Judging by the question I generated the equation y=75(1.09^x)
x is the amount of years.
So the equation you should get for 10 years is y=75(1.09^10)
The answer you get should get is $177.55
Well 41 divided by 6 is 6.8333333333333 so you just need to subtract .833333333333
I hope this answered your question
1.679 kg * (40 min)/(kg) + 20 min = 67.16 min + 20 min = 87.16 min
If i'm correct, the answer should be
-3a
hope this helped! 8)
Answer
The triangle in the figure 4 is correct .
Reason
by using the trignometric identity

Thus


Now in the figure (1)


on simplify

thus side length measures in the figure (1) is not correct .
Now in the figure (2)

thus side length measures in the figure (2) is not correct .
Now in the figure (3)

thus side length measures in the figure (3) is not correct .
Now in the figure (4)

Therefore the figure (4) is correct triangle has side length measures that could be correct
Hence proved
