This is an arith. sequence, and the common difference is -9.
a(n+1) = a(n)-9, with a(1)=8. Thus, if we look at the first term, we see 8; subracting 9 from 8 produces the second term (-1).
False, 2 is greater than -5 by 7
-5 + 7 = 2

Answer:
12.5 feet
Step-by-step explanation:
how to:
lets find the angle that corresponds with the 10 foot side.
to do that we add 50 degrees plus 90 degrees (right angle) to get 140 degrees.
as we know, a triangles angles will total 180 degrees, so 180 - 140 = 40 degrees for the angle corresponding to the 10 foot side.
put these into ratios:
<u>Angle A </u> = <u>Angle B</u>
side a side b
now plug in our numbers:
<u>50 degrees</u> = <u>40 degrees</u>
X 10 feet
Cross multiply:
50 (10 feet) = 40 (x)
solve for x:
500 = 40 (x)
500/40 = x
12.5 = x

This is perhaps the most odd math question I have ever come across. Anyhow -
#1 - Positive, because smoking increases the chance of having lung cancer. (though technically there is not a linear relationship between the two as people do in fact receive lung cancer even when having not smoked)
#2 - No relationship. (Though one could argue a student may text more when given more free time as a consequence of having spent less time at school, but this is wholly subjective and unable to be substantiated by logic.)
#3 - Negative, due to the mass of the tootsie pop decreasing with each lick.
Of course, I am assuming when you say "positive" and "negative" you are speaking in terms of numbers or addition and subtraction rather than "positive" or "negative" socially.
