She will need to sell about 28 or 27 sweaters per month. It's between the two. Hope i helped :D
Step-by-step explanation:
One of the equations of ellipse is in a form of the lengths of its axes. If we have the length of its major axis as 2a and the length of its minor axis as 2b then, the values of a and b are,
2a = 16, a = 16/2 = 8
2b = 4, b = 4/2 = 2
Given that we have the major axis as vertical, the equation for ellipse is,
y²/a² + x²/b² = 1
Substituting,
y²/8² + x²/2² = 1
Simplifying,
y² + 16x² = 1
Answer: y² + 16x² = 1
Hope this helped and if it did please give me brainliest, it will help me a lot. :)
Have a good day!
