Answer:
{-1, 2, 47}
Choice B
Step-by-step explanation:
Function is g(x) = x² - 2
Domain is the possible set of x values and range is the set of function values for that domain
Here Domain = {- 2, - 1, 7}. This means these are values for which the function value g(x) exists
(Note this is not the entire domain, only a subset of the domain)
At x = - 2, g(x) = (-2)² - 2 = 4 - 2 = 2
At x = - 1, g(x) = (-1)² -2 = 1 -2 = -1
At x = 7, g(x) = (7)² -2 = 49 - 2 = 47
These are the corresponding range values for the given domain
Both domain and range sets are expressed from lowest to highest so we get range of g(x) as

What is value of sin?.
Answers
Let's first review the Sin function before talking about Sin 0. Therefore Sin 0 value is 0.
The Sine, Cosine, and Tangent functions in trigonometry are used to determine the angles and length of a right-angled triangle, respectively.
The relationship between the angle, perpendicular side, and hypotenuse side is defined by the sine function.
Alternatively, you can use sin theta, which is equal to the right-angled triangle's perpendicular to hypotenuse ratio. Sin theta is the angle produced between the hypotenuse and adjacent side.
Definition Of Sin In Relation To Sin 0.
Sin 0 denotes that (x,y) is where the value of the x coordinate is 1, and the value of the y coordinate is 0. (1,0). In this case, the hypotenuse has a value of 1, and the opposing side or perpendicular has a value of 0.
As a result, if we set the numbers in the sin ratio for = 0, the perpendicular side to be 1, and the hypotenuse to be 0, we obtain,
Sin 0 = 0/1
Sin 0 = 0

Write a ytem of three linear equation in two variable o that any two of the equation have exactly one olution, but the entire ytem of equation ha no olution. PLEASE HELP FAST!!!!
Answers
A system of three linear equations in two variables that satisfies the given situation can be x + y = 5, 2x + y = 5, and x + 2y = 5
To satisfy the given situation for a system of three linear equations, write any linear equation as the first equation. Let's say
x + y = 5
For the second equation, multiply the x term of the first equation by any factor, keeping the y term and the constant unchanged.
2x + y = 5
The last equation could be written using the second equation wherein the constant of the variable x and y are interchanged.
x + 2y = 5
Any two of the equations in this system have exactly one solution, because they have a unique solution when we solve them individually. However, when we try to solve the entire system by using all three equations, we find that the system has no solution.
This can be easily seen by solving the system by substitution, elimination, or graphical method.
It is also possible to use different equations but with the same criteria, the key is that at least one of the equations should be the negation or a multiple of another equation.

Quadrilateral CDEF is inscribed in Circle T F Engle DEF is 3X +7 and angle DCF is 2X +8 what is the value of X?
Answers
Since Quadrilateral CDEF is inscribed in Circle A, the value of x is equal to: B. 33.
How to calculate the value of x?Since Quadrilateral CDEF is inscribed in Circle A, we can reasonably infer and logically deduce that line segment DF is the chord of Circle A. Mathematically, an equation which can be used to solve for the value of x in this circle is given by:
m∠DEF + m∠DCF = 180°
Substituting the given parameters into the formula above, we have the following;
(3x + 7)° + (2x + 8)° = 180°
3x + 2x + 8 + 7 = 180°
5x + 15 = 180°
5x = 180° - 15
5x = 165
x = 165/5
x = 33.

In the production range of 2 to 3 combs, the opportunity cost of producing one more comb is d) 0.14 brushes.
Explain about production range refer to:Opportunity cost is the cost of one choice in terms of the best alternative foregone. In this case, the opportunity cost of producing one more comb is the number of brushes that have to be given up in order to produce that additional comb.For example, if the country X is currently producing 2 combs, in order to produce one more comb, 0.14 brushes would have to be given up. This means that for every additional comb produced, 0.14 brushes would have to be sacrificed. This trade-off is reflected in Table 1.3 and is the opportunity cost of producing one more comb in the production range of 2 to 3 combs.In other words, the opportunity cost of producing one more comb is the number of brushes that would have to be sacrificed in order to produce that comb.

A. x + 10 y B. 50( x + y ) C. 40 x + y D. 50 x y
Answers
The total fee that Ratnam should pay the agency for a journey of 50 kilometers, using a linear equation, is A. x + 10y.
How is the total car hire fee determined?The total fee is a function of summing the fixed charge for the first 40 kilometers and the variable charge for additional kilometers traveled.
In this situation, the variable charge per km represents the slope or the unit rate while the fixed charge for 40 kilometers represents the constant in a linear equation.
Flat charge up to 40 kilometers = Rs. x
Variable charge per kilometer after 40 km = Rs. y
Total distance traveled = 50 kilometers
Total fee paid = Rs. x + (50 - 40)y
= x + 10y
Thus, the correct fee that Ratnam should pay is represented by Option A.

Discovering an antiderivative of a function is the process of integration.
What is integration?Adding or adding up the components to get the whole is a process known as integration. Reducing the functions into their component elements is a reverse differentiation procedure. Utilizing a broad scale, this method is utilised to find the sum.
A function's antiderivative is discovered by integration. It is the definite integration if a function can be integrated and if the integral of that function across the domain is finite with the given bounds. When d/dx(F(x) = f(x), dx = F(x) + C. Indefinite integrals are what these are.
As opposed to differentiation, integration is the opposite. In other words, the integral of 2 can be 2x + 3, 2x + 5, 2x, etc. Because of this, we must include a constant when integrating. The integral of 2 is therefore 2x + c, where c is a constant.

the velocity time graph for a cycle is shown. work out the total distance travelled on the cycle. work out the acceleration in the last 8 seconds. Need the answer before 6th of Feb 2023.
Answers
Part A - The cycle has a total distance travelled of 130 meters.
Part B - The cycle has an acceleration of 0 meters per square second at t = 8 seconds.
How to apply kinematics from a graph
In this question we find the case of a graph between time (t), in seconds, and velocity (v), in meters per second, from which we need to determine the total distance travelled (s), in meters, on the cycle and the acceleration (a), in meters per square second, at a given time.
Part A - The total distance travelled is the area below the curve, defined as the sum of the areas of two triangles and rectangle, thus:
s = 0.5 · (6 s) · (10 m / s) + (6 s) · (10 m / s) + 0.5 · (8 s) · (10 m / s)
s = 30 m + 60 m + 40 m
s = 130 m
The total distance traveled by the cycle is 130 meters.
Part B - The acceleration at a given time t is the slope of the curve at point (t, v). In this case, we find that slope can be found by secant line formula:
a = [v(12) - v(6)] / (12 - 6)
a = (0 - 0) / (12 - 6)
a = 0 m / s²
The acceleration of the cycle at t = 8 seconds is equal to 0 meters per square second.

d = √( (x₂ - x₁)² + (y₂ - y₁)²)
The distances are:
between (-3, 2) and (2, 2)
d = √( (-3 - 2)² + (2 - 2)²) = 5
