Hii please help me! In Cincinnati, fireworks are launched from a large barge on the Ohio River for a Labor Day celebration. Their flight can be modeled by the function h(t) = -4.9(t - 4)^2 + 80, where h is the height in meters and t is the time in seconds.

Suppose that buildings obstruct the fireworks. So, the barge is relocated 30 meters to the east.

Write a function to model the path of the fireworks in the new location.
