1. A 40 ft. ladder is leaning against a building. The ladder forms a 70° angle with the ground. How far is the bottom of the ladder from the base of the building?

If t17 = 3 (t5) in an arithmetic progression, find t1 in terms of d.

Ab and bc are tangent to circle d. find x is ab = 3x + 8 and bc = 26. find x

Identify the function that contains the data in the following table: x     -2         0         2         3         5     f(x)     5         3         1         2         4     possible answers: f(x) = |x| + 1 f(x) = |x - 2| f(x) = |x - 2| - 1 f(x) = |x - 2| + 1
