144
1,728 divided by 12 is 144
Area is not a unit of measure. Foot and Yard are US customary units. Meter is the correct answer.
Let's analyse the function

The amplitude is A, so we want A=1.5
Now, we start at x=0, and we have 
After one second, i.e. x=1, we want this sine function to make 330 cycles, i.e. the argument must be 
So, we have

so, the function is

Answer:
x = 4
Step-by-step explanation:
2(x/4 + 8) = 18
First: Distribute 2 into "x/4 + 8".
2x/4 + 16 = 18
2x/4 = 18 - 16
1x/2 = 2
x/2 • 2 = 2 • 2
x = 4
P.S "•" means to multiply.
