A bridge support is represented by the top half of an ellipse, shown in the figure to the right. The point Q, which is the center of the ellipse, is at the origin. The bridge support is 18 feet high at its center and it is 25 feet from either end of the bridge to the center. Find the equation that best describes the ellipse.

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
