In ANOP, the measure of ZP=90°, NP = 9, PO = 40, and ON = 41. What ratio represents the secant of ZN?

Acyclist bike x distance at 10 miles per hour .and returns over the same path at 8 miles per hour.what is the cyclist average rate for the round trip in miles per hour ?

Assume that y varies inversely with x. if y=1.6 when x=0.5 find x when y=3.2

Answer asap! show all work! find the number of complex roots, the possible number of real roots and the possible rational roots of the polynomial function. then, solve for all roots. x^3 + 2x^2 + 3x + 6 = 0
