Answer:

Hence, option D is correct (i.e. Distance is not preserved under dilation).

Step-by-step explanation:

<em>" A dilation is a transformation that produces an image that is the same shape as the original, but is a different size ".</em>

A) Angle measure:

Angle measures remains same as there is only a difference in their size the shape does not changes.

Hence angle measure is preserved.

B) Betweenness:

It is also preserved. since if any point in before dilation is between two points than after dilation it remain between them only.

C) Collinearity:

Points remain on the same line.

Hence, it is preserved.

D) Distance:

The distance is not preserved. since the length of the segment increase or decrease in dilation hence distance between two point also increase or decrease.

E) Proportionality:

In a dilation, the sides of the pre-image and the corresponding sides of the image are proportional. Hence it is also preserved.

At Elisa's printing company, there are two kinds of printing presses: Model A, which can print 70 books/ day, and model B, which

Dmitrij [34]

Answer:

9 Model As.

Step-by-step explanation:

Let A represent Press A and let B represent Press B.

So, they own 14 total presses. This means that:

$A+B=14$

They can print 905 books per day, in other words, since A prints 70 per day and B prints 55 per day:

$70A+55B=905$

This is now a system of equations. Solve by substitution. From the first equation, subtract B from both sides:

$A=14-B$

Substitute this into the second equation: "

$70(14-B)+55B=905$

First, we can divide everything by 5 to simplify things:

$14(14-B)+11B=181$

Distribute the left:

$196-14B+11B=181$

Combine like terms:

$-3B+196=181$

Subtract 196 from both sides:

$-3B=-15$

Divide both sides by -3

$B=5$

So, the company has 5 Model B presses.

Which means that the company has 14-5 or 9 Model A presses.

And we're done!

Part A - Construct a circle of any radius, and draw a chord on it. The construct the radius of the circle that bisects the chord

Julli [10]

Answer:

It can be concluded that the intersection of a chord and the radius that bisects it is at right angle. The two are perpendicular.

Step-by-step explanation:

i. Construct the required circle of any radius as given in the question, then locate the chord. A chord joins two points on the circumference of a circle, but not passing through its center.

ii. Construct the radius to bisect the chord, dividing it into two equal parts.

Then it would be observed that the intersection of a chord and the radius that bisects it is at right angle. Thus, the chord and radius are are perpendicular to each other.

The construction to the question is herewith attached to this answer for more clarifications.
