When a set of coordinates on a preimage is multiplied by -n instead of n, the coordinates of the image rotate about the center o

f dilation by 180°. Consider all the potential intervals of n in the table. Enter information in the table to indicate whether the scale factor produces an enlargement, a reduction, or no size change. Also indicate whether the image rotates 180° about the center of dilation.

Answer:

The value of n determines whether the image is bigger or smaller than the preimage. If 0 < n < 1, the image is smaller than the preimage. If n = 1, the image is the same size as the preimage: the two are congruent. If n > 1, the image is larger than the preimage.

Step-by-step explanation:

Cheyenne ran a 6.36-kilometer race in 53 minutes. What was her speed in kilometers per hour?
svlad2 [7]

Answer:

7.23km/h

Step-by-step explanation:

Speed = distance/time

Given

distance = 6.36km and

Time = 53minutes

Convert 53minutes to hour.

60 minutes = 1 hour

53 minutes = x hour

Cross multiply

X hour x 60 = 53

Xhour = 53/60

X = 0.88 hour

Therefore

Speed = 6.36km /0.88hr

= 7.23km/h

<h3>Answer:  x = 16</h3>

============================================

Explanation:

On that diagram, the unmarked angle above the (6x-8) is equal to (5x+12). This is because the unmarked angle and the angle marked with (5x+12) are corresponding angles. Corresponding angles must be congruent if you want line m to be parallel to line n.

From here we add up (5x+12) and (6x-8) and set that sum equal to 180. Solve for x

We get the following:

(5x+12)+(6x-8) = 180

5x+12+6x-8 = 180

(5x+6x)+(12-8) = 180

11x+4 = 180

11x = 180-4

11x = 176

x = 176/11

x = 16
