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
 
        
        
        
Answer: 18.125 lbs
Explanation: The baby weighed 18.125 pounds at the end of eight months. 
The baby weighed 7.25 lbs at birth. Eight months later, he weighed 2.5 or 2½ times its birth weight. Multiply 7.25 by 2.5  (which equals 18.125).
So now eight months later, he's 18.125 pounds.
 
        
                    
             
        
        
        
Answer:
469.42 ft²
Step-by-step explanation:
          w/sin27 = 38/sin40
                    w = sin27*38/sin40
                     w = 26.84 ft
             ∡X = 180 - 27- 40 = 113º
               A = 0.5*(26.84)*(38)*sin(113)
              A = 469.42 ft²
