Answer:
D. empty set
Step-by-step explanation:
Each of the operations X-Y and Y-X removes elements that are common to X and Y. The resulting two sets have no elements in common, so their intersection is the empty set.
_____
X -Y = {2, 5, 6}
Y -X = {3, 7, 8}
{2, 5, 6} ∩ {3, 7, 8} = { }
Isolate the trig function and move the rest of the equation to the other side of the equals sign. Then, work backwards to find the angle. From that, you can find the tangent function. This just simplified the equation, so finally, just solve.
Answer:
<h2>9/28</h2>
Step-by-step explanation:
<em><u>2 3/7 - 1 1/4</u></em>
<em><u>2 3/7 - 1 1/4First turn the two mixed numbers into improper fraction:</u></em>
<em><u>2 3/7 - 1 1/4First turn the two mixed numbers into improper fraction:17/7 - 5/4</u></em>
<em><u>2 3/7 - 1 1/4First turn the two mixed numbers into improper fraction:17/7 - 5/4Next find the Lowest Common Denominator:</u></em>
<em><u>L.C.D = 28</u></em>
<em><u>L.C.D = 2821 - 12/28</u></em>
<em><u>L.C.D = 2821 - 12/28= 9/28</u></em>
<u>It won't be a mixed number because the denominator is bigger than the numerator.</u>
Answer:3,366.75
Step-by-step explanation:
3,366.746193889 is what I got then rounded
in a 45-45-90 triangle, the sides are the same
you can find the third side using the pythagoran therum
but a and b are the same thing, so
if x is the side
so, like in problem 1
always make sure the hypotnus is longer than the legs
