Jon watches his sister Jessica skateboard. When she jumps and launches herself into the air with an initial speed of v0 feet per second, her path in terms of time, t, in seconds, is represented by these equations.
Equation 1 x t v0tcos
Equation 2 y t v0tsin 16t2
The first equation models the horizontal distance, x t , that the skateboarder travels, and the second equation models the vertical height, y t , that the skateboarder attains.

Write and evaluate an expression for Jon's height above the launch and landing ramps after 0.5 second. Round your answer to the nearest tenth.
