The positive integers v, w, x, y, and z satisfy the equation v+(1/w+/1/(x+1/(y+1/z))).
Compute 10^4v+10^3w+10^2x+10^1y+10^0z.

Which statement about the graph of y = 8(0.25)^2

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?
