A pendulum is L meters long. The time, t, in seconds that it takes to swing back and forth once is given by =t2L. Suppose the pendulum takes 7.76 seconds to swing back and forth once. What is its length? Carry your intermediate computations to at least four decimal places, and round your answer to the nearest tenth.

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is symmetric about the line y = 120,000.

step-by-step explanation:

3100

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
