In right triangle PQR, P and Q are complementary angles. The value of sin Q is 9/41. What is the value of cos P?
Final answer:
In right triangle PQR, sin Q = 9/41. To find cos P, we need to determine the length of the hypotenuse PR. Once we have PR, we can use the cosine function to find cos P.
Explanation:
In a right triangle, the sine of an angle is the length of the side opposite the angle divided by the length of the hypotenuse. So, in triangle PQR, sin Q = opposite/hypotenuse = PQ/PR = 9/41.
Since angles P and Q are complementary, their sum is 90 degrees. Therefore, angle P = 90 - angle Q.
Now, using the Pythagorean theorem for triangle PQR (PQ^2 + QR^2 = PR^2), we can find PR. Since PQ = 9 and QR = 41, we have: 9^2 + 41^2 = PR^2. Solving for PR gives us PR ≈ 41.297.
Now that we have PR, we can find cos P using the cosine function: cos P = adjacent/hypotenuse = QR/PR = 41/41.297 ≈ 0.993.
In a right triangle, sin Q = 9/41. To find cos P, we can use the identity cos(90 - x) = sin(x). So cos P = sin(Q) = 9/41.
Explanation:In a right triangle, the sine of an angle is equal to the length of the side opposite the angle divided by the hypotenuse. In this case, sin Q = 9/41, which means that the length of the side opposite Q is 9 and the length of the hypotenuse is 41. Since P and Q are complementary angles, P = 90 - Q. Therefore, cos P = cos(90 - Q).
Using the identity cos(90 - x) = sin(x), we can substitute the value of Q to find cos P. cos P = sin(Q) = 9/41.

Step-by-step explanation:
Write and solve an equation to answer the question. "18 is 32% of what number w"
The value of 32% of 18 is equal to 56.25.
The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that 18 is 32% of the number w. The value of w will be calculated as:-
18 x 32/100 = w
Solve the above equation by mathematical operations to get the value of w,
18 x 32/100 = w
w = 56.25
Therefore, the value of w will be 56.25.

The ratio of girls to boys in a classroom is 3:5. Kevin says there must be 8 students in the classroom. Which explains whether Kevin is correct?
Kevin is incorrect because 3:5 may be a simplified ratio.
Kevin is incorrect because 3:5 may be a simplified ratio. Option C is correct.
Given that,
The ratio of girls to boys in a classroom is 3:5. Kevin says there must be 8 students in the classroom. Which explains whether Kevin is correct is to be determined,
The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
Here, the ratio of girls to boys is 3:5, Which implies there are 3 girls over 5 boys in the number, This is the simplified ratio of the girls to boys of the students in the class. So, Kevin says there must be 8 students in the classroom which is right, but Kevin does not explain the proportion in his statement,
Thus, Kevin is incorrect because 3:5 may be a simplified ratio. Option C is correct.

laissez faire is the term used to describe a capitalist economy without any regulations
Information about Laissez-faire's economy is given.
What is a Laissez-faire economy?Laissez-faire is a free-market, capitalist economic theory that rejects government interference. The French Physiocrats, who lived in the 18th century, created the laissez-faire ideology. According to proponents of laissez-faire, government involvement in industry and markets hinders economic progress.
Laissez-Faire capitalism allowed businesses to pursue just their financial goals without having to worry about restrictions from the state or taxes. Naturally, this might induce unfavorable externalities and knowledge asymmetries that could enable producers to act badly and get away with it. Laissez-Faire proponents contend that since the market would eliminate such undesirable actors, extensive and expensive regulation is not necessary. However, in practice, negative actors might carry on their operations for a very long time. Without government testing and regulatory oversight to safeguard consumers, for instance, it could not be known if a vitamin manufacturer is putting sawdust in place of herb powder in their capsules.
Therefore, In real world the laissez-faire is a capitalist economy have regulations.

Write an equation of the line with a slope of 2 that passes through the point (2,0)
Hence, the line with a slope [tex]2[/tex] that passes through the point [tex](2,0)[/tex] is
[tex]y=2x-4[/tex]
What is the line of equation?
The equation of a line is an algebraic form of representing the set of points, which together form a line in a coordinate system.
The numerous points which together form a line in the coordinate axis are represented as a set of variables [tex]x, y[/tex] to form an algebraic equation, which is referred to as an equation of a line.
As we know the line of the slope is
[tex]y=mx+b[/tex]
where [tex]m[/tex] is the slope we have [tex]m = 2.[/tex]
So it would be
[tex]y=2x+b[/tex]
Given the point, [tex](2, 0)[/tex]
Now, we replace [tex]x[/tex] with [tex]2[/tex] and [tex]y[/tex] with [tex]0[/tex].
Now, we solve for [tex]b[/tex].
So,
[tex]0=2(2)+b\\b+4=0\\b=-4[/tex]
Since we get [tex]b = -4[/tex], we replace [tex]b = -4[/tex]
