You're first one is correct, with the increase of Petroleum being the most at 3.4%
However, the second one is incorrect, because you are finding the percentage increase, or 12.7 - 9.3 = 3.4%
So the second one is 3.4
hope this helps
Answer:
it is sin C
Step-by-step explanation:
Sinα=h/L
α=arcsin(h/L)° we are told that h=18 and L=20 so
α=arcsin(9/10)°
α≈64° (to nearest whole degree)
0=(9k-6)+33 9*-2/3=-6/1
-33=(9k-6) subtract 33 from both sides
-27=9k add 6 to both sides
-3=k divide both sides by 9
i think this is the answer hopefully it helps
