To calculate the area of the shaded part formed from the intersection of the the two circle A and B, we shall proceed as follows:
Calculate the area of one of the overlapping sectors, the subtract the area of its triangle to find the area of the segment, and multiply this by 2.
Answer: D]
X/32 = 80/100
^to solve use cross products
32 x 80 = 2560
2560 ÷ 100 = 25.6
$32 + $25.60 = $57.60

Answer: D) Both a relation and a function</h3>
=======================================================
Explanation:
A relation is any set of (x,y) points usually with some rule tying them together. Though that rule doesn't have to be present. We could simply have a set of points. The set of points we are given is a relation.
A function occurs when we don't repeat the x value. Visually if we had two points stacked on top of each other, then we wouldn't have a function since it fails the vertical line test. A function happens when all x inputs leads to exactly one y output. If we had say { (-4,0), (2,-6), (-4,3) } then this wouldn't be a function since x = -4 repeats itself.
Since none of the x values repeat themselves in our given set, this means we have a function.
Side note: Any function is a relation, but not the other way around.
Answer:
-1/16, 1/32, and -1/64.
Step-by-step explanation:
Basically, all you have to do is find the pattern in the sequence in front, which in this case is division by -2. Hence, you can apply this onwards to get (1/8) / -2 = -1/16, (-1/16) / -2 = 1/32, and (1/32) / -2 = -1/64.
Hope this helped! Merry Christmas!
