Two ladders AB and PQ are resting against opposite walls of an alley. The ladders AB and PQ we 2m and 6m above the ground respectively and T is the point where the two ladders meet. Given that ∆TBP is similar to ∆TAQ, find an expression, in terms of y, for the lenght of PA.

The function y= x - 4x+ 5 approximates the height, y, of a bird, and its horizontal distance, x, as it flies from one fence post to another. all distances are in feet. complete the square to find and interpret the extreme value (vertex). select two answers: one extreme value and one interpretation.
