Answer: The relation represents y as a function of x, because each value of x is associated with a single value of y. (B)

Step-by-step explanation:

The relation definitely represents y as a function of x, so we can already eliminate two of the answers that say it does not represent. (It does not repeat)

There is one x value paired with one value of y. There isn't two values of x paired with one value of y.

Therefore, our answer is B, The relation REPRESENTS y as a function of x, because each value of x is associated with a SINGLE value of y.

Step-by-step explanation:

$\cos(a) + 2 \cos(a + 240)$

$\cos(a) + 2 \cos(a) \cos(240) - \sin(a) \sin(240)$

$\cos(a) + 2( - \frac{ \cos(a) }{2} + \frac{ \sqrt{3} }{2} \sin(a) )$

$\cos(a) - \cos(a) + \sqrt{3} \sin(a)$

$\sqrt{3} \sin(a)$

If you graph the new identity, and the og identiy, they will be conciding graphs, so they are the same identity.

F(x) = square root 32x <br> g(x) = square root 2x

otez555 [7]

Given:

The two functions are:

$f(x)=\sqrt{32x}$

$g(x)=\sqrt{2x}$

To find:

The $(f\cdot g)(x)$ . Assume $x\geq 0$ .

Solution:

We have,

$f(x)=\sqrt{32x}$

$g(x)=\sqrt{2x}$

Now,

$(f\cdot g)(x)=f(x)\cdot g(x)$

$(f\cdot g)(x)=\sqrt{32x}\cdot \sqrt{2x}$

$(f\cdot g)(x)=\sqrt{32x\times 2x}$

$(f\cdot g)(x)=\sqrt{64x^2}$

$(f\cdot g)(x)=8x$

Therefore, the correct option is A.
