Abc is a right triangle with right angle c. ab = 18 cm m what is bc round answer to nearest tenth

Write an explicit formula that represents the sequence defined by the following recursive formula:

An arrow is shot vertically upward at a rate of 180ft/s. use the projectile formula h=−16t2+v0t to determine at what time(s), in seconds, the arrow is at a height of 420ft. round your answer(s) to the nearest tenth of a second.

Which of the following is the explicit rule for a geometric sequence defined a recursive formula of a -5a for which the first term is 23?
