Answer:
Below.
Step-by-step explanation:
is also 
It will differ for any x besides 1 and 0 because you're multiplying x by itself, which makes the answer greater.
But, it's the same for 1 and 0 because they equal each other when you square them.
Using ur calculator you should get 15 degrees ( Use the sin-1 key.).
Angle complementary to x is 90-15 = 75 degrees
and as sin x = cos(90-x) then cos 75 is also equal 0.2588
Answer:
92 feet and each animal has 2 feet so divide by 2 = 46
then minus it by 33 the number of heads and get 13
<u>answer is 13 animals</u>

Answer:
Step-by-step explanation:
Given the set notations A = {a} B = {b, c} C = {a, b, d}
BUC = {a, b, c, d}
B∩C = {b}
a) A × (BUC) = {aa, ab, ac, ad}
b) A × (B ∩ C) = {ab}
c) (A × B) ∪ (A × C)
A × B = {ab, ac} and A × C = {aa, ab, ad}
(A × B) ∪ (A × C) = {aa, ab, ac, ad}
d) For (A × B) ∩ (A × C)
(A × B) ∩ (A × C) = {ab}
Note that the union (U) of two sets is the combination of all the elements in both sets while the intersection (∩)of two sets is the common elements that are found in both sets.
The Cartesian product of two sets is derived by mapping each of the element in the first set with all the element in the other set. It is denoted by the multiplication sign.
