When plucked, the high E string on a guitar has a frequency of 330 cycles per second. What sine function represents this note wh

Ber [7]

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

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

What equation represents the parabola with focus (-1,4) and directrix y= -2

Llana [10]

Answer:

Hello

y=(x+1)/12 +1

Step-by-step explanation:

$\text{As the directrice is horizontal:}\\\\\\y=-2 ==> k=-2\\\\Focus=(a,b)=(-1,4)\\\\\boxed{y=\dfrac{x-a}{2(b-k)} +\dfrac{b+k}{2} }\\\\\\y=\dfrac{x+1}{2(4+2)} +\dfrac{4-2}{2} }\\\\\boxed{y=\dfrac{x+1}{12} +1}\\$
