Answer:
Option (1).
Step-by-step explanation:
In the figure attached, original parallelogram(in red) has been reduced by a scale factor 'k' forming a new parallelogram (in blue).
We know scale factor is the ratio of one side of the image (dilated figure) and the corresponding side of the original figure,
Scale factor =
k =
k =
Therefore, scale factor will be .
Option (1) will be the answer.

Answer:
a.)x² + y² = 900
b.)y = √900 - x²
Step-by-step explanation:
P.S - The exact equation is as follows :
As given,
The shape of the roller coaster is a half of a circle. Center the circle at the origin and assume the highest point on this leg of the roller coaster is 30 feet above the ground.
a.)
Equation of circle be x² + y² = r²
As given , leg of the roller coaster is 30 feet above the ground.
⇒ r = 30
⇒x² + y² = 30²
⇒x² + y² = 900
∴ we get
Equation of height of Roller coaster - x² + y² = 900
b.)
As we have, x² + y² = 900
⇒y² = 900 - x²
⇒y = √900 - x²
