Calculate the length of x.
Answer:
B
Step-by-step explanation:
Use the pythagorean theorem to find the hypotenuse. You can do this by squaring 12 and 11 (separately) and then adding those together. You'll get 265. However, since this is c squared and not c, you have to find the square root for the correct answer. The square root of 265 is approximately 16.28. Hope this helps!

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.

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.

Answer:
B also the full name of vertically angles is called the vertically opposite angle theorem or voat
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.

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]

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.

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.
