Answer:
No solution
Step-by-step explanation:
This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by 2 gives the next term. In other words, <em>a n +a1 ⋅ r n -1</em><em> </em>
Geometric Sequence:<em> </em><em>r = 2</em>
The series given has a value of<em> </em><em>r </em>such that <em>r > 1 or
r < − 1.</em> Therefore, the infinite sum cannot be calculated.<em>

Answer: <em>time = 55.48 years</em>
Explanation:
Given:
Principal amount = $10000
Interest rate = 2% p.a
Amount = $30000
We can evaluate the time taken using the following formula:
Solving the above equation, we get
Now taking log on both sides, we get;
<em>time = 55.48 years</em>
13 + -30 = -43 I think that's it
Answer:
B. 29.7
Step-by-step explanation:
All you have to do is find the area of the half circle (r² × 3.14 × ½) and subtract that from the initial area of the rectangle ( 9×4 ) After doing that it gives you 29.7ft².
