Answer:
the answer is B because it has only one unknown and also it is a linear equation so it will have only one answer which is (2 )
by the double angle identity for sine. Move everything to one side and factor out the cosine term.
Now the zero product property tells us that there are two cases where this is true,
In the first equation, cosine becomes zero whenever its argument is an odd integer multiple of
, so
where
which occurs twice in the interval
for
and
. More generally, if you think of
as a point on the unit circle, this occurs whenever
also completes a full revolution about the origin. This means for any integer
, the general solution in this case would be
and
.
3x9=27
21/3 = 7
so
7+27x9+5
27x9=243
243+7+5
answer is 255
Answer:
30x25/100
25%=7,5$
30+7,5$=37,5$
The original price was 37,5 because you had to first find out what was 25% in $ to then do the opposite of a sale since we are finding the original price so we have to add it to 30$ since 30$ was the price after the sale.
Hope this helps, have a good day!
