Answer:
The measure of arc BC is 96 degrees
Step-by-step explanation:
we know that
The inscribed angle is half that of the arc it comprises.
so
![m\angle BAC=\frac{1}{2}[arc\ BC]](https://tex.z-dn.net/?f=m%5Cangle%20BAC%3D%5Cfrac%7B1%7D%7B2%7D%5Barc%5C%20BC%5D)
we have
substitute
![48^o=\frac{1}{2}[arc\ BC]](https://tex.z-dn.net/?f=48%5Eo%3D%5Cfrac%7B1%7D%7B2%7D%5Barc%5C%20BC%5D)
With respect to the <em>parent</em> function y = cos x, we have these function according to the order of the graphs:
- cos x
- cos (1/2)x
- cos 4x
- cos 2x
- cos (1/4)x
<h3>How to find the functions corresponding to each graph based on the period of a function</h3>
Mathematically speaking, cosines are <em>periodic</em> functions and period (T) is the distance in the <em>horizontal</em> axis such that f(t + T) = f(t). The period of the <em>parent</em> <em>cosine</em> function is 2π. Period in <em>daughter</em> functions may vary by means of the following form:
y = cos Ax (1)
Where:
- x - Independent variable
- y - Dependent variable
- A - Period width
Please notice that <em>daughter</em> functions report periods <em>longer</em> than in the <em>parent</em> function for 0 < A < 1 and a <em>shorter</em> one for A > 1. In consequence, these functions appear in the following order:
- cos x
- cos (1/2)x
- cos 4x
- cos 2x
- cos (1/4)x

If your asking what the price of something is, that was originally 29.99, and has been marked down by 33.33%, the easy way to do this is to take 30 and multiply it by 1/3, resulting in 20. The proper way is to take your calculator and multiply 29.99 by 0.333, resulting in roughly 9.98, meaning the price you pay is 20.00. Either way, your still going to pay $20 for the item.
2 over 3 plus 5 equals 5 and 2 over 3
