¿cuál de los siguientes valores de funciones es negativo? a. Sen 120° b. Sen 150° c. Cos 235° d. Cos 300°.
A function of the form \(f(x) = x^{-n}\), wherein n is a natural number, is regarded as a negative power function. Inside the form, we might also put \(f(x)\),that is\(f(x) = \frac{1}{x^n}\),and the further calculation can be defied as follows:
Given:
\(\bold{a)\ \sin 120^{\circ}}\\\\\bold{b)\ \sin 150^{\circ}}\\\\\bold{c)\ \cos 235^{\circ}}\\\\\bold{d)\ \cos 300^{\circ}}\\\\\)
To find:
Find negative function values =?
Solution:
\(\therefore \\\\\to \bold{\sin (180- \theta)= \sin \theta} \\\\\to \bold{\cos (180- \theta)= -\cos \theta} \\\\\to \bold{\cos (180+ \theta)= -\cos \theta} \\\\ \to \bold{\cos (360- \theta)= \cos \theta}\)
Solve value for a:
\(\to \bold{\sin 120^{\circ}= \sin(180-60)}\)
\(\bold{=\sin 60^{\circ}}\\\\\bold{=\frac{\sqrt{3}}{2}}\\\\\)
Solve value for b:
\(\to \bold{\sin 150^{\circ}= \sin(180-30)}\)
\(\bold{=\sin 30^{\circ}}\\\\\bold{=\frac{1}{2}}\\\\\)
Solve value for c:
\(\to \bold{\cos 235^{\circ}=-\cos( 180+55)}\)
\(\bold{=- \cos 55^{\circ}}\\\\\bold{= -0.57357643635}}\\\\\)
Solve value for d:
\(\to \bold{\cos 300^{\circ}= \cos(360-60)}\)
\(\bold{= \cos 60^{\circ}}\\\\\bold{= \frac{1}{2}}\\\\\)
Therefore, the final answer is "Option C".

Calculate the magnitude of the total resultant force f⃗ r=f⃗ 1+f⃗ 2+f⃗ 3 acting on the mass
Resultant will be (0.54î - 1.75j) N, Magnitude is 1.83 N, and the Direction is - 72.9°, as per the given equation.
What is resultant force?A resultant force is the single force and corresponding torque that are produced when adding vectors to a system of forces and torques acting on a rigid body.
From the free body diagram, the resultant is a vector sum of all the three individual forces.
F₁ = 4(cos 25°î + sin 25°j) = (3.625î + 1.691j) N
F₂ = 6(cos 325î + sin 325j) = (4.915î - 3.441j) N
F₃ = (- 8î) N
Resultant force is
F₁ + F₂ + F₃ = (3.625î + 1.691j) + (4.915î - 3.441j) + (- 8î) = (0.54î - 1.75j) N
Magnitude = √[(0.54²) + (-1.75²)] = 1.83 N
Direction = tan⁻¹ (-1.75/0.54) = - 72.9°
Thus, this is the the magnitude of the total resultant force.

In the united states, a woman's shoe size of fits feet that are centimeters long. What percentage of women in the united states will wear a size or smaller?.
The percentage of women in the united states will wear a size 6 fits or smaller is 22.07%.
Z scoreThe z score is used to determine by how many standard deviations, the raw score is above or below the mean. It is given by:
z = (x - μ)/σ

μ = 23.4, σ = 1.3, x = 6 fits = 22.4, hence:
For x < 22.4:
z = (22.4 - 23.4)/1.3 = -0.77

Use this sentence: On a summer day, the heat of the land heats the air, causing it to rise and spread before cooling over the ocean, creating a
breeze.
How is thermal energy transferred when this happens?
(1 point)
through radiation
Othrough refraction
through convection
O through conduction
Thermal energy may be transferred from one place to another in solids, liquids, or gases by conduction, convection, or radiation. Convection allows heat to be transferred from water to air and then distributed throughout the ocean. (Option C)
What is Convection?Convection currents are formed by radioactive decay in the core when heat rises and falls inside the mantle. The plates are moved by convection currents. Plates migrate apart where convection currents separate near the Earth's crust. Plates migrate towards each other when convection currents converge.
Temperature gradients form a specific fluid, the difference in densities of which causes convection currents. This suggests that convection currents play an important part in fluid circulation.
These currents aid in the transport of heat from one location to another by utilizing the mass motion of a specific fluid such as water, air, or even molten rock.
This heat transfer function of convection currents contributes to the Earth's ocean currents, atmospheric weather, and general geology. Convection currents in the Earth's mantle are considered to be the driving force behind the tectonic plates.

Answer: 1/6
Explanation:
The question is asking how much of the whole circumference is arc AB given that it's central angle is 60°. We can see that the angle is \(\frac{60}{360}\) of the whole. This means that if there were 360 equal sectors, or slices, of the circle, then this angle would take 60 of them.
From this, we can see that if the circumference was divided into 360 equal parts, then the arc would also take up 60 of them, making the arc \(\frac{60}{360}\), or \(\frac{1}{6}\).
We could have alternatively seen that the ratio of arc length to the whole circumference would be the same as the ratio of the central angle to the "whole angle" or 360°.
\(\frac{Arc\hspace{0.1cm}Length}{Circumference}=\frac{Central\hspace{0.1cm}Angle}{360}\)
Putting in 60 for the central angle, we get
\(\frac{Arc\hspace{0.1cm}Length}{Circumference}=\frac{6}{360}=\frac{1}{6}\)
The question is asking what fraction of the circumference is the arc length, so let's isolate the arc length by multiplying the circumference to both sides
\(Arc\hspace{0.1cm}Length=\frac{1}{6}*Circumference\)
This equation in words says that the arc length is one sixth of the circumference, which is exactly what the question is asking.
how do you think khanyi's relationship with her mother has been affected by the role that khanyi has to play
It may be inferred that when the reality program first aired, Khanyi and Khanz's relationship was rocky to say the least. Khanyi had left Khanz to straddle between boarding school and her mother's residence in an attempt to recapture her status.
When the show first aired, it seemed that Khanz knew Khanyi as well as a fan would—through television and social media posts. But it didn't take long for their relationship to grow.
What is an inference?Inferences are processes in thinking that move from premises to logical conclusions; the word infer is etymologically related to "carry forward." Theoretically, inference is typically separated into deduction and induction.

why are so many big cities located along the bank of a river
Answer: Rivers provide great and easy shipping routes and transportation of both goods and passengers.
Explanation:
Answer:I hope this help you out
Explanation:
One reason that many big cities are located along the bank of a river is because rivers have historically provided transportation as well as a source of water for drinking, agriculture, and industry. Additionally, rivers can be used for fishing, which has been an important food source for cities throughout history. Another reason is that the flat land around a river is often more accessible and easier to build on than hilly or mountainous terrain. Finally, rivers have traditionally been used for disposing of waste and sewage, which can be carried away downstream rather than accumulating in the city.

How was Malcolm X's approach to gaining civil rights different from Dr. King's? Why do you think he resisted King's approach?
Answer:
Near the end of his life, Malcolm X publicly recognized that "Dr. King wants the same thing I want — freedom!" But for most of his ministry he did not identify with King and the civil rights movement. Although both Black Muslims and King's Southern Christian Leadership Conference had the same general goals of defeating white racism and empowering African Americans, Malcolm and King had different tended to speak at different venues (street corners vs. churches) and had different aims. Malcolm, who would publicly deny that he was even an American, worked for a Nation of Islam that sought to create a separate society for its members. Malcolm rejected integration with white America as a worthwhile aim (deriding it as "coffee with a cracker") and particularly opposed non-violence as a means of attaining it. "That's what you mean by non-violent," he said, "be defenseless." In Malcolm's mind, the African American could never surrender his right of self-defense against white violence.
Explanation:
I think that because Malcolm X had a different opinion thank King's approach on the civil rights movement he wanted to stick to it.
