Step-by-step explanation:

(i) The set of boundary points of S is {1}.

(ii) There are no interior points in S.

(iii) S is not an open set because it does not contain any interior points.

(iv) S is a closed set because it contains all of its boundary points.

Let's analyze the set S step by step:

(i) Boundary points of S:

A boundary point of a set is a point that is neither an interior point nor an exterior point. In this case, since S consists of the elements x = 1 - 1/n for n = 1, 2, 3, ..., we can see that as n approaches infinity, x approaches 1. So, the set of boundary points of S is {1}.

(ii) Interior points of S:

An interior point of a set is a point that has an open neighborhood contained entirely within the set.

In this case, since S is defined as x = 1 - 1/n for n = 1, 2, 3, ..., we can see that as n increases, x approaches 1.

However, for any n, we can always find another n' greater than n such that 1 - 1/n' is closer to 1.

Therefore, there are no interior points in S.

(iii) S as an open set:

An open set is a set that contains all of its interior points.

Since S has no interior points (as discussed in part ii), it cannot contain all of its interior points.

Therefore, S is not an open set.

(iv) S as a closed set:

A closed set is a set that contains all of its boundary points.

In this case, the set of boundary points of S is {1}, and this set is contained within S itself.

Therefore, S contains all of its boundary points and is considered a closed set.

In summary, the set S has a single boundary point {1}, no interior points, is not an open set, and is a closed set.

The equation \(ax(t) = -(18 m/s^2)cos(33t)\) describes the acceleration of an oscillator. The acceleration varies sinusoidally with time, following a cosine function, and has a maximum value of \(-18 m/s^2\).

The given equation \(ax(t) = -(18 m/s^2)cos(33t)\) represents the acceleration of an oscillator undergoing simple harmonic motion. In this equation, t represents time measured in seconds.

The term cos(33t) indicates that acceleration varies sinusoidally with time. The cosine function has a period of 2π, meaning it completes one full cycle over the interval [0, 2π]. The coefficient 33 in front of t determines the frequency of oscillation. In this case, the oscillator completes approximately 33 cycles per second.

The negative sign indicates that the acceleration is directed opposite to the displacement of the oscillator. As the oscillator moves in one direction, the acceleration pulls it back in the opposite direction, causing it to oscillate around a stable equilibrium position.

The maximum acceleration is given by \(-18 m/s^2\), which represents the amplitude of the oscillation. The acceleration varies between \(-18 m/s^2\) and \(18 m/s^2\), with the maximum magnitude occurring when the cosine function is at its peak value of 1 or -1.

Overall, the equation describes the acceleration of an oscillator undergoing simple harmonic motion, providing information about its amplitude, frequency, and direction of motion.

Step-by-step explanation:

The composite function that can be used to calculate the final price of Jonah's car is f[c(p)] = 0. 9265p.

A composite function is a function that is in another function, such that on solving the composite function the result is the same as the function solve individually.

We know that the sale price of Jonah's car is c(p) = 0. 85p, where p is the original price of the car. Also, the tax on the car is 9% of the sale price, and the final price of the car is f(c) = 1. 09c, including tax, therefore, the composite function can be written as,

\(f(c) = 1.09 c\)

We already know the value of c, therefore,

\(f(c(p)) = 1.09 (0.85p)\\\\f(c(p)) = 10.9265(p)\)

Hence, the composite function that can be used to calculate the final price of Jonah's car is f[c(p)] = 0. 9265p.

Answer:

y=2x+4

Step-by-step explanation:

Answer:

The slope-intercept equation is y=2x+4

Step-by-step explanation:

The y-intercept is where it crosses the y-axis, so 4, and to find the slope find perfect points or pretty points and rise then run.  I took the point (0,4) and found the next pretty point (1,6) and rise/run it. In order to get to the next point  you have to rise 2 and run 1 or 2/1 which is 2, so the slope is 2, then you plug it into the equation y=mx+b the y=intercept is b and the slope is m.  

Answer:

a.) 130°

b.) 70°

Step-by-step explanation:

For a given triangle

The sum of all angles on a straight line is equal to 180°

Now,

50° + a = 180°

Subtract 50° from each side we get,

50° - 50° + a = 180° - 50°

a = 130°

Thus, The size of the angle marked a is 130°

The sum of all angles in a triangle is equal to 180°

Now,

b + 50° + 60° = 180°

b + 110° = 180°

Subtract 110° from both side we get,

b + 110° - 110° = 180° - 110°

b = 70°

Thus, The size of the angle marked b is 70°

Drinking iced coffee more often is associated with feeling more awake is most likely correlation and causation.

A relationship that most likely reflects correlation and causation is "Drinking iced coffee more often is associated with feeling more awake." The reason for this is that drinking iced coffee directly affects the level of alertness, which causes a change in the feeling of being awake.

This relationship suggests a cause-and-effect relationship between drinking iced coffee and feeling awake.

On the other hand, "Drinking iced coffee more often is associated with using a fan more often" and "Drinking iced coffee more often is associated with wearing shorts more often" do not reflect a cause-and-effect relationship.

The two variables are merely associated with each other, but there is no direct cause-and-effect relationship between them. It could be that both variables are related to a third factor, such as the weather, or that they are simply independent of each other.

In conclusion, when determining whether a relationship reflects correlation and causation, it is important to consider if there is a direct cause-and-effect relationship between the two variables.

EXPLANATION:

Given;

We are told that a baseball team scores in each of their first 5 innings. After that they do not score a run for the next 10 innings.

Let x represent the inning of the game and y represent the total number of runs.

Required;

Sketch a graph that shows the relationship between x and y.

Step-by-step explanation;

With each run the team scores points, that simply means as x increases, y also increases. That signifies a positive relationship between both variables. A positive relationship will be an upward sloping line (from left to right). At the point where the team does not score any more points, the line does not rise.

So the innings (the x-axis) moves towards the right while the runs does not move at all up till 10 innings.

This is best described by the graph labelled C.

ANSWER:

Graph C best represents the situation described

A. The relative frequency of the people that had mechanical issues is 30%.

B. The relative frequency of the people that did not have mechanical issues is 70%.

C. The relative frequencies in (a) and (b) suggest that the new car has been relatively unreliable, as 30% of buyers experienced mechanical issues within the first two years. This suggests that the car has not been built to a high standard of quality, and that buyers should be prepared for potential issues with the car.

Y is expected to increase by 2 units.

A single dependent variable and several independent variables can be analyzed using the statistical technique known as multiple regression. In order to forecast the value of the single dependent value, multiple regression analysis uses independent variables whose values are known.

In a multiple regression, the impact of numerous explanatory variables on a particular outcome is taken into account. When all other factors in the model are kept constant, it assesses the relative impact of these independent or explanatory variables on the dependent variable.

Multiple regression model =>

\(Y = 7 + 2x_1 + 9x_2\)

Answer:

-0.7071.

Step-by-step explanation:

The value of function sin 315 is -1/2.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

Sin 315 degrees can be found by using the unit circle.

The unit circle is a circle with the radius of one centered at the origin of a coordinate plane.

Every point on the unit circle is a point that is one unit away from the origin.

The unit circle is used to help find the exact values of the trigonometric functions at specific angles.

The angle 315 degrees is in the fourth quadrant of the unit circle, so the x-coordinate is negative and the y-coordinate is negative.

Using the x-coordinate, we can calculate the sine to be -1/2.

Hence, the value of function sin 315 is -1/2.
