Answer:

<h2>D. the sum of the distances to each focus equals a certain constant.</h2>

Step-by-step explanation:

In mathematics, an elipse is defined as a curve which surrounds two focal points. The relation between the two focal points and a points on the curve is what defines an elipes, which is "the sum of the two distances to the focal points is a constant".

Therefore, the right answer to this question is D, because that's the defintion of an elipse.

Answer:

Option D is correct.

Step-by-step explanation:

The relationship between any point on an ellipse and each of its foci is:

The sum of the distances to each focus equals a certain constant. The constant will be 2a

If d₁ and d₂ are the distances then their sum is d₁ + d₂ = 2a.

Option D is correct.

A sporting goods manager was selling a ski set for a certain price. The manager offered the markdowns shown on the right, making

Answer:

The original selling price would be $ 515.87 ( approx )

Step-by-step explanation:

Consider the complete question is :

"A sporting goods store manager was selling a ski set for a certain price. The manager offered the markdowns shown, making the one-day sale price of the ski set $325. Find the original selling price of the ski set. It was marked down 10% and 30%"

Suppose x be the original selling price ( in dollars ),

After marking down 10%,

New selling price = x - 10% of x = x - 0.1x = 0.9x

Again after marking down 30%,

Final selling price = 0.9x - 30% of 0.9x

= 0.9x - 0.3 × 0.9x

= 0.9x - 0.27x

= 0.63x

According to the question,

0.63x = 325

$\implies x =\frac{325}{0.63}=\$ 515.87$

Therefore, the original selling price would be $ 515.87.
