Answer: 32
Step-by-step explanation:
When the set has <em>n</em> elements, the power set has 
elements. This also gives us the cardinality of the power set, which is what we are looking for.
A = {2,3,9,7,5}
(1) 2
(2) 3
(3) 9
(4) 7
(5) 5
<em>n</em> = 5
32
Answer:
all three angles should add up to 180 so subtract what you know from 180 and you should be able to find everything from there
You have two people answer and whoever answer you think is better you can mark them as brainliest
the points (-6,0)(-2,0)(1,0)(3,0) all exist in the graph which is only correct for the second graph to make your self even more sure
since the zeros are given and it ia a polynomial you can figure out the facrored form
which will yield
f(x)=(x+6)(x+2)(x-1)(x-3)
conducting a simple sign test
------------------------------------------'
there will be 4 critical values
-6 -2 1 3
before -6 the sign of f(x) -*-*-*-= +
after -6 and before -2 the sign of f(x) +*-*-*-=-
after -2 and before 1 the sign of f(x) +*+*-*-=+
after 1 and before 3 the sign of f(x) +*+*+*-=-
after 3 the sign of f(x) +*+*+*+=+
which only fits the upper right graph
