Answer:
<em><u>$4.59</u></em> would be a good estimate for the dessert with 10% tax.
Step-by-step explanation:
10% = 0.10
0.10 + 4.49
84
If DA bisects angle CAE, and angle DAE=42
Then Angle CAE=84
If line AC bisects BAE, and we know angle CAE=84
Angles CAE and BAC are equal meaning they both measure 84 degrees
Answer:
A) x²/25 + y²/9 = 1
Step-by-step explanation:
The major axis length is the sum of distances to the foci from the ellipse, 10. So the semi-major axis has length 10/2 = 5. The foci are on the x-axis, so the ellipse is oriented horizontally.
The semi-minor axis is the other leg of the right triangle having the focus and center as one leg, and the semi-major axis as the hypotenuse. This is obviously a 3-4-5 triangle, so the semi-minor axis length is 3.
When the ellipse is horizontal, the formula for it is ...
... (x/(semi-major axis))² + (y/(semi-minor axis))² = 1
... (x/5)² + (y/3)² = 1
... x²/25 + y²/9 = 1

-1 ≤ 2-j < -5
Subtract 2 from all 3 terms in the inequality:
-1 -2 ≤2-j-2 < -5-2
Simplify:
-3 ≤ j < -7
This inequality cannot be be solved. There is no solution.
