2) x2 - 12x + 38 = 6
square Strategy
Answers
Answer:
x = 4, x = 8
Step-by-step explanation:
Given the quadratic equation, x² - 12x + 38 = 6
Subtract 38 from both sides:
x² - 12x + 38 - 38 = 6 - 38
x² - 12x = -32
You'll need to rewrite the equation in the form, x² + 2ax + a². To find the value of a:
2ax = -12x
Divide both sides by 2x to solve for the value of a :
\(\frac{2ax}{2x} = \frac{-12x}{2x}\)
a = -6
Substitute the value of a into the quadratic form, x² + 2ax + a²
x² - 12x + a² = -32 + a²
x² - 12x + (-6)² = -32 + (-6)²
x² - 12x + 36 = -32 + 36
x² - 12x + 36 = 4
Rewrite the perfect square trinomial into its binomial factors:
x² - 12x + 36 = 4
(x - 6)² = 4
To solve for x, take the square root of each side of the inequality:
\(\sqrt{(x - 6)^{2}} = +/- \sqrt{4}\)
\(\sqrt{(x - 6)^{2}} = \sqrt{2^{2} } = (x - 6) = 2\)
(x - 6) = 2For (x - 6) = 2, start by adding 6 to both sides of the equation:
x - 6 + 6 = 2 + 6
x = 8
\(\sqrt{(x - 6)^{2}} = -\sqrt{2^{2} } = (x - 6) = -2\)
(x - 6) = -2For (x - 6) = - 2, start by adding 6 to both sides of the equation:
x - 6 + 6 = - 2 + 6
x = 4
Therefore, the solutions to the quadratic equations using the perfect square strategy are: x = 4, x = 8.

Answers
the correct choice is {0, 18}. These elements are unique to set C and do not appear in set A.
To find the set difference C - A, we need to remove all elements from A that are also present in C. Let's examine the sets:
C = {0, 6, 12, 18}
A = {2, 4, 6, 8, 10, 12}
We compare each element of A with the elements of C. If an element from A is found in C, we exclude it from the result. After the comparison, we find that the elements 2, 4, 8, 10 are not present in C.
Thus, the set difference C - A is {0, 18}, as these are the elements that remain in C after removing the common elements with A.
Therefore, the correct choice is {0, 18}. These elements are unique to set C and do not appear in set A.

If you need to produce an extra 10,000 units in a given week how many extra people will it require? Question: Each sandwich takes 10 minutes to make which means in the 10 hour shift there will be a... Each sandwich takes 10 minutes to make which means in the 10 hour shift there will be a total of 60 sandwiches. The deli wants an efficient way to increase the sandwich output using the same five workers and 10 hour shift (Don't Factor Break in) to produce 75 because of the 25% increase due to the expansion of the deli. What would you do to make the the process more efficient? Where each sandwich would take 8 minutes to make instead of 10 minutes. Please answer the question throughly.
Answers
Extra people required is 50.
Each of the five workers should increase their efficiency to a rate of 15 sandwiches per 10 hour shift.
What is Proportion?Proportions are defined as the concept where two or more ratios are set to be equal to each other.
Question 1 :
Number of associates = 30
Number of direct workers = 30 - 2 = 28
You work 8 hours a day and 5 days a week with two 15 minutes break or 30 minutes break per day.
Direct rate = 150 units per hour
Number of working hours in a week with break = 8 × 5 = 40 hours per week Number of working hours in a week = 7.5 hours per day × 5 days a week
= 37.5 hours per week
Units that department produce in a 40 hour week = 37.5 × 150 = 5625 units
28 people produce 5625 units in a week
Let x people produce 10,000 + 5625 = 15,625 units in a week
Using proportion,
28 : 5625 = x : 15,625
28 / 5625 = x / 15,625
x = (28 × 15,625) / 5625 = 77.78 ≈ 78
Extra people required = 78 - 28 = 50
Question 2 :
Number of sandwiches made in 10 minutes = 1
Number of sandwiches made in 10 hours = 60
5 workers are there. one worker makes 60/5 = 12 sandwiches
But Deli want number of sandwiches in 10 hours = 75
One worker should make 75/5 = 15 sandwiches instead of 12.
Number of sandwiches made in 8 minutes should be 1.
So the working efficiency on each worker should be increased and produce each one should produce 15 sandwiches in a 10 hour shift.
Hence extra people required in question 1 is 50 and efficiency of each worker in question 2 should be increased to 15 sandwiches in 10 hours shift.

Find the number of possible outcomes for following situation.
A rectangle has a perimeter of 12 and integer side lengths.
Answers
To find the number of possible outcomes for a rectangle with a perimeter of 12 and integer side lengths, we can consider the different combinations of side lengths that satisfy the given conditions.
Let's denote the length and width of the rectangle as L and W, respectively. The perimeter of a rectangle is given by the formula P = 2L + 2W. In this case, we have P = 12. Substituting the values into the formula, we get 2L + 2W = 12. Simplifying further, we have L + W = 6. Now, we can explore the possible integer solutions for L and W that satisfy the equation L + W = 6. These solutions include (1, 5), (2, 4), and (3, 3). The side lengths of the rectangle are interchangeable, so (1, 5) is equivalent to (5, 1), and (2, 4) is equivalent to (4, 2). Therefore, there are three possible outcomes for the side lengths of the rectangle that satisfy the given conditions.

Let C be the curve which is the union of two line segments, the first going from (0, 0) to (4, -3) and the second going from (4, -3) to (8, 0). Compute the line integral So 4dy + 3dx. A 5-2
Answers
To compute the line integral ∮C 4dy + 3dx, where C is the curve consisting of two line segments, we need to evaluate the integral along each segment separately and then sum the results.
The first line segment goes from (0, 0) to (4, -3), and the second line segment goes from (4, -3) to (8, 0).
Along the first line segment, we can parameterize the curve as x = t and y = -3/4t, where t ranges from 0 to 4. Computing the differential dx = dt and dy = -3/4dt, we substitute these values into the integral:
∫[0, 4] (4(-3/4dt) + 3dt)
Simplifying the integral, we get:
∫[0, 4] (-3dt + 3dt) = ∫[0, 4] 0 = 0
Along the second line segment, we can parameterize the curve as x = 4 + t and y = 3/4t, where t ranges from 0 to 4. Computing the differentials dx = dt and dy = 3/4dt, we substitute these values into the integral:
∫[0, 4] (4(3/4dt) + 3dt)
Simplifying the integral, we get:
∫[0, 4] (3dt + 3dt) = ∫[0, 4] 6dt = 6t ∣[0, 4] = 6(4) - 6(0) = 24
Finally, we sum up the results from both line segments:
Line integral = 0 + 24 = 24
Therefore, the value of the line integral ∮C 4dy + 3dx is 24.

A cone is a three-dimensional shape that has a circular base with tapers from the flat base into the vertex.
The formula for searching the volume of the cone can be described below :
V = \(\frac{1}{3}\) π \(r^{2}\) h
which
V = volume of the cone
r = radius of cone circular base
h = height of cone ( tall of the cone )
From the question, we have following information :\
1. Base diameter = 32 feet
Base radius = Base diameter / 2 = 32 feet / 2 = 16 feet
2. Tall / Height of the cone = 14 feet
Since the known parameter is enough to be put into the formula, we can simply subtitute the formula with known parameter
V = \(\frac{1}{3}\) π \(r^{2}\) h

Here, the rectangle is inscribed inside the circle.
The rectangle has dimensions of 5 cm by 11 cm, and the circle has a radius of 12 cm.
To solve for any other information, we can use some geometry formulas.
First, we can find the diagonal of the rectangle using the Pythagorean theorem:
diagonal^2 = 5^2 + 11^2
diagonal = sqrt(5^2 + 11^2) ≈ 12.083 cm
Since the diagonal of the rectangle is the diameter of the circle, we know that the circle's diameter is approximately 12.083 cm.
