<u>ANSWER: </u>
The equation is y = 1.06x, so option D is correct.
<u>EXPLANATION:</u>
Given:
Amount Catherine is paid for an MP3 player=$159.00
The price paid includes a sales tax= 6%
To find:
Equations that can be used to determine the price of the MP3 player before tax?
Solution:
Now, we know that, total cost = selling price of item + sales tax on item
y = x + 6% of x
y = x +
y = x + 0.06x
y = 1.06x
Hence, the equation is y = 1.06x, so option D is correct.
The distance from the center to where the foci are located exists 8 units.
<h3>How to determine the distance from the center?</h3>The formula associated with the focus of an ellipse exists given as;
c² = a² − b²
Where c exists the distance from the focus to the center.
a exists the distance from the center to a vertex,
the major axis exists 10 units.
b exists the distance from the center to a co-vertex, the minor axis exists 6 units
c² = a² − b²
c² = 10² - 6²
c² = 100 - 36
c² = 64
c = 8
Therefore, the distance from the center to where the foci are located exists 8 units.
