Answer:

C- y=2|x+2|

Step-by-step explanation:

When the number is inside the absolute value bars, the value shifts- so a positive two would move left two, and a negative two would move right two. If the number was outside of the equation, the shape would move up or down- a positive two would move the shape up two, and a negative two would move the graph down two.

An ellipse has a center at the origin, a vertex along the major axis at (0, 17), and a focus at (0, −8).
MAVERICK [17]

Answer:

The last one.

Step-by-step explanation:

The standard form equation of an ellipse with foci on the y-axis is ...

  y²/a² +x²/b² = 1

where "a" and "b" are the lengths of the semi-major and semi-minor axes, respectively. If "c" is the distance from the center to the focus, then this relation also holds:

  b² +c² = a²

For this ellipse ...

  b² + 8² = 17²

  289 -64 = b² = 225 . . . . . subtract 8²

  b = 15 . . . . . . . . . . . . . . . . . take the square root

The equation of the ellipse is then ...

  y²/17² +x²/15² = 1

sveta [45]
I think you have a typo in your problem. I believe you are asking about 29% of the circle. 

In that case, it would by 29% of 360 or 0.29 x 360 = 104.4

29% is not the same as 29 degrees.
