How could the domain of the cosecant function be restricted so that it's inverse is a function?
The Domain of the cosecant function restricted to -π/2 to π/2. Option B is correct.
Function can be defined as the for every independent variable there is certain value of dependent variable.
Here,
Domain of cosecant function is (-∞, ∞) - {nπ}.
The restricted domain of the cosecant function for its inverse to be held is(-π/2, π/2)
Thus, the Domain of the cosecant function restricted to -π/2 to π/2.

X^4 - 36 = 0
Is factoring by polynomials
Answer: (x²-6)(x²+6)
Step-by-step explanation:
1. Look at 36 and determine if there is any factors that will make cancel out the middle term in the polynomial. Which in this case you would be able to use 6.
2. Next, we will reduce the x⁴ into x² since if you multiply x² • x² you will get x⁴ since you add exponents when multiplying.
3. Factor into to binomials which would be (x²−6)(x²+6) and if you want to simplify down further set each equation to 0 and solve and once you do that you would get x=±√6 for x²−6 but for x²+6 it would be imaginary because you can’t square root negative numbers, so in this case it would be −√6i and √6i.
Instructions: Find the missing side lengths. Leave your answers as radicals in simplest form.
Given:
A figure.
To find:
The values of x and y.
Solution:
We know that, in a right angled triangle,
[tex]\sin \theta =\dfrac{Perpendicular}{Hypotenuse}[/tex]
[tex]\sin 60^\circ =\dfrac{x}{16}[/tex]
[tex]\dfrac{\sqrt{3}}{2} =\dfrac{x}{16}[/tex]
Multiply both sides by 16.
[tex]\dfrac{\sqrt{3}}{2}\times 16=\dfrac{x}{16}\times 16[/tex]
[tex]8\sqrt{3}=x[/tex]
And,
[tex]\cos \theta =\dfrac{Base}{Hypotenuse}[/tex]
[tex]\cos 60^\circ =\dfrac{y}{16}[/tex]
[tex]\dfrac{1}{2}=\dfrac{y}{16}[/tex]
Multiply both sides by 16.
[tex]\dfrac{16}{2}=y[/tex]
[tex]8=y[/tex]
Therefore, the missing side lengths are [tex]x=8\sqrt{3}[/tex] and [tex]y=8[/tex].

Researchers recorded that a certain bacteria population declined from 130,000 to 400 in 18 hours. At this rate of decay, how many bacteria was there at 12 hours? Round to the nearest whole number.
Answer:
There were 43,600 bacteria at 12 hours.
Step-by-step explanation:
Rate of Decay
There are several ways to model the rate of decay in a variety of situations. Two of the most-used are exponential decay and linear decay.
The situation expressed in the question talks about a certain bacteria population that went from 130,000 to 400 in 18 hours. This information suggests the linear decay model is being used.
The rate of decay is calculated as the slope of the line.
Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
We are given the points (0;130,000) and (18;400), thus:
[tex]\displaystyle m=\frac{400-130,000}{18-0}[/tex]
m = -7,200
This means the bacteria population decays by 7,200 each hour. Thus, when 12 hours had passed, the bacteria population was:
130,000 - 7,200 * 12 = 43,600
There were 43,600 bacteria at 12 hours.

The length of the third board of his triangular sandbox will be 15ft, 19ft, 221ft, and 30ft.
What is a triangle?A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C.
Given that Mr. Littles is building a triangular sandbox using three boards. He already has two boards that measure 9 feet and 12 feet.
The theorem of triangles states that the sum of the two sides of the triangle is always greater than the third side. Applying the theorem.
x + y > z
9 + 2 < 12 Not satisfy the theorem
9 + 3 = 12 Not satisfy the theorem
9 + 15 > 12
9 + 19 > 12
9 + 21 > 12
9 + 30 > 12
Therefore, the length of the third board of his triangular sandbox will be 15ft, 19ft, 221ft, and 30ft.

Step-by-step explanation:
Triangle ABC is graphed in Quadrant I of a coordinate plane, and none of the vertices have an x-coordinate or
y-coordinate of 0. Triangle ABC is rotated 90° clockwise with the origin as the center of rotation to create triangle
A'B'C'.
Which statement must be true?
А)
The sum of the angle measures of triangle A'B'C' is 90° more than the sum of the angle measures of
triangle ABC
B The side lengths of triangle A'B'C' are greater than their corresponding side lengths of triangle ABC.
Each angle measure of triangle ABC is less than the corresponding angle measure of triangle A'B'C'.
D. The corresponding sides of triangle ABC and triangle A'B'C' are congruent.
Answer:
Step-by-step explanation:
D. the corresponding sides of triangle ABC and triangle A'B'C' are congruent
because the sides do not change their length when we rotate the triangle
