The co-terminal angle to 5π/6 in the unit circle is C. 17π/6

Co-terminal angles in a unit circle are angles that share the same terminal point

Given the angle 5π/6, we desire to find the angle that shares the same terminal point in the unit circle. We proceed as follows.

We know that x = 5π/6 + 2π

Taking the L.C.M which is 6, we have that

x = (12π + 5π)/6

x = 17π/6

So, the angle is C. 17π/6

Step-by-step explanation:

As per the given bar graph, we can draw the following conclusions:

Net exports for United States = ~ -110 Billion Dollars (It means import of 110 Billion Dollars)

Net exports for Denmark = ~ -30 Billion Dollars (It means import of 30 Billion Dollars)

Net exports for China = ~ 115 Billion Dollars

Net exports for Germany = ~ 35 Billion Dollars

We have to find the sum of net exports of Germany and China:

\(\Rightarrow\) 35 + 115 = 150 Billion Dollars.

Hence, correct answer is d. 150 Billion Dollars.

Answer:

Distance covered = 2198 meters, Displacement = 0 meters

Step-by-step explanation:

To find the distance covered by the athlete, we need to calculate the circumference of the circular track. The diameter is given as 200 m, so the radius can be found by dividing the diameter by 2:

Radius = Diameter / 2 = 200 m / 2 = 100 m

The circumference of a circle can be calculated using the formula:

Circumference = 2 * π * Radius

Plugging in the values, we get:

Circumference = 2 * 3.14 * 100 m = 628 m

Therefore, the distance covered by the athlete in one round is 628 meters.

Next, we need to calculate the total time in seconds for 2 minutes 20 seconds.

2 minutes = 2 * 60 seconds = 120 seconds

Total time = 120 seconds + 20 seconds = 140 seconds

To find the number of rounds completed in 140 seconds, we divide the total time by the time taken for one round:

Number of rounds = Total time / Time for one round

Number of rounds = 140 seconds / 40 seconds = 3.5 rounds

Since the athlete completes 3.5 rounds, we need to calculate the distance covered for 3.5 rounds:

Distance covered = Distance per round * Number of rounds

Distance covered = 628 meters/round * 3.5 rounds = 2198 meters

Therefore, the distance covered by the athlete at the end of 2 minutes 20 seconds is 2198 meters.

To find the displacement, we need to consider the starting and ending points of the athlete. Since the athlete completes an integral number of rounds (3 rounds) and an additional half-round (0.5 rounds), the starting and ending points coincide.

Hence, the displacement at the end of 2 minutes 20 seconds is zero.

Answer:

At the end of 2 minutes 20 seconds, the total distance covered = 2198 (meters), and the total displacement = 200 (meters).

Step-by-step explanation:

Given,

Diameter of circular track, D = 200 m

Time required to complete one round, T = 40 s

For Distance:

Since,

R = D/2 ....(i)

R = 200 m / 2

R = 100 m

where, R ⇒ Radius of Track

D ⇒ Diameter of track

The circumference of the track can be calculated using the formula:

Circumference, C = 2 × π × R ....(i)

Putting the value of R

C = 2 × 3.14 × 100 m

C = 628 m

Therefore, the distance covered by the athlete in one round is 628 meters.

To calculate the total time in seconds,

2 minutes = 2 × 60 seconds = 120 seconds

Total time, t = 120 seconds + 20 seconds

Total time, t = 140 seconds

We can calculate the total number of rounds as,

Total number of rounds, N = Total time / Time for one round   ....(iii)

Total number of rounds, N = 140 seconds / 40 seconds

Total number of rounds, N = 3.5 rounds

Therefore, we can calculate distance as,

Distance covered, d= Distance per round × Number of rounds  ....(iv)

d = 628 (meters/round) × 3.5 (rounds)

Distance covered, d = 2198 meters

To find displacement,

First, we need to know the number of complete rounds the athlete covered because a displacement of a full round is zero.

Since there are 3.5 rounds, there are 3 complete rounds and one-half rounds.

We know that the displacement of the half-round will equal the diameter of the circular track since displacement is the shortest path between the initial and final positions.

therefore, total displacement = displacement of half round.

Total Displacement = Diameter of circular track

Total displacement = 200 m

Hence, at the end of 2 minutes 20 seconds,

the total distance covered = 2198 (meters), and the total displacement = 200 meters.

Answer:

Step-by-step explanation:

what we know is that 45% of the total was 180 (they voted red)

55% of the total voted blue.

To find the total, we need to set up a cross-multiplication equation

180/45 = ?/100

180 times 100 is 18000

18000/45 = 400

400 students were surveyed in total

we can check this by getting 55% of this, and adding it to 180.

If it equals to 400, then we're right.

55% of 400 = 220

220 + 180 = 400

The revenue, the company should manufacture approximately 4,800 units of racing bicycles and 1,200 units of mountain bicycles.

To find the values of x and y that maximize the revenue, we need to optimize the given revenue function R = -6x^2 - 10y^2 - 2xy + 32x + 84y. The revenue function is a quadratic function with two variables, x and y. To find the maximum value, we can take partial derivatives with respect to x and y and set them equal to zero.

Taking the partial derivative with respect to x, we get:

∂R/∂x = -12x + 32 - 2y = 0

Taking the partial derivative with respect to y, we get:

∂R/∂y = -20y + 84 - 2x = 0

Solving these two equations simultaneously, we can find the values of x and y that maximize the revenue.

From the first equation, we can express x in terms of y:

x = (32 - 2y)/12 = (8 - 0.5y)

Substituting this value of x into the second equation, we get:

-20y + 84 - 2(8 - 0.5y) = 0

-20y + 84 - 16 + y = 0

-19y + 68 = 0

-19y = -68

y = 68/19 ≈ 3.579

Plugging this value of y back into the expression for x, we get:

x = 8 - 0.5(3.579)

x ≈ 4.711

Since x and y represent thousands of units, the company should manufacture approximately 4,800 units of racing bicycles (x ≈ 4.711 * 1000 ≈ 4,711) and 1,200 units of mountain bicycles (y ≈ 3.579 * 1000 ≈ 3,579) to maximize the revenue.

Answer:

It is not a rhombus, because all the internal angles are equal.

Step-by-step explanation:

A rhombus is a figure that has four sides of equal length, and 2 internal angles that are smaller than the other two internal angles.

First, let's look at figure ABCD.

We can see that all the sides have equal length by just counting the number of squares that each side takes (each side is 12 units long)

So now we need to see the angles.

Remember that if two lines are perpendicular, then the angle formed by those two lines is exactly 90°.

We can see that the segment BC is horizontal  (the y-value of B is the same than the y-value of C)

While the segment CD is vertical (the x-value of C is the same than the x-vale of D)

Then one segment is horizontal, and the other is vertical, which means that the segments are perpendicular, thus the angle C is 90°.

Now we can do the same for segments CD and DA

We already know that CD is a vertical segment.

For segment DA we can see that the y-value of D is the same as the y-value of A, then this segment is horizontal, this means that segments CD and DA are perpendiculars, which means that D = 90°.

Because DA is parallel to BC, and CD is parallel to BA, we can conclude that:

A = 90°

B = 90°

Then all the angles are equal, so this is not a rhombus. (it is a square)

The statement is True only for independent events and False otherwise. The statement "p (A ∩ B) = p(A). p(B)" is not always true for any two events A and B defined on a sample space S of an experiment.

This equation only holds true if A and B are independent events, meaning that the occurrence of one event does not affect the probability of the other event happening. In other words, p(A|B) = p(A) and p(B|A) = p(B).

If A and B are dependent events, meaning that the occurrence of one event affects the probability of the other event happening, then the equation does not hold true. In this case, the probability of A and B occurring together (p(A ∩ B)) would be less than the product of the probabilities of A and B occurring separately (p(A).p(B)).

Therefore, the statement is not always true and depends on whether A and B are independent or dependent events.

Blinding refers to the nondisclosure of the treatment an experimental unit is receiving in a controlled experiment.

Blinding is a technique used in experimental design to reduce bias and improve the validity of results. It refers to the practice of not revealing to the experimental units (e.g., participants, animals) or the experimenters which treatment they are receiving in a controlled experiment.

Blinding is used to eliminate potential sources of bias that might influence the results of the experiment. For example, if the participants are aware of the treatment they are receiving, they might behave differently and affect the results. Similarly, experimenters might unconsciously treat participants differently based on their knowledge of the treatment, which could also affect the results.

The length of arc EG is approximately 7.35 units.

To find the length of arc EG, we need to use the formula:

length of arc = (central angle/360°) × 2πr

where r is the radius of the circle and the central angle is in degrees.

We are given that m∠EFG = 58°, and EF = 6 units. Since EF is a chord of the circle, we can use the chord-chord angle theorem to find that m∠EGF = ½(180° - 58°) = 61°.

Now, we can use the Law of Cosines to find the length of GE:

GE² = EF² + FG² - 2(EF)(FG)cos(∠EGF)

GE² = 6² + FG² - 2(6)(FG)cos(61°)

Since FG = 2r (because it is the diameter of the circle),

GE² = 36 + (2r)² - 12r cos(61°)

We can simplify this to:

GE² = 4r² - 12r cos(61°) + 36

GE² = 4(r² - 3r cos(61°) + 9)

Now, we can use the formula for the length of the arc:

length of arc EG = (m∠EGF/360°) × 2πr

length of arc EG = (61/360) × 2πr

length of arc EG = (61/180) × πr

Substituting the expression for GE² in terms of r, we get:

length of arc EG = (61/180) × π √[4(r² - 3r cos(61°) + 9)]

We can now use a calculator to find the approximate value of the length of arc EG.

Rounded to the nearest hundredth, the length of arc EG is approximately 7.35 units.
