Answer:
1/x^24
Step-by-step explanation:
(x^-6/x^2)^3 multiply the powers inside the parenthesis by power outside of the parenthesis to get rid of parenthesis
x^-6×3/x^2×3 = x^-18/x^6
subtract the denominator's power from nominator's power
x^-18-6 = x^-24 ➡ 1/x^24
Answer:

Step-by-step explanation:





Answer:
A(t) = π(8t)²
Step-by-step explanation:
Radius of a circular wave increases by 8 cm each second.
Every second radius of circular wave so the sequence of increase in radius will be,
8, 16, 24, 32.........(8t)
Here 't' = time
Since, area of a circle = πr²
Therefore, area of the circular wave after 't' seconds since the wave begins,
A(t) = π(8t)²
Answe the awnser is b
