If f = (1, 2), (2, 3), (3, 4), (4, 5),
g = (1, -2), (3, -3), (5, -5), and
h = (1, 0), (2, 1), (3, 2),

find the following and state the domain:

f / h

From the top of a bldg. 60ft high, two observers are seen on the ground. The angle of depression to the two observer are 54 degrees and 24 degrees. If the two observers and the bldg. are standing on horizontal ground and if the two observers are on the same side of the bldg. how far are the observers from each other?
I need your help how to illustrate and solve it.

Two points, A and B, lie on a horizontal plane directly east of a building 35 meters high. The angles of elevation to the points are 29 degree and 10 minutes and 43 degree and 50 minutes,respectively. Determine the distance between the two points.

Graph the given function using the given values of x. Also use the graph to determine the domain and range of the function.
