Answer:
<u>yes it is 16%</u>
Step-by-step explanation:
Let the price be $100 then new price will be = $100+$45= $145
45/100*100= $45
A 20% decrease means 20% 0f $145
20/100 * 145= $29
the new price after 20% decrease will be $ 145- $ 29= $ 116
$116-$100= $16
$16/100*100= 16%
yes it is 16%

Answer:
i got 20
sorry if this is wrong
Step-by-step explanation:
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
