C. 180° rotation .................
weeeeeb [17]4 years ago

Answer:  The answer is (C) 180° rotation.

Step-by-step explanation:  Given that the point A maps to the point A' by a rotation. We are to select the statement that describes the rotation.

In the given figure, the co-ordinates of point A are (-3, 5) and after rotation, the co-ordinates of point A' are (3, -5).

Therefore, the point (x, y) changes to (-x, -y) after rotation. This is the result of 180° rotation.

Therefore, the point A is rotated through an angle of 180° to reach at the point A'.

Thus, the correct option is (C) 180° rotation.

Find the distance between the points (3,9) and (9, 1).
mrs_skeptik [129]

Answer:

Distance is equal to 10.

Step-by-step explanation:

Use the distance formula: d=√((x_2-x_1)²+(y_2-y_1)²)

d = √(9-3)^2 + (1-9)^2

d = √(6)^2 + (-8)^2

d = √36 + 64

d = √100

d = √10

Hope this helps :)

(9,9) (12,15) find the slope between two points
BigorU [14]
<span>(9,9) (12,15)

Find the slope by using the slope formula. 

m = y2 - y1 / x2 - x1
m = 15 - 9/12 - 9
m = 6/ 3
m = 2

The slope = 2</span>

A pole that is 3.2m tall casts a shadow that is 1.29m long. At the same time, a nearby tower casts a shadow that is 39.25m long.
pashok25 [27]

Set up a ratio of height over shadow length:

3.2/1.29 = X/39.25

Cross multiply:

1.29x = 3.2 * 39.25

Simplify:

1.29x = 125.6

Divide both sides by 1.29:

x = 97.364 meters

Round to the nearest meter = 97 meters
