To answer this question we need to remember that:
[tex]\sec \theta=\frac{1}{\cos \theta}[/tex]then:
[tex]\begin{gathered} \sec \theta=-\frac{13}{5} \\ \frac{1}{\cos \theta}=-\frac{13}{5} \\ \cos \theta=-\frac{5}{13} \\ \theta=\cos ^{-1}(-\frac{5}{13}) \\ \theta=112.62 \end{gathered}[/tex]There's only one angle that gives this result that it is real. Therefore the answer is 112.62
write an equation of the line that passes the through point (0, 9) and has slope m=2/3
An equation of the line that passes the through point (0, 9) and has slope m = [tex]\frac{2}{3}[/tex] is 3y-2x-27=0
What is point-slop equation of a line?
The point-slope equation of a line is
y - [tex]y_{1}[/tex] = m ( x -[tex]x_{1}[/tex] )
The equation is useful when we know:
one point on the line: ( [tex]x_{1}[/tex],[tex]y_{1}[/tex]) andthe slope of the line: m,and want to find other points on the line.
Given that,
slope , m = [tex]\frac{2}{3}[/tex] and passing through the point is (0,9)
An equation of a line given the slope and a point is
y - [tex]y_{1}[/tex] = m ( x -[tex]x_{1}[/tex] )
or y - 9 = [tex]\frac{2}{3}[/tex] (x - 0)
or y - 9 = [tex]\frac{2}{3}[/tex] x
or y = [tex]\frac{2}{3}[/tex] x + 9
or y = [tex]\frac{2x + 27}{3}[/tex]
or 3y = 2x + 27
or 3y - 2x - 27 = 0
Hence, an equation of the line that passes the through point (0, 9) and has slope m = [tex]\frac{2}{3}[/tex] is 3y-2x-27=0

_______ angles are used to relate the values returned by inverse trigonometric functions to angles larger than 90°.
A. Obtuse
B. Acute
C. Right
D. Complementary
Answer:
Acute
Step-by-step explanation:
Obtuse angles are angles that are larger than 90 but less than 180
Acute angles are angles that are less than 90 degrees
Right angles are angles that is exactly 90 degrees
Complementary angles are two angles whose sum is 90 degrees
Using this info, it seems the answer to this question is B. Acute because it says "the values returned by inverse to angles larger than 90" and since acute is the opposite of obtuse imma say B but im not too sure
help me!!! Write an equation of the line passing through the point (2, 8) that is perpendicular to the line 2x - 3y = 7
Answer:
y = -3/2x +11
Step-by-step explanation:
First you have to change the equation from standard form to slope form.
y = mx + b
2x-3y=7 --> subtract 2x from both sides
-3y = -2x + 7 --> now divide both sides by -3 to get y by itself
y = 2/3x - 7/3 --> the reason 2/3x is positive is because when there are two negatives it turns to a positive.
now you have to use point slope form y - y1 = m (x - x1)
x1 and y1 would be your point. 2 is x1 and 8 is y1
y - 8 = -3/2 (x - 2) --> the reason that m is -3/2 is because a perpendicular equation is the opposite reciprocal of the original slope
next distribute the -3/2
y-8 = -3/2x + 3 --> and now add 8 to 3 to get why by it self
now you have y = -3/2x + 11
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.

Answer:
(f/g)(x) = 4x^3 +x^2 -5x +10(f/g)(1) = 10Step-by-step explanation:
You want to find the rational function (f/g)(x) and its value for x=1 when f(x) = 4x^4−19x^3−10x^2+35x−50 and g(x) = x-5.
Polynomial divisionThe ratio function is the ratio of the given functions, found by dividing f(x) by g(x). Since g(x) is a binomial with a leading coefficient of 1, synthetic division is recommended. The attachment shows the result.
[tex](f/g)(x)=\dfrac{f(x)}{g(x)}=\dfrac{4x^4-19x^3-10x^2+35x-50}{x-5}\\\\\boxed{(f/g)(x)=4x^3+x^2-5x+10}[/tex]
The value of this function when x=1 is ...

The exponent of a number indicates how many times a number has been multiplied by itself. For instance, 3^4 indicates that we have multiplied 3 four times. Its full form is 3 3 3 3. Exponent is another name for a number's power. It could be an integer, a fraction, a negative integer, or a decimal. Exponents are necessary since, without them, it is highly challenging to express the product when a number is repeated several times by itself. For instance, it is much simpler to write 5^7 than it is to write 5 5 5 5 5 5.

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.

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.
