20 POINTS When an alternating current of frequency fand peak current lo passes through a resistance R, then the power delivered to the resistance at time t seconds is P = ZoRsinº2 5ft
Write an expression for the power in terms of cos 2 sett.

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

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.
