the answer is c: .... 72+8w
First, find the increase in charge between the two station. That is:
$4.12-$4.00=$0.12
Then, divide the increase by the price charged by Gas Station X.
$0.12/$4.00=0.03
Lastly, since it is a decimal, transform it to percentage by multiplying 100%
0.03x100%=3%
Hope this is the brainliest answer.
I think it D cause 30(cos(30x)+14=-16
Your dividing by 30
your 180 (which is degrees) is
radians. As the cosine function is periodic with period 2 we get
4 x 3 = 12
12 would be the answer
