The b in both of the graph types: y = a sin(bx), y = a cos(bx), affects the period (or wavelength) of the graph. What happens to
the period as the value of b gets larger?

stethere all not eveanp-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.
