Step-by-step explanation:
2.50x=1.50x+50
.50x=50
÷.50
X=100
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
![n[/tex ]is any integer.\\Meanwhile,\\[tex]10\sin x-3=0\implies\sin x=\dfrac3{10}](https://tex.z-dn.net/?f=n%5B%2Ftex%20%5Dis%20any%20integer.%5C%5CMeanwhile%2C%5C%5C%5Btex%5D10%5Csin%20x-3%3D0%5Cimplies%5Csin%20x%3D%5Cdfrac3%7B10%7D)
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
.

Answer:
77 inches
Step-by-step explanation:
Given
1 inch = 3 miles in map
We are also given the actual distance between City A and City B = 231 miles.
In order to get the distance in inches = Distance between City A and City B in miles/ 3
We are dividing the distance by 3 to get the distance in inches.
So,
Distance on map = 231/3
= 77 inches
