Answer:
Option C. Anna and Sara
Step-by-step explanation:
<u><em>The complete question in the attached figure</em></u>
Let
h ----> the minimum height h in inches necessary to ride a certain roller coaster
we have
The solution for this inequality is the interval [48,∞)
so
The value of h must be greater than or equal to 48 inches
<u><em>Verify who can ride the roller coaster</em></u>
1) Miguel 42 in
substitute the value of h in the inequality
----> is not true
therefore
Miguel can't ride the roller coaster
2) Patrick 45 in
substitute the value of h in the inequality
----> is not true
therefore
Patrick can't ride the roller coaster
3) Anna 48 in
substitute the value of h in the inequality
----> is true
therefore
Anna can ride the roller coaster
4) Sara 52 in
substitute the value of h in the inequality
----> is true
therefore
Sara can ride the roller coaster

Answer:
Step-by-step explanation:
A recursive formula is a formula in which each term is based on the previous term.
In a geometric sequence, each term is found by multiplying the previous term by a constant.
To get from 27 to 9, then from 9 to 3, etc., we would multiply by 1/3. This makes the common ratio 1/3.
The recursive formula for a geometric sequence is
, where
represents the general term,
, represents the previous term, and r represents the common ratio.
Plugging in our values, we have
We also have to indicate what the first term, a₁, is. In this sequence, it is 21. This gives us
