Which function represents a reflection of f(x) = three-sevenths(2)x over the x-axis?
g(x) = –three-sevenths(2)x
g(x) = three-sevenths(–2)x
g(x) = three-sevenths (one-half)–x
g(x) = seven-thirds(2)–x

From the top of a tree a bird looks down on a field mouse at an angle of depression of 50°. if the field mouse is 40 meters from the base of the tree, find the vertical distance from the ground to the bird's eyes.
