Which transmition will change figure A into figure B in math
Angelina_Jolie [31]

Answer:

The figures informed are in different scales and mirrored in this way it will be necessary to rotate 180 about the origin, dilate by a scale factor of 2/3.

Step-by-step explanation:

What is figure rotation?

Rotation is the "turn" of a shape around a point called the center of rotation. The distance to the center of rotation remains constant and the measure of rotation is called the angle of rotation.

In this case, first the figure must be rotated 180 degrees since the images are mirrored and then change the scale so that a dilation of 2/3 occurs.

Tobias sent a chain letter to his friends, asking them to forward the letter to more friends. The number of people who receive t
dybincka [34]

Answer:

        P(t)=37\cdot 4^{t/9.1}

Explanation:

This is an exponential growing: there is a constant growing<em> factor </em>which multiplies the value number of letters sent every week.

The growing factor <em>4 letters every 9.1 weeks</em> means that every 9.1 weeks the number of letters is multiplied by 4.

Then, if the number of weeks is t, the number of times the number of letters increase is t/9.1.

Then, the exponential<em> function</em> <em>that models the number of people who receive the email t weeks since Tobias initially sent the chain letter</em>, has the form:

        P(t)=Initial\text{ }value\cdot 4^{(t/9.1)}

<em>Tobias initially sent the chain letter to 37 friends</em>; thus, the initial value is 37, and the complete function is:

        P(t)=37\cdot 4^{t/9.1}, where t is the number of weeks since Tobias initially sent the chain letter.

What is the name of the point from which a dilation is drawn?
dedylja [7]

For this case, the first thing you should do is know that dilation is a transformation that is used<em> to lengthen or shorten a geometric figure. </em>

Geometric figures can be triangles, squares, circles, or any polygon.

There is a point on the plane, at which the dilation begins to be drawn.

This point on the plane is what we know as the center of dilation .

Answer:

B. the center of dilation
