Answer:
B. 8 • 8 • 8 • 8 • 8
Step-by-step explanation:
I'm gonna assume you meant 8 to the 5th power, or .
Step 1: <u>Define and explain.</u>
Remember: exponents are simply repeated multiplication.
Exponents tell you how many times to multiply the base number by itself.

Step 2: <u>Solve.</u>
Step 3: <u>Conclude.</u>
Therefore, is the same as
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
