because that angle is a little less than half of 90 so 42 is the best answer
Part (a)
<h3>
Answer: Ø</h3>
This is the empty set
------------------
Explanation:
It doesn't matter what set A is composed of. Intersecting any set with the empty set Ø will always result in the empty set.
This is because we're asking the question: "What does some set A and the empty set have in common?". The answer of course being "nothing" because there's nothing in Ø. Not even the value zero is in this set.
We can write Ø as { } which is a set of curly braces with nothing inside it.

Part (b)
<h3>Answer: {1,2,3,4,5,6}</h3>
-----------------
Explanation:
When you union the universal set with any other set, you'll get the universal set.
The rule is where I've made B the universal set to avoid confusion of the letter U and the union symbol which looks nearly identical.
Why does this rule work? Well if an item is in set , then it's automatically in set U (everything is in set U; it's the universe). So we're not adding anything to the universe when applying a union involving this largest set.
It's like saying
- A = set of stuff inside a persons house
- = set of stuff outside a persons house (ie stuff that is not in set A)
- U = set of every item
we can see that will basically form the set of every item, aka the universal set.
I’m not sure if the answer is correct but what I did was 9 times 1 is 9 so what then I did was 9 divided by 88=9.79
Answer:
$13,000 at 7% and $12,000 at 4%
Step-by-step explanation:
Use formula:
where
I = interest,
P = principal,
r = rate (as decimal),
t = time (in years)
<u>7% rate:</u>
P = $x
r = 0.07
t = 1 year
Then
<u>4% rate:</u>
P = $(25,000 - x)
r = 0.04
t = 1 year
Then
If he receives an annual return of $1,390, then
so
