12x²-8x-15 should be your answer
F = 15%
v = 5%
0.15f + 0.05v = 0.14*10
15f + 5v = 140
3f + v = 28
f + v = 10 (total volume)
---------- Subtract
2f = 18
f = 9 liters of 15%
v = 1 liter of 5%
i think its d! hope that helps! is that flvs?
Answer:
sec A= 1.01 and cot B =8.25
Step-by-step explanation:
Given :
sec A and cotB if a =8 and b=7
Now,
=
and

Therefore, answer will be sec A= 1.01 and cot B =8.25
(3/5 )*2000 would give you 1200, which is your answer
