Answer:

Option A and C have rotational symmetry.

Step-by-step explanation:

The graph of odd functions have rotational symmetry about its origin.

Here the first graph is a graph of f(x)=f(x)=x^3 which is an odd function bearing an exponent of 3.

A function is "odd"  when we plug in any negative value in f(x) then it gives negative of f(x).

And we also know that when a graph is mirroring about the y-axis then it is an even functions.

For even functions we have reflection symmetry rather than rotational symmetry.

The second graph is a graph of f(x)=-modulus (x) which is an even function as we can see that its graph is mirroring about the y-axis.

The third graph is a graph of an ellipse which is possessing  rotational symmetry.

The order of symmetry of an ellipse is generally 2.

Order of symmetry:

The order of rotational symmetry of an object is how many times that object is rotated and fits on to itself during a full rotation of 360 degrees.

So graph A and C have rotational symmetry.

Product of (6x+8us^2)(x-us^2)
Lerok [7]

Answer:

−8s4u2+2s2ux+6x2

Step-by-step explanation:

=(6x+8us2)(x+−s2u)

=(6x)(x)+(6x)(−s2u)+(8us2)(x)+(8us2)(−s2u)

=6x2−6s2ux+8s2ux−8s4u2

=−8s4u2+2s2ux+6x2

Help please. Just need to answer 29-31 then I’m done. Thanks
Free_Kalibri [48]

Answer:

29. See table below

30. See attached graph

31. The slope is m= 0.10

The slope represent the cost for every additional call minute.

Step-by-step explanation:

The cost is $0.5  first minute and $0.10 for any additional minutes

If c is the total cost of a call that last t minutes then;

c= 0.10t + 0.5-----where t is the time the call lasted

29. Use the equation above to create the table as;

t {x}            c{y}

1                  0.6

2                 0.7

3                 0.8

4                 0.9

5                 1.0

6                 1.1

The graph of this plot is as attached , where the coordinates are

{1,0.6} , {2,0.7} ,{3,0.8} ,{4,0.9} ,{5,1.0}, {6,1.1}

The slope can be found using the formula;

m=Δy/Δx

m= 1.1 - 0.6 / 6-1

m= 0.5 / 5 = 0.10

The slope represent the cost for every additional call minute.
