I don’t understand how to do #6

katrin2010 [14]

A={0,2,4,6}, C={1,3,5,7}

A∩C, means that we need to find the same number in A and C. We can see that there are no the same numbers in set A and set C,

so A∩C=∅, empty set of numbers.

BU(A∩C)

"U" means that set will include all numbers of the set B and set (A∩C). Because A∩C=∅, empty set of numbers, (A∩C) does not have any numbers, so

BU(A∩C) includes only numbers of the set B.

So, BU(A∩C)={1,2,3,4,5}.

Answer is {1,2,3,4,5}.

What is the rate of change between the interval of x = 0 and x = pi over two?

bekas [8.4K]

Answer:

The answer is $\frac{4}{\pi }$

Step-by-step explanation:

Given the graph as shown, we have to find the rate of change between the interval of x=0 and $\frac{\pi }{2}$ .

To find the rate of change we have to find the slope which is given by

$Rate\thinspace of \thinspace change=slope=\frac{change\thinspace\thinspace in\thinspace\thinspace y\thinspace\thinspace coordinate}{change\thinspace\thinspace in \thinspace\thinspace x \thinspace\thinspace coordinate}$

= $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

= $\frac{5-3}{\frac{\pi }{2} }$

= $\frac{4}{\pi }$
