Answer:
I agree
Step-by-step explanation:
Yes
Choice A) This is false. Arc AC is 180 degrees while arc AB is 90 degrees.
Choice B) This is true. These segments are radii
Choice C) This is true. AB is 90 degrees and so is BC.
Choice D) This is true due to Thales Theorem.
--------------------------------------------------------------------
The only answer choice that is false is choice A.
Therefore, the final answer is choice A
Using a geometric sequence, it is found that:
a) The explicit formula is: .
b) The value of her collection 9 years after she started tracking is of $94,557,148.
<h3>What is a geometric sequence?</h3>
A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.
The nth term of a geometric sequence is given by:
In which is the first term.
Item a:
Three years ago, her collection was worth $250,000, hence the first term is .
In two years, the collection was valued at $1,102,500, hence the common ratio is:
.
Hence, the explicit formula is:
Item b:
The value of her collection 9 years after she started tracking is of $94,557,148.

Answer:
n+12 <4
Step-by-step explanation:
Answer: the option A. 23.1%
Explanation:
1) You are given the formula:
<span>Mark up rate on selling price = markup rate cost / (1+ markup rate on cost)
</span>
2) You are given the markup rate cost: 30% = 0.30
3) Then, you just have to replace the value in the formula:
<span>Mark up rate on selling price = 0.30 /(1+ 0.30) = 0.30 / 1.30 ≈ 0.2308
</span><span>
</span><span>
</span><span>To pass to percent just multiply by 100: 0.2308 × 100 = 23.08% ≈ 23.1%
</span><span>
</span><span>
</span><span>And that is the answer.
