To find the distance of A'B' after the reflection over the x-axis and rotation of 299° clockwise, we first need to determine the coordinates of A and B.

Let's assume that the coordinate of A is (x1, y1) and the coordinate of B is (x2, y2).

Given AB = 15 inches, we can use the distance formula to find the distance between A and B:

AB = √((x2 - x1)^2 + (y2 - y1)^2) = 15

Since we are reflecting over the x-axis, the coordinates of A will become (x1, -y1) and coordinates B will become (x2, -y2).

After the reflection over the x-axis, the coordinate of A will become (x1, -y1) and the coordinate of B will become (x2, -y2).

Now, we need to rotate the reflected points A' and B' by 299° clockwise.

To rotate a point (x, y) by an angle θ clockwise, the new coordinates (x', y') can be determined as follows:

x' = x*cos(θ) - y*sin(θ)
y' = x*sin(θ) + y*cos(θ)

After rotating both points, we can use the distance formula to find the distance between the two points A' and B'.

Finally, the distance between A' and B' after the reflection over the x-axis and rotating 299° clockwise can be calculated using the distance formula.

The diameter of a circle was 9 cm and the diameter of the final circle was 81 cm. What is the scale factor?

The scale factor can be calculated by dividing the diameter of the final circle by the diameter of the original circle.

Given:
Diameter of the original circle = 9 cm
Diameter of the final circle = 81 cm

Scale Factor = Diameter of final circle / Diameter of original circle
Scale Factor = 81 cm / 9 cm
Scale Factor = 9

Therefore, the scale factor is 9.

The hypotenuse of a triangle was 8 cm and the hypotenuse of the final triangle was 1.6 cm. What is the scale factor?

To find the scale factor, we can use the formula:

Scale Factor = Length of final hypotenuse / Length of original hypotenuse

Given:
Length of original hypotenuse = 8 cm
Length of final hypotenuse = 1.6 cm

Scale Factor = 1.6 cm / 8 cm
Scale Factor = 0.2

Therefore, the scale factor is 0.2.
