Let's analyse the function

y = f(x) = A\sin(\omega x)

The amplitude is A, so we want A=1.5

Now, we start at x=0, and we have 1.5\sin(0)=0

After one second, i.e. x=1, we want this sine function to make 330 cycles, i.e. the argument must be 330\cdot 2\pi

So, we have

f(1)=1.5\sin(\omega) = 1.5\sin(660\pi)

so, the function is

f(x) = 1.5\sin(660\pi x)

If the parallelogram floor needs a base of 16 feet,what will the height of the floor be
nydimaria [60]

Answer:

See Explanation

Step-by-step explanation:

<em>The question is incomplete because the area of the parallelogram is missing. However, the following will guide you in answering the question</em>

Given

Base = 16\ ft

Required

Determine the Height

Area of a Parallelogram is:

Area = Base * Height

Make Height the subject

Height = \frac{Area}{Base}

Substitute 16 for Base

Height = \frac{Area}{16}

This implies that you divide the value of area by 16 to get the height of the parallelogram.

Take for instance;

Area = 64ft\²

The height would be

Height = \frac{64}{16}

Height = 4\ ft

Or

Area = 80ft\²

The height would be

Height = \frac{80}{16}

Height = 5\ ft
