Explain why domain restrictions are necessary to create inverse trigonometric functions rather than relations.
This would make the inverse function a relation rather than a function, and it would fail the vertical line test.
What is trigonometry?
Trigonometry is a branch of mathematics that deals with the relationships between the sides and angles of triangles. It focuses on the study of trigonometric functions, which are functions that relate the angles of a triangle to the ratios of the lengths of its sides.
Inverse trigonometric functions are used to find the angle whose trigonometric ratio is given. For example, if we know that sin θ = 1/2, we can use the inverse sine function to find the angle θ, which is sin^-1(1/2) = 30°.
However, inverse functions must be functions, meaning that they must pass the vertical line test, where each input (x) produces exactly one output (y). To ensure that inverse trigonometric functions meet this criteria, we need to restrict the domain of the original trigonometric functions.
Trigonometric functions are not one-to-one functions, which means that multiple angles can produce the same value of a trigonometric ratio. For example, sin 30° = sin 150° = 1/2. If we were to define the inverse sine function as the inverse of the sin function without a domain restriction, we would have multiple possible outputs for the same input.
Therefore, this would make the inverse function a relation rather than a function, and it would fail the vertical line test.

Zendaya randomly selected marbles from a bag during a probability experiment. She completed 50 rounds and recorded the results in the table shown. Based on the information from her experiment, in how many of the next 200 rounds would she pick a blue marble?
We can expect her to pick about 70 blue marbles in the next 200 rounds.
How many of the next 200 rounds would she pick a blue marble?We must divide the number of blue marbles by the total number of marbles to determine the likelihood of selecting a blue marble in a single round:
P(blue) = 14/40 = 7/20
Since the experiment has been conducted 50 times, we may anticipate that the proportion of blue marbles will eventually be around 7/20. This suggests that in the subsequent 200 rounds, Zendaya will likely choose to focus on:
70 blue marbles result from P(blue) 200 = (7/20) 200.
So, in the following 200 rounds, we can anticipate her choosing roughly 70 blue marbles.

What is the cost price if the selling price = $980 and the loss = 12%?
Therefore, the cost price is $1113.64 if the selling price is $980 and the loss is 12%.
What is cost price?Cost price (also known as CP) is the amount of money that is required to produce or purchase a particular product or service. It includes all the expenses incurred in the production or purchase of a product, such as the cost of raw materials, labor, transportation, rent, and other overhead expenses. The cost price is an important factor in determining the profit margin of a business, as it is used to calculate the selling price of a product or service. In general, the cost price is the amount that a seller pays to acquire a product, while the selling price is the amount that a buyer pays to purchase the same product.
Let's assume that the cost price is "C".
We know that the selling price (S) is $980, and the loss percentage is 12%.
We can use the formula for calculating the cost price:
C = S / (1 - Loss%)
where Loss% is expressed as a decimal (i.e., 12% = 0.12).
Substituting the values, we have:
C = $980 / (1 - 0.12)
C = $980 / 0.88
C = $1113.64

A regular hexagon with sides of 3" is inscribed in a circle. Find the area of a segment formed by a side of the hexagon and the circle.
(Hint: remember Corollary 1--the area of an equilateral triangle is 1/4 s2 √3 .)
The area of the segment formed by a side of the hexagon and the circle is (3π - 9 √(3)) / 4 square inches.
How to calculate area of segment formed?A regular hexagon ABCDEF inscribed in a circle with center O. Let's consider the segment bounded by side AB and the arc ACB. We want to find the area of this segment.
First, find the central angle of the sector AOC. Since the hexagon is regular, the central angle of each sector is 60 degrees. Therefore, the central angle of AOC is 120 degrees.
Next, find the area of sector AOC by using the formula for the area of a sector:
Area of sector AOC = (central angle / 360) × π × radius²
= (120 / 360) × π × (3 / 2)²
= (1 / 3) × π × 9 / 4
= (3 / 4) × π
Now, find the area of triangle AOB. Since the hexagon is regular, triangle AOB is equilateral with side length 3". Therefore, use the formula for the area of an equilateral triangle:
Area of triangle AOB = (1 / 4) × (3)² × √(3)
= (9 / 4) × √(3)
Finally, find the area of the segment by subtracting the area of triangle AOB from the area of sector AOC:
Area of segment AB = Area of sector AOC - Area of triangle AOB
= (3 / 4) × π - (9 / 4) × √(3)
= (3 π - 9 √(3)) / 4
Therefore, the area of the segment formed by side AB and the circle is (3 π - 9 × √(3)) / 4 square inches.

A parabola opening up or down has vertex (0, 1) and passes through (8, 17). Write its
equation in vertex form.
Answer: y = (1/4)x^2 + 1
Step-by-step explanation:
The equation of a parabola in vertex form is given by:
y = a(x-h)^2 + k
Where (h,k) is the vertex of the parabola and "a" is a coefficient that determines the shape of the parabola.
In this case, the vertex is given as (0,1), so h=0 and k=1. Also, the parabola passes through the point (8,17), which means that when x=8, y=17. We can use this information to solve for "a".
Substituting the values of h, k, x, and y in the equation, we get:
17 = a(8-0)^2 + 1
Simplifying this equation, we get:
17 - 1 = 64a
16 = 64a
a = 16/64
a = 1/4
Now that we know the value of "a", we can substitute it in the vertex form equation to get the final equation of the parabola:
y = (1/4)(x-0)^2 + 1
Simplifying this equation, we get:
y = (1/4)x^2 + 1
Therefore, the equation of the parabola in vertex form is y = (1/4)x^2 + 1.
Explanation:
We start with the general equation of a parabola in vertex form and substitute the given values of the vertex and the point that the parabola passes through. Then, we solve for the coefficient "a" by simplifying the resulting equation. Once we have the value of "a", we substitute it in the vertex form equation to obtain the final equation of the parabola.

The answer of the given question based on proofing Circle M and Circle N are similar the correct option is (c) Translate the circle M onto point P and dilate the image with scale factor PQ/MN.
What is Scale factor?A scale factor is a mathematical ratio that describes how the size of an object or a figure changes between two similar shapes. In geometry, two figures are considered similar if they have the same shape, but not necessarily the same size.
The scale factor is defined as ratio of any two corresponding lengths in two similar figures. It is usually denoted by letter "k", and can be calculated as:
k = length of corresponding side in the larger figure / length of corresponding side in the smaller figure
The correct answer is (c):
Translate the circle M onto point P and dilate the image with scale factor PQ/MN.
To prove that Circle M and Circle P are similar, we need to show that they have the same shape, which means that corresponding angles are congruent and corresponding sides are proportional.
Translation is a transformation that preserves shape, so we can translate Circle M onto Circle P to make them coincide. Then, we can dilate the image with a scale factor that preserves the ratio of the radii of the circles.
The scale factor that preserves the ratio of the radii is PQ/MN, because PQ is the corresponding radius of Circle P, and MN is the corresponding radius of Circle M. Therefore, dilating the image of Circle M with a scale factor of PQ/MN will result in a circle that is similar to Circle P, with corresponding angles congruent and corresponding sides proportional.

A rectangular park measuring 200m by 100m has a 2m flower border constructed around the two longer sides and one shorter side. Also a circular fish pond of diameter 20m is in the center of the park and the remainder of the park is grassland. Calculate the following areas correct to the nearest square meters. a) the fish pond. b) the flower borders. c) the grassland. d) the perimeter of the park.
Step-by-step explanation:
a) The area of the fish pond is given by the formula:
Area = πr^2
where r is the radius of the pond (which is half of the diameter). So, in this case, r = 10m.
Area = π(10m)^2
Area = 100π m^2
Area ≈ 314 m^2 (rounded to the nearest square meter)
b) The flower border has a width of 2m on the two longer sides and one shorter side of the rectangular park. So, we need to find the area of three strips of land, each of which is 2m wide and has a different length.
The length of the two longer sides is 200m, so the total length of the two strips along these sides is:
2 × 200m = 400m
The length of the shorter side is 100m, but we need to subtract the width of the fish pond (which is 20m) from it, since the flower border does not extend around the pond. So, the length of the strip along this side is:
100m - 20m = 80m
Therefore, the total area of the flower border is:
2m × 400m + 2m × 80m = 960m^2
c) The grassland is the remaining area of the rectangular park after we subtract the area of the fish pond and the flower border from the total area of the park.
The total area of the park is:
200m × 100m = 20,000m^2
The area of the fish pond is:
π(10m)^2 ≈ 314m^2
The area of the flower border is:
960m^2
So, the area of the grassland is:
20,000m^2 - 314m^2 - 960m^2 = 18,726m^2
d) The perimeter of the park is the sum of the lengths of all its sides.
The two longer sides have a length of 200m each, but we need to add the lengths of the two flower borders (each of which is 2m wide), so the total length of the two longer sides is:
200m + 2m + 2m = 204m
The shorter side has a length of 100m, but we need to add the length of the flower border (which is 2m wide), so the total length of the shorter side is:
100m + 2m = 102m
The perimeter of the park is:
204m + 204m + 102m = 510m
Therefore, the perimeter of the park is 510 meters.
what signs are sin(100°) and tan(100°)?
A)sin(100°) >0 and tan (100°) < 0
B) they both positive
c) sin(100°) < 0 and tan (100°) > 0
d) they both negative
Answer:
A)sin(100°) >0 and tan (100°) < 0
Step-by-step explanation:
You want to know the signs of sin(100°) and tan(100°).
Quadrant100° is an angle in the 2nd quadrant, where angles between 90° and 180° lie.
In that quadrant, the sine function is positive, and the cosine function is negative. The tangent is the ratio of sine to cosine, so the tangent is negative in the 2nd quadrant.
sin(100°) > 0tan(100°) < 0__
Additional comment
Of course, your calculator can help you figure this out. Be sure it is in degrees mode.
The second attachment shows you sine is positive above the x-axis; cosine is positive to the right of the y-axis. Everything else derives from this.
