Answer:
7.2
Step-by-step explanation:
The amplitude is half the difference between the maximum and the minimum.
A = (7.7 − (-6.7)) / 2
A = 7.2
Answer:
11n²
Step-by-step explanation:
Given
= × ×
= 11 × × n²
= 11n²
Step-by-step explanation:
1) first eliminate constant(number without variable) you eliminate constant by doing the inverse operation(if constant is being added, then subtract)(if constant is being subtracted, then add it)
ex: if x+9=32
subtract 9 from both sides to get rid of it
x=23
2) if there is another constant but this constant is being multiplied/divided then do the opposite operation to remove it
you could multiply by 3 on both sides:
x+9=69
x=60
54 is a common denominator between 1/6 and 1/9
