
wind speed mi/h
So the speed of the wind is 52 miles per hour. When the airplane is flying into a headwind, its ground speed (the speed at which it appears to be moving relative to the ground)
what is speed ?
In physics, speed is the rate at which an object moves, or the distance traveled per unit of time. It is a scalar quantity, meaning that it has magnitude (a numerical value) but no direction.
In the given question,
Let's use "s" to represent the airspeed of the plane, and "w" to represent the speed of the wind.
When the airplane is flying into a headwind, its ground speed (the speed at which it appears to be moving relative to the ground) is s - w. We know that the airplane travels 1560 miles in 3 hours, so we can set up the equation
1560 = (s - w) * 3
Simplifying this equation, we get:
s - w = 520
When the airplane is flying with a tailwind (i.e., in the opposite direction of the headwind), its ground speed is s + w. We know that the airplane travels 1560 miles in 2.5 hours (since 2 hours and 30 minutes is equal to 2.5 hours), so we can set up the equation:
1560 = (s + w) * 2.5
Simplifying this equation, we get:
s + w = 624
Now we have two equations:
s - w = 520
s + w = 624
We can solve this system of equations by adding them together. When we add the left sides of the equations, we get:
2s = 1144
Dividing both sides by 2, we get:
s = 572
So the airspeed of the plane is 572 miles per hour.
Now we can use one of the equations we found earlier to solve for the wind speed. Let's use the equation:
s - w = 520
Substituting s = 572, we get:
572 - w = 520
Simplifying this equation, we get:
w = 52
So the speed of the wind is 52 miles per hour.
