Answer:

Step-by-step explanation:
Geometric sequence
Each term in a geometric sequence can be computed as the previous term by a constant number called the common ratio. The formula to get the term n is

where
is the first term of the sequence
The problem describes Georgie took 275 mg of the medicine for her cold in the first hour and that in each subsequent hour, the amount of medicine in her body is 91% (0.91) of the amount from the previous hour. It can be written as
amount in hour n = amount in hour n-1 * 0.91
a)
This information provides the necessary data to write the general term as

b)
In the 8th hour (n=8), the remaining medicine present is Georgie's body is



<h2><u>Complete Question: </u></h2>
Learning Task 1: Identify similar and dissimilar fractions. On your note- book write S if the fractions are similar and D if dissimilar.
1. 
2. 
3. 
4. 
5. 
<h2><em><u>The answers:</u></em></h2>
1.
- Similar (S)
2.
- Similar (S)
3.
- Dissimilar (D)
4.
- Dissimilar (D)
5.
- Dissimilar (D)
Note:
- Similar fractions have the same denominator. i.e. the bottom value of both fractions are the same.
- Dissimilar fractions have different value as denominator, i.e. the bottom value of both fractions are not the same.
Thus:
1.
- They have equal denominator. <u><em>Both fractions are similar (S).</em></u>
2.
- They have equal denominator. <em><u>Both fractions are similar (S).</u></em>
3.
- They have equal denominator. <em><u>Both fractions are dissimilar (D).</u></em>
4.
- They have equal denominator. <u><em>Both fractions are dissimilar (D).</em></u>
5.
- They have equal denominator. <em><u>Both fractions are dissimilar (D).</u></em>
Therefore, the fractions in <em><u>1 and 2 are similar (S)</u></em> while those in <em><u>3, 4, and 5 are dissimilar (D).</u></em>
