A direct variation equation takes the form y=kx, where k is a constant.

Choice A displays a direct variation since it takes the form y=kx, where k=5.

Choice B does NOT display direct variation because x is in the denominator. This relationship between x and y in choice B is called inverse variation.

Choice C displays direct variation since it takes the form y=kx, where k=0.7

Choice D displays direct variation since it takes the form y=kx, where k=1/9.

In conclusion, your answer is CHOICE B. Have an awesome day! :)

Answer:

The maximum variance is 250.

Step-by-step explanation:

Consider the provided function.

$V(x)=1000x(1-x)$

$V(x)=1000x-1000x^2$

Differentiate the above function as shown:

$V'(x)=1000-2000x$

The double derivative of the provided function is:

$V''(x)=-2000$

To find maximum variance set first derivative equal to 0.

$1000-2000x=0$

$x=\frac{1}{2}$

The double derivative of the function at $x=\frac{1}{2}$ is less than 0.

Therefore, $x=\frac{1}{2}$ is a point of maximum.

Thus the maximum variance is:

$V(x)=1000(\frac{1}{2})-1000{\frac{1}{2}}^2$

$V(x)=250$

Hence, the maximum variance is 250.

Does this set of ordered pairs represent a function? Why or why not? {(–1, 5), (0,-3), (2,7), (4,0), (7, 5)}

Kisachek [45]

Yes, it does. Because these points do respect the "law" that for each "x" there is only one "y" that corresponds to it
