We know that
<span>Since the focus and vertex are above and below each other, rather than side by side, I know that this ellipse must be taller than it is wide.
</span>Then
a²<span> will go with the </span>y<span> part of the equation
</span>Also, since the focus is 8 <span>units below the center, then </span><span>c = 8
</span>since the vertex is 17<span> units above, then </span><span>a = 17
</span>The equation b²<span> = a</span>²<span> – c</span>²<span> gives me
</span>b²=17²-8²-----> b²=225
the equation is
y²/a²+x²/b²=1------> y²/289+x²/225=1
the answer isy²/289+x²/225=1see the attached figure
The terms in the sum are given by the sequence

We have

for all
, and the series
clearly diverges, so
must also diverge.
For the answer to the question above, I'll provide a solution below.
52x < = 20,000 - 11200
52x < = 8800
x < = 8800/52
x < = 169.23
So the answer to your question is 169 acres <span>of barley the farmer can plant and still be under budget.
I hope my answer helped you. have a nice day!</span>
