If a firm uses x units of input in process A, it produces 32x3/2 units of output. In the alternative process B, the same input produces 4x3 units of output. For what levels of input does process A produce more than process B?
Answers
Answer:
The outcomes produced by A would be greater than B. A further explanation is provided below.
Step-by-step explanation:
Given:
In process A,
Produced units = [tex]32x^{1.5}[/tex]
In process B,
Produced units = [tex]4x^3[/tex]
If the outcomes are equivalent then,
⇒ [tex]32x^{1.5}=4x^3[/tex]
⇒ [tex]x^{1.5} = 8[/tex]
By taking log both sides, we get
⇒ [tex]log \ 8= 1.5 \ log \ x[/tex]
⇒ [tex]x=3.99[/tex]
Are holidays a proper subset of the calendar year?
Select the correct answer below:
No, holidays are only a subset of the calendar year.
Yes, holidays are a proper subset but not a subset of the calendar year.
Yes, holidays are a subset and proper subset of the calendar year.
No, holidays are not a subset or proper subset of the calendar year.
Answers
Answer: Choice C
Yes, holidays are a subset and proper subset of the calendar year.
=========================================================
Explanation:
The set of days in the calendar year spans from Jan 1st to Dec 31st.
The set of holidays is a small subset of the previous set mentioned. Any holiday is found on the calendar, but not every day on the calendar is a holiday.
------------
Here's another example of a subset
A = set of all animals
B = set of dogs
Set B is a subset of set A because any dog is an animal. In other words, any individual in set B is also in set A, but not the other way around.
------------
Going back to the calendar example, the set of holidays is a subset and it's also a proper subset of all the days in the year. We say that set B is a proper subset of set A if B has less items in it compared to A.
If we had these two sets
A = {1,2,3,4,5,6}
B = {1,2,3}
We can see that B is a proper subset of set A since everything in B is found in A, and B is smaller than A. The only time we have a subset and not a proper subset is when we talk about the set itself. Any set is a subset of itself (not a proper subset of itself).
The True statement is
Yes, holidays are a subset and proper subset of the calendar year.
What is Set?Sets are represented as a collection of well-defined objects or elements that are consistent from one person to the next. A capital letter represents a set. The cardinal number of a set is the number of items in a finite set.
The order of a set determines the number of elements in the set. It refers to the size of a set. The order of the set is often referred to as the cardinality.
The set of days in the calendar year spans from Jan 1st to Dec 31st.
The set of holidays is a subset of the previously described set. Any holiday can be found on the calendar, however not every day is a holiday.
let Set B is a Proper subset of set A if it contains fewer elements than A.
So, A = {1,2,3,4,5,6}
B = {1,2,3}
We can see that B is a proper subset of set A since everything in B is found in A, and B is smaller than A.
So, holidays are a subset and proper subset of the calendar year.

You can identify sample spaces for compound events using organized lists, tables, and tree diagrams. Which of the three methods do you find easiest to use? Which method is the most helpful? Why? Use the Internet or another resource to find the definition of the Fundamental Counting Principle. What does this principle state? How can the principle be used to help you identify a sample space for a compound event? What are the limitations of using the Fundamental Counting Principle when determining the probability of an outcome? Support your answers with an example.
Answers
The fundamental counting principle is used to count the total number of possible outcomes that are in a situation.
What does the fundamental counting principle state?The fundamental counting principle states that if there are n ways of doing something, as well as m ways of doing another thing, then there are n×m ways to perform both of these actions.
The Fundamental Counting Principle helps when determining the sample space of probability as it figures out the total number of ways the combination of events can occur. Therefore, it is used as a guide when determining the sample space of a probability.
Lastly, the limitation is that the Fundamental Counting Principle is that it assumes that each basic event is equally probable, which does not necessarily have to be true.

Sum of two digit number is9.When we interchange the digits it is found that the resulting new number becomes twice the other number. What are the numbers
Answers
Answer:
4 and 5
Step-by-step explanation:
Let the numbers be x and y
If their sum is 9, hence;
x + y = 9 ....1
When reversed
10y+x = 2(10x+y)
10y+x = 20x + 2y
10y - 2y = 20x - x
8y = 19x
y = 10x/8 ...2
Substitute equation 2 into 1;
From 1;
x+y = 9
x +(10x/8) = 9
18x/8 = 9
18x = 72
x = 72/18
x = 4
Since x+y =9
y = 9-x
y =9-4
y = 5
Hence the numbers are 4 and 5

Sara can weed a garden in 30 minutes. When her brother Hamdan helps her, they can weed the same garden in 20 minutes. How long would it take Hamdan to weed the garden if he
worked by himself?
a. Write an expression for Hamdan's rate, using n for the number of hours he would take to
weed the garden by himself.
b. Write an equation to show the amount of work completed when they work together.
c. How long would it take Hamdan to weed the garden by himself?
Answers
Answer:
Let's define:
S as the rate at which Sara can weed a garden.
We know that:
S*30min = 1 garden
And let's define H as the rate at which Hamdan can weed a garden, we know that when they work together, they can complete the job in 20 minutes, then
(S + H)*20min = 1 garden
a) Here we get:
H*n = 1 garden
where n is the number of hours that he would take (note that in two previous equations we have minutes, so we need to use a change of units)
b) The equation is
(S + H)*20min = 1 garden
c) ok, we know two things:
(S + H)*20min = 1 garden
S*30min = 1 garden
first, let's convert both times to hours:
60 min = 1 hour
then:
30 min = (30/60) hours = 0.5 hours
20 min = (20/60) hours = 0.33 hours
Then the equations become:
(S + H)*0.33 hours = 1 garden
S*0.5 hours = 1 garden
Le's solve the second equation for S:
S = (1 garden /0,5 hours) = 2 gardens/hour.
Now we can replace this in the other equation to get:
(2 garden/hour + H)*0.33 hours = 1 garden
2 garden/hour + H = (1 garden)/(0.33 hours) = 3 gardens/ hour
H = 3 gardens/hour - 2 gardens/hour = 1 gardens/hour
This means that the rate of Hamdan is 1 gardens/hour, so he can weed a garden in one hour.
Then:
(1 garden/hour)*n = 1 garden
n = ( 1 garden)/((1 garden/hour)) = 1 hour

21. Glass Vase You are taking a glass-blowing class and have created a vase in the

and it will sit on a stand. The radius of your vase is 21 inches. Use the formula

V
Answers
Answer:
V = 12,348·π
Step-by-step explanation:
The given parameters of the glass Vase are;
The shape of the glass vase = A sphere
The radius of the vase, r = 21 inches
The given formula for finding the volume of a sphere is [tex]V = \dfrac{4}{3} \cdot \pi \cdot r^3[/tex]
Therefore, when r = 21 inches, we get;
[tex]V = \dfrac{4}{3} \cdot \pi \cdot 21^3 = {12,348 \cdot \pi}[/tex]
Therefore, the expression for finding the equation of the spherical glass vase, V = 12,348·π

Determine the coordinates of this point of contact of the two graphs.
Answers
Answer:
[tex](1,\, 10)[/tex].
Step-by-step explanation:
Differentiate each function to find an expression for its gradient (slope of the tangent line) with respect to [tex]x[/tex]. Make use of the power rule to find the following:
[tex]g^\prime(x) = 3\, x^2 - 2\, a\, x[/tex].
[tex]h^\prime(x) = 2\, (2\, x) + b = 4\, x + b[/tex].
The question states that the graphs of [tex]g(x)[/tex] and [tex]h(x)[/tex] touch at [tex]x = 1[/tex], such that [tex]g^\prime(1) = h^\prime(1)[/tex]. Therefore:
[tex]3 - 2\, a = 4 + b[/tex].
On the other hand, since the graph of [tex]g(x)[/tex] and [tex]h(x)[/tex] coincide at [tex]x = 1[/tex], [tex]g(1) = h(1)[/tex] (otherwise, the two graphs would not even touch at that point.) Therefore:
[tex]1 - a + 6 = 2 + b + 3[/tex].
Solve this system of two equations for [tex]a[/tex] and [tex]b[/tex]:
[tex]\begin{aligned}& a + b = 2 \\ & 2\, a + b = -1\end{aligned}[/tex].
Therefore, [tex]a = -3[/tex] whereas [tex]b = 5[/tex].
Substitute these two values back into the expression for [tex]g(x)[/tex] and [tex]h(x)[/tex]:
[tex]g(x) = x^3 + 3\, x^2 + 6[/tex].
[tex]h(x) = 2\, x^2 + 5\, x + 3[/tex].
Evaluate either expression at [tex]x = 1[/tex] to find the [tex]y[/tex]-coordinate of the intersection. For example, [tex]g(1) = 1 + 3 + 6 = 10[/tex]. Similarly, [tex]h(1) = 2 + 5 + 3 = 10[/tex].
Therefore, the intersection of these two graphs would be at [tex](1,\, 10)[/tex].
