we can conclude that yes, the function is periodic with period T =  π/2

A function is periodic if for any input X, there exists a value T (where T is the period) such that:

f(x) = f(x + T).

In this particular case, we are told that the period should be π/2, so let's check that.

We can see that:

f(π/4) = 1.2

If we add the period to the argument, we get:

π/4 + π/2 = π/4 + 2π/4 = 3π/4

Now, on the table we can see that:

f(π/4 +π/2 ) = f(3π/4) = 1.2

So at the moment, it seems to be periodic.

Let's try another point.

f(3π/2) = 0.6

If we add the period:

3π/2 + π/2 = 2π

And in the table we can see that:

f( 2π) = 0.6

So we can conclude that yes, the function is periodic with period T =  π/2

Answer:  (1a) 250°  (1b) 70°    (2) see below

Step-by-step explanation:

1a) -110 + 360 (one rotation clockwise) = 250°

1b) 430 - 360 (one rotation counterclockwise) = 70°

2) sec Ф = -8/5    in Quadrant III

Quadrant III identifies that both sin (y) and cos (x) are negative.

sec = r/x --> r = 8, x = -5, and y = -√39

(Use Pythagorean Theorem x² + y² = r² to solve for y)

\(\sin\theta=\dfrac{y}{r}=\dfrac{-\sqrt{39}}{8}\)              \(\csc\theta=\dfrac{r}{y}=\dfrac{-8}{\sqrt{39}}\)  rationalized = \(\dfrac{-8\sqrt{39}}{39}\)

\(\cos\theta=\dfrac{x}{r}=\dfrac{-5}{8}\)                  \(\sec\theta=\dfrac{r}{x}=\dfrac{-8}{5}\)  (GIVEN)

\(\tan\theta=\dfrac{y}{x}=\dfrac{\sqrt{39}}{5}\)              \(\cot\theta=\dfrac{x}{y}=\dfrac{-5}{-\sqrt{39}}\)  rationalized = \(=\dfrac{5\sqrt{39}}{39}\)

The stage of group development that is characterized by disagreements and conflicts is called storming. During this stage, group members may have different ideas and opinions about how to approach tasks and goals, and they may struggle to find a common understanding.

Conflict can arise as individuals compete for leadership roles or try to assert their ideas over others. However, this stage is important for groups to progress towards their goals as it allows for open communication and the airing of different perspectives. Eventually, through negotiation and compromise, groups move on to the norming stage where a common understanding is established and roles are defined. From there, groups move on to performing, where they are able to work together effectively towards their goals.

Finally, the adjourning stage is where the group disbands after reaching their goals or completing their tasks.

In the given question, to approach this, we should have a little understanding of what is a random variable. The random variable here is the distance travelled by the tee shots in a golf.

A random variable is a numerical description of the outcome of a statistical experiment. A random variable that may assume only a finite number or an infinite sequence of values is said to be discrete; one that may assume any value in some interval on the real number line is said to be continuous.

We are given two scenarios in which we are to identify the random variable here.

In the above scenarios, the random variable here is the distance travelled by the tee shots in a golf. The reason is that we can never give an exact value the distance and would lead to an assumption of a finite number of value or an infinite sequence of values to determine this.

Answer:

  A. no

  B. no

  C. obtuse

Step-by-step explanation:

For side lengths to form a triangle, the sum of the shorter two must exceed the longest.

A. 5 + 8 = 13 . . . . a line segment, not a triangle

B. 7 + 12 < 26 . . . . no closure, not a triangle

C. 11 + 15 > 20 . . . . a triangle. A picture shows it to be obtuse

  You can also compare 11² +15² vs 20² ⇒ 346 vs 400. The long side is too long for a right triangle, so the triangle must be obtuse. (The Pythagorean theorem tells you a right triangle with those legs would have a long side of √346 = 18.6.)

In a triangle, The value of x is, 40°

And, The value of y is, 50°

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

We have to given that;

The triangle is show in figure.

We know that;

In a triangle, the pair of two opposite sides are equal then there corresponding angles are also equal.

Now, By figure we can formulate;

⇒ x + x + 100 = 180

Solve for x;

⇒ 2x + 100 = 180

⇒ 2x = 180 - 100

⇒ 2x = 80

⇒ x = 40

Thus, The value of x = 40°

And, We get;

⇒ x° + y° + 90° = 180°

⇒ 40 + y + 90 = 180

⇒ y + 130 = 180

⇒ y = 180 - 130

⇒ y = 50°

Thus, The value of y = 50°

The markup percentage for your tacos is 100%. (option a)

To calculate the markup percentage, we need to compare the profit you make on each taco to the cost of producing that taco. In this case, the cost to produce one taco is $2, and you sell it for $4. The markup can be calculated using the following formula:

Markup Percentage = ((Selling Price - Cost Price) / Cost Price) * 100

Let's plug in the numbers and calculate the markup percentage:

Markup Percentage = (($4 - $2) / $2) * 100

Markup Percentage = ($2 / $2) * 100

Markup Percentage = 1 * 100

Markup Percentage = 100%

These ribbons be awarded to 3 of 13 pigs in 1716

We have given that,

13 pigs are entered in the best pig competition at the country fair the judges will award very special pigs with blue, red, and white ribbons

We have to determine how many different ways can these ribbons be awarded to 3 of 13 pigs.

A permutation of a set is, loosely speaking, an arrangement of its members into a sequence or linear order, or if the set is already ordered, a rearrangement of its elements.

So the judges are going to pick 3 pigs from the 13 to give a ribbon. Since the ribbons are different, the order does matter.

So this is a permutation. This can be set up like this:

Step-by-step explanation:

Let L and W be the length and width of the rectangle, respectively.

We know that the perimeter, P, of a rectangle is given by:

P = 2L + 2W

In this case, P = 16 cm, so we have:

16 = 2L + 2W

Simplifying, we get:

8 = L + W

To find the greatest area of the rectangle, we need to maximize the product of L and W, which is the formula for the area, A:

A = L * W

We can solve for one variable in terms of the other using the equation we found earlier:

L = 8 - W

Substituting this into the formula for the area, we get:

A = (8 - W) * W

Expanding and simplifying, we get:

A = 8W - W^2

To find the maximum value of A, we can use calculus or complete the square. Completing the square, we get:

A = -(W - 4)^2 + 16

Since the square of a real number is always nonnegative, the maximum value of A occurs when (W - 4)^2 = 0, which is when W = 4.

Substituting this value back into the equation for the perimeter, we get:

8 = L + 4

L = 4

Therefore, the rectangle with a perimeter of 16 cm and the greatest area is a square with sides of length 4 cm, and its area is:

A = L * W = 4 * 4 = 16 square centimeters.

The rate of increase in the area of the square is 70 cm²/s when the area of the square is 25 cm².

Each side of a square is increasing at a rate of 7 cm/s. The area of the square is 25 cm².

The area of the square is given by A = a²

Where A is the area of the square and a is the length of the side of the square.

Differentiate both sides of the equation with respect to time we get:

dA/dt = 2a.da/dt

Substitute a = √A in the above equation to get:

dA/dt = 2√A.da/dt

Substitute A = 25 and da/dt = 7 in the equation dA/dt = 2√A.da/dt to get:

dA/dt = 2 x √25 x 7

dA/dt = 2 x 5 x 7

dA/dt = 70 cm²/s

Therefore, the rate of increase in the area of the square is 70 cm²/s.

Transforming the function using f(x - h) shifts its graph h units to the right. Here, we have h = -4, so the graph exists shifted 4 units to the left.

The transformations of functions describe how to graph a function that exists moving and how its shape exists being changed. There exist basically three kinds of function transformations: translation, dilation, and reflection.

Let f(x) = x³ be the original function.

When -5 exists added to the y-value, it moves the point on the graph down 5 units. Compared to f(x), g(x) exists 5 units down.

f(x) = (x + 4)³ - 5

= [x- (- 4) ]³ - 5 (shift 4 units in the negative x direction that exists 4 units left)
