Answer:
W÷9=z
Step-by-step explanation:
18÷9=2
45÷9=5
81÷9=9
Z is the quotient of W when divided by 9.
Find a ∩ b if a = {2, 5, 8, 11, 14} and b = {1, 3, 5, 7}. {1, 2, 3, 5, 7, 8, 11, 14} {5}
Maslowich
The intersection of given set a and b is a∩b = {5}.
According to the given question.
We have two sets a and b.
a = {2, 5, 8, 11, 14}
And, b = {1, 3, 5, 7}
As, we know that "the intersection of two sets A and B is the set of all those elements which are common to both A and B. Symbolically, we can represent the intersection of A and B as A ∩ B".
Since, only the element which is common to set a and set b is 5.
Thereofore, the intersection of given set a and b is given by
a∩b = {5}

Answer:
the answer should be C.
Step-by-step explanation:
When two straight lines intersect each other at 90˚ or are perpendicular to each other at the intersection, they form the right angle. A right angle is represented by the symbol ∟.
Answer:
D. 
Step-by-step explanation:
We have been given an image of a circle. We are asked to find the measure of arc WX.
Upon looking at our given diagram, we can see that angle S is formed by intersecting secants outside the circle.
We will use intersecting secants theorem, which states that measure of an angle formed by two intersecting secants outside a circle is half the difference of intercepted arcs.
Using above theorem, we can set an equation to find the measure of arc WX as:
Therefore, the measure of arc WX is 32 degrees and option D is the correct choice.
