"20% off regular price" can be calculated by multiplying the regular price by (1.00-0.20), or 0.80. Thus, the discounted price will be 0.80($120), or $96.
Answer:
Step-by-step explanation:
a² + b² = c²
3.6² + b² = 7.4²
b² = 7.4² - 3.6² = 41.8
b = √41.8
The explicit formula for the geometric sequence
is

Step-by-step explanation:
The formula of the nth term of a geometric sequence is
, where:
- a is the first term of the sequence
- r is the common ratio between the consecutive terms
The geometric sequence of
is 6 , -2 ,
,
, 
∵
= 6
∵ 
∵
= -2
∴ 
- Divide both term by 2 to simplify it
∴ 
∵ 
- Substitute the value of
and r in the rule above
∴ 
The explicit formula for the geometric sequence
is
