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
Answer:
She has a 10% chance.
Step-by-step explanation:
To make this easier on our selves let's divide each by 2.
That makes Lucy hold 10 tickets for the 100 tickets available.
10/100 = 10%
Any numerator that is over 100 is the percentage
Say if I had 52/100 I would have 52%
