Write a function rule for the area of a triangle whose base is 4 ft more than the height. What is the area of the triangle when its height is 6 ft? A. A = 0.5h2 + 4h; 42 ft2

B. A = 4h − 0.5h2; 6 ft2

C. A = 0.5h2 + 2h; 30 ft2

D. A = 0.5h2 − 2h; 6 ft2

Which approach to the theory-and-research cycle does the following sequence reflect: (1) specific observations suggest generalizations, (2) generalizations produce a tentative theory, (3) the theory is tested through the formation of hypotheses, and (4) hypotheses may provide suggestions for additional observations?

If the ratio of sum of the first m and n terms of an ap is m2 : n2 , show that the ratio of its mth and nth terms is (2m − 1) : (2n − 1).
