Answer:
15.47
Step-by-step explanation:
Since the four is in the hundrenths place you use the digit to the right of it, and if the number is greater than 5 you add one more. Thus the answer being 15.47
Although it's a bit more logical for it to be a smaller measurement, it's likely 5g

Answer:
Common ratio, r=-3
Recursive Formula
Step-by-step explanation:
The formula for the geometric sequence: 
is given as:
<u>Common Ratio</u>
Dividing the next terms by the previous terms, we obtain:
Therefore, the common ratio of the sequence, r=-3
<u>Recursive Formula</u>
We observe that the next term, 
is obtained by the multiplication of the previous term. f(n-1) by -3.
Therefore, a recursive formula for the sequence is:
The length of a in the triangle to the nearest tenth is 8.1 units.
<h3>How to find side of a triangle?</h3>
The side a of the triangle can be found using cosine formula.
Therefore,
a²= b² + c² - 2bc cos A
a² = 10² + 12² - 2 × 10 × 12 cos 42°
a² = 100 + 144 - 240cos 42
a² = 244 - 178.354758115
a = √65.6453
a = 8.10217871933
a = 8.1
