An ellipse has a center at the origin, a vertex along the major axis at (0, 17), and a focus at (0, −8). which equation represents this ellipse? answer choices below vvv

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

the answer is simply just 6n add the two together as they have an n

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
