Triangle ABC has vertices A(1, 3), B(−2, −1), and C(3,−2). After going through the following glide reflection, find the coordinates for A′′, B′′, and C′′.
Reflection: across x-axis

Rotation: 90° about the origin

The maximum distance (in nautical miles) that a radio transmitter signal can be sent is represented by the expression 1.23h√, where h is the height (in feet) above the transmitter. estimate the maximum distance x (in nautical miles) between the plane that is receiving the signal and the transmitter. round your answer to the nearest tenth.
