Find the midpoint of the segment with the given endpoints. ​ (9​,9​) and ​(6​,8​)
mars1129 [50]

<u>Answer:</u>

The mid-point is (7.5, 8.5).

<u>Step-by-step explanation:</u>

We are given two points (9​,9​) and ​(6​,8​) as the endpoints for a line segment and we are to find the midpoint of this segment.

We know that the formula for finding the mid point is:

<em>Mid point = (\frac {x_1 + x_1 }{ 2 } ,\frac { y_1 + y_2} {2} )</em>

So substituting the given values of the coordinates of the endpoints in the above formula to get:

= (\frac {9 + 6}{2} , \frac {9 + 8}{2} )

= (\frac {15}{2} , \frac {17} {2} )

=(7.5, 8.5)

Therefore, the mid-point is (7.5, 8.5).

Circle A has center (0, 0) and radius 3. Circle B has center (-5, 0) and radius 1. What sequence of transformations could be use
Dmitrij [34]

A translation of T(x, y) = (- 5, 2) and a dilation with center (- 5, 2) with a scale factor of 1 / 3 are necessary to transform circle A into circle B. (Correct choice: D)

<h3>What sequence of rigid transformations can be done on a circle</h3>

In this problem we must determine the sequence of transformations require to transform circle A into circle B. From analytical geometry we know that the equation of the circle in standard form is:

(x - h)² + (y - k)² = r²

Where:

  • (h, k) - Coordinates of the center.
  • r - Radius of the circle.

Then, we need to apply the following rigid transformations:

Translation

f(x, y) → f(x - h, y - k), where (h, k) is the translation vector.

Dilation with center at the center of the circle

r → k · r, where k is the scale factor.

The circle A is represented by x² + y² = 3, then we derive the expression for the circle B:

f(x, y) → f(x + 5, y - 2)

(x + 5)² + (y - 2)² = 9

r → k · r

(x + 5)² + (y - 2)² = (1 / 3)² · 9

(x + 5)² + (y - 2)² = 1

Then, a translation of T(x, y) = (- 5, 2) and a dilation with center (- 5, 2) are necessary to transform circle A into circle B.
