In the figure, PQ // RS. Find the value of x.
Answer:
x=57
Step-by-step explanation:
add a line perpendicular to PQandRS
then 90+90+130+116+2x=540
2x=114
x=57
in the figure PQ//RS
the value of x=33

Which is the graph of a quadratic equation that has a negative discriminant
Answer:
The only one
Step-by-step explanation:
The one that is shown has a negative b^2-4ac value.
We know this because the function has no real roots -> that means that they must be complex, which can only occur if b^2-4ac < 0
Answer:
it's D, the last graph.

4x-1=3(x-1) Please help!
Answer:
x=-2
Step-by-step explanation:
4x-1=3x-3
x=-2
X = -2
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
prove the given identity
Step-by-step explanation:
3. Let us take apart the right side
1+cos2x = 1 + cos^2x - sin^2x
1 - sin^2x = cos^2x
therefore we have 2cos^2x
Therefore we just have cos^2x/cos^2y = 2cos^2x/2cos^2y, which is true.
4. tan(x/2) = +/- sqrt((1-cosx)/(1+cosx)) using half angle identities for sin and cos.
Therefore tan^2(x/2) = (1-cosx)/(1+cosx)
If we multiply top and bottom by tanx, we get
(tanx - sinx)/(tanx + sinx), which is the right side.

A number is divided by 5 then decreased by 5. It becomes -2. Find the number
Convert 2.8 radians to degree measure. Round your answer to the nearest hundredth.
Answer:
16.04°
Step-by-step explanation:
[tex]2.8 \: rad = x \: degrees \\ [/tex]
1rad × 180/π = 57.296°
[tex]x = 2.8 \times \frac{180}{\pi} = 16.0428 \\ x = 16.04[/tex]
How do the graphs of the functions differ from the graph of f(x)=3.5x^3?
For each function, select Steeper, Less steep, or Reflected over the x-axis to describe the differences between the graph of the function and the graph of f(x).
Select all answers that are correct.
Given:
The function is [tex]f(x)=3.5x^3[/tex].
To find:
Whether the given function is Steeper, Less steep, or Reflected over the x-axis to describe the other function.
Solution:
Transformation of function: If f(x) is function and
[tex]g(x)=a\ f(x)[/tex]
Here, a is vertical stretch or compression.
If 0<|a|<1, then g(x) is less steeper than f(x) because f(x) is vertically compressed.
If |a|>1, then g(x) is steeper than f(x) because f(x) is vertically stretched.
If a is negative, the f(x) is reflected over the x-axis, to get g(x).
On comparing the function [tex]p(x)=4.5x^3[/tex] with [tex]f(x)=3.5x^3[/tex], we get 4.5>3.5 So, it is the case vertical stretched and p(x) is steeper than f(x).
On comparing the function [tex]q(x)=-x^3[/tex] with [tex]f(x)=3.5x^3[/tex], we get |-1|=1<3.5 So, it is the case vertical compression and q(x) is less steeper than f(x) and because of negative sign the function is reflected over axis.
On comparing the function [tex]r(x)=3x^3[/tex] with [tex]f(x)=3.5x^3[/tex], we get 3<3.5 So, it is the case vertical compression and r(x) is less steeper than f(x).
Therefore, [tex]p(x)=4.5x^3[/tex] is steeper.
[tex]q(x)=-x^3[/tex] is less steep and reflected over the x-axis.
[tex]r(x)=3x^3[/tex] is less steep.

Rate of change on a graph.- I'll give brainly for the answer, thank you
Answer:
The slope of graph is [tex]\mathbf{\frac{3}{2}}[/tex]
Option C is correct option.
Step-by-step explanation:
We need to find the slope (rate of change) of the graph
The formula to calculate slope is: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
Taking two points from the graph: (You can take any two points from the graph)
Point 1 (-4,-3)
Point 2 (-2,0)
We have: [tex]x_1=-4, y_1=-3, x_2=-2, y_2=0[/tex]
Putting values in the formula and finding slope
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{0-(-3)}{-2-(-4)} \\Slope=\frac{0+3}{-2+4} \\Slope=\frac{3}{2}[/tex]
So, the slope of graph is [tex]\mathbf{\frac{3}{2}}[/tex]
Option C is correct option.

Which of these statements best describes the relation shown in Item 1?
Answer:
It is a many-to-one relation
Step-by-step explanation:
Given
See attachment for relation
Required
What type of function is it?
The relation can be represented as:
[tex]\left[\begin{array}{c}x\\ \\-5\\-2\\1\\5\end{array}\right][/tex] [tex]\left[\begin{array}{c}y\\ \\10\\11\\4\\10\end{array}\right][/tex]
Where
[tex]x = domain[/tex] and [tex]y = range[/tex]
Notice that the range has an occurrence of 10 (twice)
i.e.
[tex](x_1,y_1) = (-5,10)[/tex] and [tex](x_2,y_2) = (5,10)[/tex]
In function and relations, when two different values in the domain point to the same value in the range implies that, the relation is many to one.
