If “the notation arcsin x represents the inverse function to sine” is true when the sine function is to the interval [ -pi/2, pi/2 ].
What is the sin function?The sine function is one of the three primary functions in trigonometry, the others being cosine, and tan functions.
The confusion is compounded by the fact that we use the notation sin⁻¹(x) interchangeably with arcsin(x), and we call it the inverse sine.
Here is a counterexample disproving your given statement:
Let x = π.
The value π is in the domain of sin(x).
arcsin[sin(π)] = arcsin(0) = 0
arcsin[sin(π)] ≠ π
Therefore arcsin(x) is not the inverse of sin(x).
If you restrict the sine function to the interval [ -pi/2, pi/2 ]. Otherwise, arcsin will not be a function.
Hence, If “the notation arcsin x represents the inverse function to sine” is true when the sine function is to the interval [ -pi/2, pi/2 ].

Unit Test Unit Test Active 1 2 3 4 5 6 7 CO Given fix) = 17- x2, what is the average rate of change in f(x) over the interval [1, 5]? -6, -1/2, 1/4, 1
Answer:
Step-by-step explanation:
Average rate of change is the same thing as the slope. This is a quadratic so the slope is not something that is constant like it is in a line. Here you have the x coordinates of 1 and 5; each one of these x coordinates has a y coordinate that goes with it. If we draw a line from one of these coordinates to another, that line will have a slope. That is the slope we are trying to find. Thus, we need the y coordinates that go with each of these x coordinates. To do that, plug x into the equation and do the math to find y:
Let's start with x = 1.
f(1) = [tex]17-(1)^2[/tex] so
f(1) = 16 and the coordinate is (1, 16).
f(5) = [tex]17-(5)^2[/tex] so
f(5) = -8 and the coordinate is (5, -8). Now we apply the slope formula:
[tex]m=\frac{-8-16}{5-1}=\frac{-24}{4}=-6[/tex] So the answer is -6.
what is the measure of angle TSU?
Answer:
m<TSU = 65
Step-by-step explanation:
As one can see, the measure of angle (RST) is (90) degrees. This is indicated by the box around the angle. As a general rule, when there is a box around an angle, the angle measure if (90) degrees. It is also given that the measure of angle (RSU) is (25) degrees. As per the given diagram, the sum of the measures of angles (RSU) and (UST) is (RST). Therefore, one can form an equation and solve for the measure of angle (UST).
(RSU) + (UST) + (RST)
Substitute,
25 + (UST) = 90
Inverse operations,
25 + (UST) = 90
UST = 65
(<UST) is another way of naming angle (TSU).
Answer:
∠ TSU = 65°
Step-by-step explanation:
∠ RST = 90°
∠ RSU + ∠TSU = ∠ RST , that is
25° + ∠ TSU = 90° ( subtract 25° from both sides )
∠ TSU = 65°

Which of the following is the function for the graph shown?
Answer:
D
Step-by-step explanation:
The zeros from the graph, where it crosses the x- axis are
x = - 2 and x = 3 , then the corresponding factors are
(x + 2) and (x - 3) , then
y = a(x + 2)(x - 3) ( where a is a multiplier )
To find a substitute any point on the graph into the equation
Using (0, - 6 )
- 6 = a(0 + 2)(0 - 3) = a(2)(- 3) = - 6a ( divide both sides by - 6 )
1 = a
y = (x + 2)(x - 3) ← expand using FOIL
y = x² - x - 6 → D

The transformation of the parent graph of y = √x to y = (1/2)√x is a vertical compression by a factor of 1/2.
What is a transformation?A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.
As per the shown graph, for any value of x, the output of the function y = (1/2)√x is half of the output of the function y = √x. This means that the y-values of the transformed graph are compressed vertically by a factor of 1/2 compared to the parent graph, while the x-values remain unchanged.
Visually, the graph of y = (1/2)√x will be flatter and closer to the x-axis than the graph of y = √x, with the same x-intercepts (0,0) and (1,1).
Thus, the y-values of the transformed graph are compressed vertically by a factor of 1/2 compared to the parent graph.

Answer:
see explanation
Step-by-step explanation:
∠ 1 and ∠ 8 , ∠ 2 and ∠ 7 are alternate exterior angles
They are on opposite sides of the transversal and outside the parallel lines
Given ∠ 1 = 60° , then

Answer:
1. <1 and <8
< 2 and <7
2. 60°
Step-by-step explanation:
1. When two lines are cut by a transversal, the pairs of angles on either side of the transversal and outside the two lines are called the alternate exterior angles.
2. If two parallel lines are cut by a transversal, then the alternate exterior angles formed are congruent.
Congruent angles are angles with the same measurement.

Problem: Construct a triangle with interior angle measures of 60° and 60°. Let one of the side lengths be 10. What are the lengths of the other sides?
Answer:
The lengths of the other sides would be 10, as well.
Step-by-step explanation:
Since we already know two of the three angles, we can subtract to find the other angle. The interior angles of a triangle will always add up to 180°. We have 60° and 60°, giving us 120°. 180 - 120 is equal to 60°, so that's the missing angle. Because all of the angles are the same, this is an equilateral triangle, which means the sides also have to be the same length. If one of the sides is 10, all of the sides are 10.
The triangle with sides 10 , 10 and 10 and all angles at 60° is an equilateral triangle
What is an Equilateral Triangle?An equilateral triangle is a triangle in which all three sides have the same length.
Let the triangle be ΔABC , and
∠A = ∠B = ∠C = 60° and AB = BC = CA
Given data ,
Let the triangle be represented as ΔABC
Let the side length of the triangle be AB = 10
Now , the measure of ∠ABC = 60°
And , the measure of ∠BAC = 60°
So , the total sum of all the angles in a triangle = 180°
And , the measure of ∠ACB = 180° - ( 60° + 60° ) = 60°
Therefore , all the angles of the triangle are 60°
So , it is an equilateral triangle
And , the measure of side lengths of the triangle is 10
Therefore , AB = BC = CA = 10
Hence , it is an equilateral triangle

shaun baharat and jagan play hockey , shaun has scored 9 more goals that jagan baharat has scored 6 more goals than shaun , all together they have scored 69 goals , how many did they each score
Let x be the number of goals that Jagan scored, then Shaun scored x + 9 goals and Baharat scored x + 9 + 6 = x + 15 goals.
What in mathematics is a linear equation?
According to Wolfram MathWorld A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."
We know that the total number of goals is the sum of the goals each player scored, which is x + (x + 9) + (x + 15) = 69
We can express this as 3x + 33 = 69
Then we can subtract 33 from both sides to get 3x = 36
Then we divide both sides by 3 to get x = 12
Then we can substitute the value of x back to find the number of goals each player scored:
Jagan: x = 12
Shaun: x + 9 = 12 + 9 = 21
Baharat: x + 15 = 12 + 15 = 27
So Jagan scored 12 goals, Shaun scored 21 goals and Baharat scored 27 goals.

Amy,bob and hadi saved $1012 altogether. Amy saved $85. Hadi saved 3 times as much as the total amount of Amy's and Bob's savings. How much did Bob save?
Answer:
Bob Saves 168$.
Step-by-step explanation:
According to the Question,
Given That, Amy , bob and hadi saved $1012 altogether.Thus, A + B + H = 1012 ⇒ Amy saved $85.
So, B + H = 927 ----- Equation 1
And Hadi saved 3 times as much as the total amount of Amy's and Bob's savings So, H = 3(A + B) ⇒ We Know Amy saved $85.So, H - 3B = 255 ----- Equation 2
Now, Subtract Equation 2 from Equation 1, We get4B = 672 ⇒ B = 168
Bob Saves 168$.

A unit of gas costs 4.2 pence on averge ria uses 50.1 units of gas a week she pays for the gas she uses in 13 weeks work out an estimsate for the amount ria pays
Answer:
Step-by-step explanation:
Cost per unit of gas = 4.2 pence
Average units of gas used per week = 50.1 units
Total cost of gas per week = Cost per unit of gas × Average units of gas used per week
= 4.2 pence × 50.1
= 210.42 pence
= £ 2.1042
Amount ria pays for gas for 13 weeks = cost of gas per week × number of weeks
= 210.42 pence × 13
= 2,735.46 pence
2,735.46 pence = £ 27.3546
