Boeing takes 29,454 hours to produce the fifth 787 jet. With an 80% learning factor, the time required for the production of the eleventh 787 is approximately 66,097 hours.
To calculate the time required for the production of the eleventh 787 jet, we can use the learning curve formula:
T₂ = T₁ × (N₂/N₁)^b
Where:
T₂ is the time required for the second unit (eleventh in this case)
T₁ is the time required for the first unit (fifth in this case)
N₂ is the quantity of the second unit (11 in this case)
N₁ is the quantity of the first unit (5 in this case)
b is the learning curve exponent (log(1/LF) / log(2))
Given that T₁ = 29,454 hours and LF (learning factor) = 80% = 0.8, we can calculate b:
b = log(1/LF) / log(2)
b = log(1/0.8) / log(2)
b ≈ -0.3219 / -0.3010
b ≈ 1.0696
Now, substituting the given values into the formula:
T₂ = 29,454 × (11/5)^1.0696
Calculating this expression, we find:
T₂ ≈ 29,454 × (2.2)^1.0696
T₂ ≈ 29,454 × 2.2422
T₂ ≈ 66,096.95
Rounding the result to the nearest whole number, the time required for the production of the eleventh 787 jet is approximately 66,097 hours.

A firm has a has Cobb-Douglas production function
q=ALaKb
Use calculus to find the cost minimizing capital-labor ratio. Let the cost of labor (L) be w and let the cost of capital (K) be r. Suppose the firm is trying to achieve a level of output indicated by "q."
For simplicity, let a+b=1.
The cost-minimizing value of L (as a function of q,w,r,a, and b ) is
L=___. (Properly format your expression using the tools in the palette. Hover over tools to see keyboard shortcuts. E.g., a superscript can be created with the character.)
The cost-minimizing value of labor (L) as a function of q, w, r, a, and b is:
L = ((b/a) * (qwar)^ (1 - 1/b) * (A^ (1 - 1/b))) ^ (1 / (a - 1))
To find the cost-minimizing value of labor (L) as a function of output (q), the cost of labor (w), the cost of capital (r), and the Cobb-Douglas production function parameters (a and b), we can use the concept of minimizing the cost function subject to the production function constraint.
Given the Cobb-Douglas production function: q = AL^a * K^b
The cost function is given by: C = wL + rK
To minimize the cost function, we need to find the optimal value of L that minimizes the cost while producing the desired output level (q).
We can start by rearranging the Cobb-Douglas production function to solve for K:
K = (q / (AL^a))^ (1/b)
Substitute this expression for K in the cost function:
C = wL + r * ((q / (AL^a))^ (1/b))
To minimize the cost function, we differentiate it with respect to L and set the derivative equal to zero:
dC/dL = w - (ar/q) * ((q / (AL^a))^ (1/b)) * (1/b) * (AL^a)^ (1/b - 1) * aL^(a-1)
Setting dC/dL = 0 and solving for L:
w - (ar/q) * ((q / (AL^a))^ (1/b)) * (1/b) * (AL^a)^ (1/b - 1) * aL^(a-1) = 0
Simplifying the equation:
w = (ar/q) * (AL^a)^ (1/b - 1) * aL^(a-1)
Divide both sides of the equation by w:
1 = (ar/qw) * (AL^a)^ (1/b - 1) * aL^(a-1)
Rearranging the equation:
L^(1 - a) = (qwar)^ (1/b - 1) * (A^ (1/b - 1)) * a/b
Taking the reciprocal of both sides:
L^ (a - 1) = (b/a) * (qwar)^ (1 - 1/b) * (A^ (1 - 1/b))
Taking the power of (1 / (a - 1)) on both sides:
L = ((b/a) * (qwar)^ (1 - 1/b) * (A^ (1 - 1/b))) ^ (1 / (a - 1))
Therefore, the cost-minimizing value of labor (L) as a function of q, w, r, a, and b is:
L = ((b/a) * (qwar)^ (1 - 1/b) * (A^ (1 - 1/b))) ^ (1 / (a - 1))

Let A and B be events with P ( A) = 0.3, P (B) = 0.79, and P(BA)
= 0.7
Find P(A and B) =
.
The probability of the intersection of events A and B, P(A and B), is equal to 0.7.
What is probability?Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about the likelihood of an event happening, or how likely it is.
The probability of the intersection of events A and B, denoted as P(A and B) or P(A ∩ B), can be found using the formula:
P(A and B) = P(BA) = P(A) * P(B | A)
Given the information provided:
P(A) = 0.3
P(B) = 0.79
P(BA) = 0.7
We can use the formula to calculate P(A and B):
P(A and B) = P(BA) = P(A) * P(B | A) = 0.3 * P(B | A)
To find P(B | A), we can use the formula for conditional probability:
P(B | A) = P(BA) / P(A)
Substituting the values:
P(B | A) = P(BA) / P(A) = 0.7 / 0.3
Now, let's calculate P(A and B):
P(A and B) = P(BA) = P(A) * P(B | A) = 0.3 * P(B | A) = 0.3 * (0.7 / 0.3) = 0.7
Therefore, the probability of the intersection of events A and B, P(A and B), is equal to 0.7.

The diagram shows a shaded parallelogram drawn inside a rectangle. What is the area of the shaded parallelogram? 4 cm 10 cm 4 cm 5 cm
The area of the shaded parallelogram is 20 square centimeters.
To find the area of the shaded parallelogram, we need to determine the base and height of the parallelogram. The base of the parallelogram is given by the length of one of its sides, and the height is the perpendicular distance between the base and the opposite side.
Looking at the diagram, we can see that the base of the parallelogram is the side measuring 4 cm. To find the height, we need to identify the perpendicular distance between the base and the opposite side.
In this case, the opposite side is the side of the rectangle measuring 10 cm, and we can see that the height of the parallelogram is equal to the side length of the rectangle that is not part of the parallelogram, which is 5 cm.
Now that we have the base and height, we can calculate the area of the parallelogram using the formula:
Area = base × height
Area = 4 cm × 5 cm
Area = 20 cm²
Therefore, the area of the shaded parallelogram is 20 square centimeters.

Step-by-step explanation:
that feels really so difficult to you ?
what is it you don't understand ? because this is really very easy. we take the input value as x and simply calculate the result.
1
f(x) = x³ - 5x² + 6x - 4
f(2) = 2³ - 5×2² + 6×2 - 4 = 8 - 20 + 12 - 4 = -4
2
f(x) = 4x³ + 3x² + x + 2
f(1) = 4×1³ + 3×1² + 1 + 2 = 4 + 3 + 1 + 2 = 10
3
f(x) = 2x⁴ - x³ + 3x² - 1
f(-1) = 2×(-1)⁴ - (-1)³ + 3×(-1)² - 1 = 2×1 + 1 + 3 - 1 = 5
4
f(x) = 2x³ - 6x - 5
f(-3) = 2×(-3)³ - 6×-3 - 5 = -54 + 18 - 5 = -41
5
f(x) = x³ - 4x² - x
f(4) = 4³ - 4×4² - 4 = (4³ - 4³) - 4 = -4
6
f(x) = x³ + 2x² - 2x - 1 divided by x -1 = x² + 3x + 1
- x³ - x²
-----------------------
0 + 3x² - 2x
- 3x² - 3x
---------------------------
0 + x - 1
- x - 1
--------------------------------
0 remainder, so, yes, x-1 is a factor.
7
f(x) = 4x² + 13x + 10 divided by x + 2 = 4x + 5
- 4x² + 8x
-----------------------
0 + 5x + 10
- 5x + 10
‐------------------------------
0 remainder, so x + 2 is a factor.
8
let's now try the factor theorem (the term is a factor if the zero point of the term is also a zero point of the whole function).
the zero point of x - 2 is x = 2.
f(x) = 4x² + 13x + 10
f(2) = 4×2² + 13×2 + 10 = 16 + 26 + 10 = 52 and not 0, therefore, x - 2 is NOT a factor.
9
the zero point of x + 3 is x = -3
f(x) = 3x³ + 10x² + x - 6
f(-3) = 3×(-3)³ + 10×(-3)² + (-3) - 6 = -81 + 90 - 3 - 6 = 0
so, x + 3 is a factor.
10
the zero point of x - 5 is x = 5.
so, f(5) must be 0 for x-5 to be a factor.
f(x) = 2x³ - 13x² + kx + 10
f(5) = 2×5³ - 13×5² + 5k + 10 = 250 - 325 + 5k + 10 =
= -65 + 5k
and that has to be 0.
0 = -65 + 5k
65 = 5k
k = 13
so, x-5 is a factor of 2x³ - 13x² + 13x + 10

a small shipping container is shaped like a right rectangular prism that is approximately 8ft tall, 8ft side, and 20 ft long. What is the length of a diagonal from a top corner to the opposite bottom corner? Round to the nearest hundredth.
Answer:
22.98
Step-by-step explanation:
The right triangle that contains the diagonal the problem asks for has legs c and e and a hypotenuse d. You will need another right triangle to find the value of e. Using the base of the container, you have a right triangle with legs a and b and a hypotenuse e. The container is 8 ft wide. This is the value of b. The container is 20 ft long. This is the value of a.
a2+b2=e2202+82=e2400+64=e2464=e2464−−−√=e2−−√±21.54≈e
The problem tells you that the container is 8 ft tall. This is the value of c. Now that you have e, you can solve for d.
c2+e2=d282+(21.54)2≈d264+464≈d2528≈d2528−−−√≈d2−−√±22.98≈d
The length of a diagonal from a top corner to the opposite bottom corner of the container is approximately equal to 22.98 ft. Remember that length cannot be negative.

I will say that to know if its rational, you have to see if the integer can be written in a fraction (like 0.333, 89/10, -4, 0)
Answer:
Whole numbers: 3, \(\sqrt{4}\), \(\frac{49}{7}\), zero
Integer but not whole: -100, -34, -4, -\(\frac{8}{4}\)
Rational number: 9.23456, \(\frac{1}{2}\), \(\frac{89}{10}\), 0.333_
Irrational number: \(\pi\), 0.456783_, \(\sqrt{8}\)
Step-by-step explanation:
Whole number is any number that does not have a decimal and is not negative. \(\sqrt{4}\) = 2. \(\frac{49}{7}\) = 7. 0 is not negative and does not have a decimal so it is also a whole number.
Integers are any number that does not have a decimal and can be both positive or negative. -\(\frac{8}{4}\) = -2.
A rational number can have a decimal but the decimal digits must terminate or the digit must repeat. \(\frac{1}{2}\) is 0.5. \(\frac{89}{10}\) is 8.9 and 0.333_ repeats the digit 3 so it is rational.
An irrational number can have a decimal and the decimal digits must list on forever or not repeat. \(\pi\) is naturally an irrational number as it does not repeat and it spreads on forever. 0.456783_ does not repeat and goes on forever due to the dash at the back. \(\sqrt{8}\) is also not rational.
The endpoints of one diagonal of a square are B (4,6) and A (9,17). What are the coordinates of the endpoints of OS, which is the other diagonal
The endpoints of the other diagonal are ((1/2) * (13 - √146), 11.5) and ((1/2) * (√146 + 13), 11.5).
Let's first find the length and midpoint of the diagonal with endpoints (4, 6) and (9, 17):
Length of diagonal = √[(9 - 4)² + (17 - 6)²] = √(5² + 11²) = √146
Midpoint of diagonal = [((4 + 9) / 2), ((6 + 17) / 2)] = (6.5, 11.5)
Now, we know that the other diagonal is parallel to the x-axis. Let's call the endpoints of this diagonal (a, b) and (c, b), where b is the y-coordinate of the midpoint of the first diagonal, which we just found as 11.5.
Since the rectangle is a right-angled shape, we know that the length of the diagonal with endpoints (a, b) and (c, b) is equal to the length of the diagonal with endpoints (4, 6) and (9, 17):
√[(c - a)² + (b - b)²] = √146
Simplifying this equation, we get:
√[(c - a)²] = √146
Taking the square of both sides, we get:
(c - a)² = 146
We also know that the midpoint of this diagonal is (6.5, 11.5). So we can write:
(a + c) / 2 = 6.5
Solving these two equations simultaneously, we get:
c - a = √146 ... (1)
a + c = 13 ... (2)
Adding equations (1) and (2), we get:
2c = √146 + 13
c = (1/2) * (√146 + 13)
Substituting this value of c in equation (2), we get:
a = 13 - c
a = (1/2) * (13 - √146)
Therefore, the endpoints of the other diagonal are ((1/2) * (13 - √146), 11.5) and ((1/2) * (√146 + 13), 11.5).

prove that:(1-tan⁴ A) cos⁴A =1-2sin²A
By following the steps outlined above and simplifying the equation, we have successfully proven that (1 - tan⁴A) cos⁴A = 1 - 2sin²A.
To prove the equation (1 - tan⁴A) cos⁴A = 1 - 2sin²A, we can start with the following steps:
Start with the Pythagorean identity: sin²A + cos²A = 1.
Divide both sides of the equation by cos²A to get: (sin²A / cos²A) + 1 = (1 / cos²A).
Rearrange the equation to obtain: tan²A + 1 = sec²A.
Square both sides of the equation: (tan²A + 1)² = (sec²A)².
Expand the left side of the equation: tan⁴A + 2tan²A + 1 = sec⁴A.
Rewrite sec⁴A as (1 + tan²A)² using the Pythagorean identity: tan⁴A + 2tan²A + 1 = (1 + tan²A)².
Rearrange the equation: (1 - tan⁴A) = (1 + tan²A)² - 2tan²A.
Factor the right side of the equation: (1 - tan⁴A) = (1 - 2tan²A + tan⁴A) - 2tan²A.
Simplify the equation: (1 - tan⁴A) = 1 - 4tan²A + tan⁴A.
Rearrange the equation: (1 - tan⁴A) - tan⁴A = 1 - 4tan²A.
Combine like terms: (1 - 2tan⁴A) = 1 - 4tan²A.
Substitute sin²A for 1 - cos²A in the right side of the equation: (1 - 2tan⁴A) = 1 - 4(1 - sin²A).
Simplify the right side of the equation: (1 - 2tan⁴A) = 1 - 4 + 4sin²A.
Combine like terms: (1 - 2tan⁴A) = -3 + 4sin²A.
Rearrange the equation: (1 - 2tan⁴A) + 3 = 4sin²A.
Simplify the left side of the equation: 4 - 2tan⁴A = 4sin²A.
Divide both sides of the equation by 4: 1 - 0.5tan⁴A = sin²A.
Finally, substitute 1 - 0.5tan⁴A with cos⁴A: cos⁴A = sin²A.
Hence, we have proven that (1 - tan⁴A) cos⁴A = 1 - 2sin²A.

In the given figure ABCD, prove that
angleBCD= angleBAD+ angle ABC+angle ADC.
[Hint: Join A and C then extended AC to the point E]
We have proved that Angle BCD is equal to angle BAD plus angle ABC plus angle ADC, as required.
To prove that angle BCD is equal to angle BAD plus angle ABC plus angle ADC, we can use the following steps:
Step 1: Join points A and C with a line segment. Let's label the point where AC intersects with line segment BD as point E.
Step 2: Since line segment AC is drawn, we can consider triangle ABC and triangle ADC separately.
Step 3: In triangle ABC, we have angle B + angle ABC + angle BCA = 180 degrees (due to the sum of angles in a triangle).
Step 4: In triangle ADC, we have angle D + angle ADC + angle CDA = 180 degrees.
Step 5: From steps 3 and 4, we can deduce that angle B + angle ABC + angle BCA + angle D + angle ADC + angle CDA = 360 degrees (by adding the equations from steps 3 and 4).
Step 6: Consider quadrilateral ABED. The sum of angles in a quadrilateral is 360 degrees.
Step 7: In quadrilateral ABED, we have angle BAD + angle ABC + angle BCD + angle CDA = 360 degrees.
Step 8: Comparing steps 5 and 7, we can conclude that angle B + angle BCD + angle D = angle BAD + angle ABC + angle ADC.
Step 9: Rearranging step 8, we get angle BCD = angle BAD + angle ABC + angle ADC.
Therefore, we have proved that angle BCD is equal to angle BAD plus angle ABC plus angle ADC, as required.

Given: Quadrilateral \(\displaystyle\sf ABCD\)
To prove: \(\displaystyle\sf \angle BCD = \angle BAD + \angle ABC + \angle ADC\)
Proof:
1. Draw segment \(\displaystyle\sf AC\) and extend it to point \(\displaystyle\sf E\).
2. Consider triangle \(\displaystyle\sf ACD\) and triangle \(\displaystyle\sf BCE\).
3. In triangle \(\displaystyle\sf ACD\):

Step-by-step explanation:
the sampling distribution of a single proportion is approximately normal if the number of success or the number of failures is greater than or equal to 10. (True or False)
The given statement, "The sampling distribution of a single proportion is approximately normal if the number of successes or the number of failures is greater than or equal to 10" is True.
The sampling distribution of a single proportion is approximately normal if the sample size is large enough and the number of successes or the number of failures is greater than or equal to 10. This is known as the normal approximation of the binomial distribution.
The normal approximation to the binomial distribution is based on the central limit theorem, which states that as the sample size increases, the sampling distribution of the sample means approaches a normal distribution, regardless of the shape of the population distribution. In the case of the binomial distribution, the sample mean is the proportion of successes, and as the sample size increases, the sampling distribution of the sample proportion approaches a normal distribution.
When the number of successes or the number of failures is less than 10, the normal approximation to the binomial distribution may not be valid, and alternative methods, such as the exact binomial distribution or the Poisson approximation, may need to be used.

company a rents copiers for a monthly charge of $200 plus 10 cents per copy. company b rents copiers for a monthly charge of $400 plus 5 cents per copy. what is the number of copies above which company a's charges are the higher of the two? write your answer as a number only.
Therefore, when the number of copies made in a month is above 4000, company A's charges are higher than company B's charges in the given equation.
Let's start by setting up an equation to represent the cost of renting a copier from each company:
Cost for company A = 0.10x + 200
Cost for company B = 0.05x + 400
where x is the number of copies made in a month.
To find the number of copies above which company A's charges are higher than company B's charges, we need to set the two equations equal to each other and solve for x:
0.10x + 200 = 0.05x + 400
0.05x = 200
x = 4000
