PLEASE HELP ASAP!!!
Nonamiya [84]

Answer:

Option C. Yes; y=2x

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form k=\frac{y}{x} or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

so

In this problem

For x=0, y=0

That means ----> the line passes through the origin

<em>Find the value of k</em>

For x=2, y=4

k=\frac{y}{x} ----> k=\frac{4}{2}=2

For x=4, y=8

k=\frac{y}{x} ----> k=\frac{8}{4}=2

The values of k are equal

therefore

The table represent a direct variation

The equation is equal to

y=2x

Which of the following trigonometric ratios has a value that is undefined?
34kurt

Answer:

csc π.

Step-by-step explanation:

csc π  because  csc = hypotenuse / opposite side  and the opposite side = 0. Anything divided by zero is undefined.

Another way to the same conclusion is:  we know that sin π = 0 and csc π = 1 / sin π = 1 / 0  which is indeterminate.
