Evaluate the integral.
[tex]\pi\int\limits^{\frac{3\pi}{4}}_{\frac{\pi}{6}} {sin^4x+4sin^2x} \, dx[/tex]
By using trigonometric formulas and integration rules, we conclude that the integral is approximately equal to - 7.764 units.
How to determine the value of a definite integral
In this problem we must determine the solution to a definite integral of trigonometric equations, which requires the use of trigonometric formula and integration rules to be found. The integral can be simplified by using the following formulas:
sin⁴ x = (1 / 8) · (3 - 4 · cos 2x + cos 4x)
sin² x = (1 /2) · (1 - cos 2x)
Then, the integral is simplified into this form:
[tex]I = \pi \int \limits_{\frac {\pi}{6}}^{\frac{3\pi}{4}} \sin^{4} x \,dx + 4\pi \int \limits_{\frac {\pi}{6}}^{\frac{3\pi}{4}} \sin^{2} x \,dx[/tex]
[tex]I = \frac{\pi}{8} \int \limits_{\frac {\pi}{6}}^{\frac{3\pi}{4}} (3 - 4\cdot \cos 2x + \cos 4x) \,dx + 4\pi \int \limits_{\frac {\pi}{6}}^{\frac{3\pi}{4}} (1 - \cos 2x) \,dx[/tex]
[tex]I = \frac{3\pi}{8}\cdot x - \frac{\pi}{4} \cdot \sin 2x + \frac {\pi}{32}\cdot \sin 4x - 4\pi \cdot x - 2\pi\cdot \sin 2x[/tex], for x ∈ [π / 6, 3π / 4]
And the definite integral is:
I = 2.159 + 1.466 - 0.085 - 23.028 + 11.724
I = - 7.764
The definite integral of f(x) = sin⁴ x + 4 · sin² x for x ∈ [π / 6, 3π / 4] is approximately equal to - 7.764.

Answer: [tex]-4 < m \le -3[/tex]
=========================================================
Reason:
If m = -4, then f(x) = m becomes f(x) = -4. This yields the single solution x = -4
How do we get this solution? Start at -4 on the y axis. Move horizontally until reaching the curve. You should arrive at (-4,-4) which is the lowest point of this curve. Then move upward until reaching the x axis to arrive at x = -4
All of this says that the input x = -4 leads to the output y = f(x) = -4
---------------
We've gone over m = -4 leading to one solution, so that's out of the question since we want two solutions.
But if m = -3 for instance, then notice how tracing a horizontal line to the curve arrives at two locations instead of one. We arrive at x = -2 and x = -5 as the solutions to f(x) = -3
All of these solutions mentioned are negative which fits the criteria we're after. If m is in the interval from -4 to -3, excluding -4 but including -3, then we'll have f(x) = m with two negative solutions for x.
What is the slope of the line perpendicular to the line represented by the equation 2x+2y=-12
The slope of the line perpendicular to the line given by equation 2x+2y=-12 is found as 1.
What is the definition of line slope?The slope of a line measures its steepness as well as direction.The slope of a line is defined as the change throughout y coordinate in relation to the transitions in x coordinate.The net change in y coordinates is Δy, while the net change in x coordinates is Δx.So m represents the change in y coordinate in relation to a shift in x coordinate.The slope can be calculated using the following formula:
m = Δy/Δx
Where, m is the slope.
The equation of the line is; 2x+2y=-12
Write the equation in slope-intercept form.
2x + 2y = -12
Divide by 2.
x + y = -6
y = -x - 6
Slope m₁ = -1 and y-intercept = -6.
As, both line are perpendicular.
Thus,
m₁ x m₂ = -1
m₂ = -1/m₁
Put the value.
m₂ = -1/(-1)
m₂ = 1
The slope of the perpendicular line is found as 1.

When three of these twelve aircraft are selected at random, the probability that all three of them will be F/A-18E's is 0.018.
How to calculate the probability?Based on the information given, there are are 12 F/A-18 aircraft, where: 3 are F/A-18A's 4 are F/A-18E's 5 are F/A-18F's. The total number of aircraft will be 12.
When three of these twelve aircraft are selected at random, so that every possible selection is equally likely, the probability that all three of them will be F/A-18E's will be:
= 4/12 × 3/11 × 2/10
It should be noted that this is without replacement that's why we have 10, 11 and 12 as the denominator.

An airport in a country that has an elevated occurance of terrorism profiles airline passengers and semi-randomly selects who will undergo additional screening. If one person is stoped, everyone they are traveling with is also stopped. Over the course of several months, the airport security stops 15% of passengers for this extra screening. On a certain day, 519 passengers go through security at this airport. Let the variable be the number of those people who are chosen for additional screening.
Is the number of passengers who are chosen for additional screening a binomial random variable? Select all that apply.
Yes. All four conditions are met.
No. There is not a fixed number of trials.
No. The trials cannot reasonably be assumed to be independent.
No. The outcomes cannot be described as only "success" and "failure."
No. The probability of success is not the same for each trial.
No. there is not a fixed number of trials. The correct option is B.
What is a binomial random variable?A variable with only two outcomes is said to be binary. Examples of binary categorical variables are sex (male/female) and having a tattoo (yes/no).
Each trial must be independent, meaning that it must have a defined number of trials and a constant success rate. Its probability needs to range from 0 to 1.
There are only two conceivable outcomes for each individual. They are either filtered or they are not. We are not interested in learning how many people were screened, though.
It is an inverse binomial, we want to know how many persons will be screened before 10, which is a binomial. Therefore, since there are an arbitrary number of trials, this is not a binomial equation, and option B provides the solution.
Therefore, there is not a fixed number of trials. The correct option is B.

The point (-13, 24) is on the graph of y = f(x). Find the corresponding point on the graph of y= g(x), where g(x) = 1/4f(x)
Answer:
(−12,2)
Step-by-step explanation:
1:
Dividing the function by 2 divides all the y-values by 2 as well. So to get the new point, we will take the y-value
(4) and divide it by 2 to get 2
.
Therefore, the new point is
(−12,2)
2:
Subtracting 2 from the input of the function makes all of the x-values increase by 2 (in order to compensate for the subtraction). We will need to add 2 to the x-value
(−12) to get −10
.
Therefore, the new point is
(-10,4)
3:
Making the input of the function negative will multiply every x-value by
−
1
. To get the new point, we will take the x-value
(−12) and multiply it by −1 to get 12.
Therefore, the new point is
(12,4)
4:
Multiplying the input of the function by 4 makes all of the x-values be divided by 4 (in order to compensate for the multiplication). We will need to divide the x-value
(−12) by 4 to get −3
.
Therefore, the new point is
(−3,4)
5:
Multiplying the whole function by
4
increases all y-values by a factor of
4
, so the new y-value will be
4
times the original value
(4), or 16.
Therefore, the new point is
(−12,16)
6:
Multiplying the whole function by
−1
also multiplies every y-value by
−1
, so the new y-value will be
−1
times the original value
(4), or −4.
Therefore, the new point is
(−12,−4)

What is a periodic withdrawal of a sum lump?A periodic withdrawal is the opposite of a periodic payment.
In a periodic withdrawal, the investor withdraws a constant amount from the investment that earns interest until it is exhausted.
A periodic withdrawal is the same as a payout annuity, which involves periodic receipts from the invested capital.
Using an online finance calculator, we can compute the quarterly withdrawals as follows:
N (# of periods) = 12 quarters (3 x 4)
I/Y (Interest per year) = 6%
PV (Present Value) = $20,000
FV (Future Value) = $0
Results:
Withdrawals = $-1,833.60
Sum of all periodic payments = $-22,003.20

What is reasoning ?Thinking and cognition are related to reasoning, which requires using one's intellect. The study of logic focuses on how people can construct logically sound arguments using formal reasoning. Deductive, inductive, and abductive reasoning are three examples of logical reasoning that can be used to further break down reasoning. Aristotle distinguished between logical discursive reasoning (reason proper) and intuitive reasoning, noting that the former may lean toward the subjective and the personal, despite being correct. While logical and intuitive styles of reasoning might clash in certain social and political circumstances, in others they are considered as complimentary rather than competitive.
