<span>y=-3cos(2pi/5 x)
y=a cos (bx+c) +d
a=-3; b=2pi/5; c=0; and d=0
Period: P=2pi/b
P=2pi/(2pi/5)
P=2pi*[5/(2pi)]
P=(2pi*5)/(2pi)
P=5
Answer: T</span><span>he period of the sinusoid given by y=-3cos(2pi/5 x) is 5.</span>
The simplified answer is x = 1/3
Can't it just be like if for every 2cm is 8 feet
Then 6cm is 24feet
And 4cm = 16
