The length, width, and height of a rectangular prism is a, (a-13), and (a+13) respectively, which statement best describes (a-13
1 answer:
Answer:
a. The width of the rectangular prism is 13 units less than the length.
Step-by-step explanation:
From the information given we know that
a = length of rectangular prism and
= width of rectangular prism
An expression like means that we need to subtract 13 units from the length to obtain the width of the rectangular prism.
Therefore,
The width of the rectangular prism is 13 units less than the length.

Answer:
The Recursive Formula for the sequence is:
; a₁ = 125
Hence, option D is correct.
Step-by-step explanation:
We know that a geometric sequence has a constant ratio 'r'.
The formula for the nth term of the geometric sequence is
where
aₙ is the nth term of the sequence
a₁ is the first term of the sequence
r is the common ratio
We are given the explicit formula for the geometric sequence such as:
comparing with the nth term of the sequence, we get
a₁ = 125
r = 1/5
Recursive Formula:
We already know that
- a₁ = 125
- r = 1/5
We know that each successive term in the geometric sequence is 'r' times the previous term where 'r' is the common ratio.
i.e.
Thus, substituting r = 1/5
and a₁ = 125.
Therefore, the Recursive Formula for the sequence is:
; a₁ = 125
Hence, option D is correct.
