Answer:
a= 20 b= 160 c= 90
Step-by-step explanation:
Based on how 20 is the angle as you can see by the arrow I made the assumption that a is 20 degrees and for c my estimated guess is 90 because if you imagine how many of the 20 degree angle can fit there you get around 80-90 so I made the guess it was option C. I am sorry if this doesn't make sense I tired to understand it I hope you get the answer right. Also enjoy the rest of your day!
a) The <em>compound interest</em> equation is
.
b) There is an approximate loss of $ 987.16.
c) The stock will take approximately 12.979 to decrease by half.
<h3>How to find stock losses by compound interest model</h3>
<em>Compound interest</em> model represents the gain of a deposit as a function of the number of periods and <em>initial</em> amount. The model is represented below:
(1)
Where:
- Initial capital, in monetary units.
- Interest rate.
- Period number.
- Current capital, in monetary units.
Capital decreases in time when <em>interest</em> rate is a <em>negative</em> number. The equation that models the situation is
and the current capital after eight years is:
C = 4250 · 0.9675⁸
C = 3262.84
That represents an approximate loss of $ 987.16.
And the number of periods required to decrease the capital by half is:


㏒ 0.5 = t · log 0.9675
t ≈ 20.979
The stock will take approximately 12.979 to decrease by half.

Answer:
14.13
Step-by-step explanation:
use the radius, 3 squared
so 3 x 3 = 9
9 x 3.14 = 28.26
28.26 / 2 ( because it is a semicircle) = 14.13
