If
is the common difference between terms in the sequence
, then
...
You're told that
(the sum of the first 16 terms in the sequence, presumably). Well, we know that
Recall that
so that we have
So we get
Finding the X-intercept.
1.) Solve for x by substituting 0 in for y.
4x+(0)=5
4x/4+5/4
x=1.25 or 1 and 1/4.
a=1/4pid^2
4a=pid^2
4a/pi=d^2
square both sides to get d
Answer: Square root of 4a over pi equals d.
2500 is 40% of the 100%
so, from the 40%, figure out 10%
2500/4=600
600 x 6=3,600
so, 3,600 is the answer
