Rate of change on a graph.- I'll give brainly for the answer, thank you

Answers

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.

prove the given identity ​

Answers

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.

Which of these statements best describes the relation shown in Item 1?

Answers

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.

1) linear: this equation just gives us a straight line with no curves
2) linear: this equation gives us a horizontal line
3) non linear: the -2x^2 makes the equation a parabola, so the graph is not a straight line. It looks like an upside down u. Therefore because this equation is a parabola, it is not a linear equation
