Answer:
The exact value
[tex]sin^{-1} (\frac{-1}{2} ) = \frac{7\pi }{6}[/tex] = 210°
Step-by-step explanation:
Step(i):-
Given that the inverse trigonometry
[tex]sin^{-1} (\frac{-1}{2} )[/tex]
We know that the sine function has negative in third quadrant
[tex]sin^{-1} (\frac{-1}{2} ) = sin^{-1} ( sin (\pi +\frac{\pi }{6} )[/tex]
We have to use trigonometric formula
[tex]sin^{-1} ( sin (x)) = x[/tex]
Step(ii):-
[tex]sin^{-1} (\frac{-1}{2} ) = sin^{-1} ( sin (\pi +\frac{\pi }{6} ) = \pi +\frac{\pi }{6}[/tex]
= [tex]\frac{6\pi +\pi }{6} = \frac{7\pi }{6}[/tex]
Final answer:-
The exact value
[tex]sin^{-1} (\frac{-1}{2} ) = \frac{7\pi }{6}[/tex]

I forgot how to find a function in a graph
Answer:
This graph is NOT a function.
Step-by-step explanation:
A graph is a function only if there is exactly one y-value for every x-value. In this case, there are many x-values that have two y-values, making this graph not a function.

A. x < -1 and x 24
B. x>-1 and x 34
C. -13x34
D. -13x<4
Answer:
B
Step-by-step explanation:
there is a hole at -1, so -1 is less than x and x is greater than or equal to 4
The compound inequality shown on the graph is x < -1 and x≥4.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
We have the graph for the inequality.
The first part of the inequality is
x < -1
and, the second part of inequality x≥4
So, the compound inequality is x < -1 and x≥4.

The points (0,-14), (1,-3), (2,0), (3,5) are on a parabola. Write the function to represent this parabola.
Answer:
y= -4x^2 + 15x - 14
Step-by-step explanation:
A parabola is always in the form y = ax^2 + bx + c.
Substitute each point to produce different equations:
-14 = 0a + 0b + c = c
so c = -14
-3 = a1^2 + b1 + c = a + b - 14
so a + b = 11
0 = a2^2 + b2 + c = 4a + 2b -14 = 0
so 4a + 2b = 14
if we double a + b = 11 we get 2a + 2b = 22
Subtract this from 4a + 2b = 14 and we get 2a = -8 so a= -4 and b = 11 - a = 15
We don't need to use the (3,5) points as we have all the information we need.

feet?
A. 27
B. 26
C. 34
D. 71,644
E. 48
Answer:26
Step-by-step explanation:
a squared+b squared= the hypotenuse squared
Input
10 squared+24 squared=the hypotenuse squared
100+576=676 squared
Now we need to find the square route of 676 because this is the hypotenuse squared, and we need to find the hypotenuse. And the square route of 676 is 26.

3. What are the coordinates of the
image D(0.5, R)(1, 3), where R(−3, 5)
is the center of dilation?
A. (0.5,1.5) B. (-1.5,2.5) C. (3,2) D. (-1,4)
Answer:
d.(-1,4)
Step-by-step explanation:
Option D is correct, the coordinates of the image D are (-1, 4)
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
To find the coordinates of the image D, we need to apply the dilation transformation centered at R(-3, 5). Let the scale factor be k.
The x-coordinate of D will be shifted k times the distance between 1 and -3, which is 4 units, from the x-coordinate of R, which is -3. So we have:
0.5 = -3 + k(4)
Solving for k, we get:
k = 1.375
Similarly, the y-coordinate of D will be shifted k times the distance between 3 and 5, which is 2 units, from the y-coordinate of R, which is 5. So we have
R: (x, y) = (-3, 5)
D: (x, y) = (-3 + 1.375(1 - (-3)), 5 + 1.375(3 - 5))
D: (x, y) = (-1, 4)
Therefore, the coordinates of the image D are (-1, 4), which is option D.

The area of the triangle shown below is B. 42 sq. units, the correct option is B.
What is the area of a triangle?The area of the triangle is defined as the product of half the base and the height of the triangle.
We are given the parameters are;
Length of its base = b units
Its height = h units long,
Then we get:
Area of a triangle = 1/2 b h
We are given that;
Base= 14, Height= 6
Now,
The area of a right triangle is given by:
Area = (1/2) * base * height
Substituting the values;
Area = (1/2) * 14 * 6
= 42 square units
Therefore, the area of triangle will be 42 sq. units.

may someone help me ASAP? I am solving polynomial equations and I don't know how to do it, here is the equation... x^4+11x^2=3x^2+128
Answer:
[tex]x=2\sqrt{2}[/tex], [tex]x=-2\sqrt{2}[/tex], [tex]x=4i[/tex], [tex]x=-4i[/tex]
Step-by-step explanation:
[tex]x^4+11x^2=3x^2+128[/tex]
First, we subtract 128 from both sides:
[tex]x^4+11x^2-128=3x^2[/tex]
Then, we subtract [tex]3x^2[/tex] from both sides:
[tex]x^4+8x^2-128=0[/tex]
Rewrite the equation:
[tex]u^2+8u-128=0[/tex]
Insert and solve:
[tex]u^2+8u-128=0\\u=8,u=-16\\x^2=8:x=2\sqrt{2},x= -2\sqrt{2} \\x^2=-16:x=4i,x=-4i[/tex]

Consider the function f (x) = x (x+3)(x – 4).
What are the zeros of the function?
Answer:
The solutions are:
[tex]x=0,\:x=-3,\:x=4[/tex]
Step-by-step explanation:
Given the function
[tex]f(x) = x(x+3)(x - 4)[/tex]
In order to determine the zeros of the function, we substitute f(x) = 0
[tex]0\:=\:x\left(x+3\right)\left(x\:-\:4\right)[/tex]
switch sides
[tex]x\left(x+3\right)\left(x-4\right)=0[/tex]
Using the zero factor principle
if ab=0, then a=0 or b=0 (or both a=0 and b=0)
[tex]x=0\quad \mathrm{or}\quad \:x+3=0\quad \mathrm{or}\quad \:x-4=0[/tex]
Thus,
x = 0
and solving x + 3 = 0
x + 3 = 0
subtracting 3 from both sides
x + 3 - 3 = 0 - 3
x = -3
and solving x - 4 = 0
x - 4 = 0
x - 4 + 4 = 0 + 4
x = 4
Therefore, the solutions are:
[tex]x=0,\:x=-3,\:x=4[/tex]
