An observation deck extends 311 feet out above a valley. The deck sits 261 feet above the valley floor. If an object is dropped from the observation deck, its height h in feet, after t seconds, is given by h= - 162 +261. How long will it take for the object to be 5 feet above the valley floor?
It will take seconds for the object to be 5 feet above the valley floor.
(Type an integer or a decimal)

answer: okw

step-by-step explanation:

i think it is c, not positive though

step-by-step explanation:

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5

step-by-step explanation:

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
