By analyzing the piecewise function, we conclude that the first graph is the correct one,

<h3>Which of the following is the graph of the piecewise function?</h3>

The first part of the piecewise function is:

f(x) = √(-x - 2) for x ≤ -2

This parts ends at:

f(-2) = 0

With that, we can discard the last two graphs.

Now, the second part is a rational function with a negative coefficient.

Because of that sign, when x is positive, the function tends to negative infinite near in the asymptote, while when x is negative, the function tends to positive infinite in the asymptote.

Because of that, we conclude that the correct option is the first graph.

Using the rational root theorem, it is found that your friend is correct.

<h3>What is the rational root theorem?</h3>

It is a theorem that states that for a polynomial with integer coefficients, with q being the factors of the leading coefficient and p being the factors of the constant, every <u>possible rational root</u> is the format $\frac{p}{q}$ .

In this problem:

The leading coefficient is 1, hence it's only factor is $q = 1$ , thus guaranteeing that every possible rational zero is an integer, which means that your friend is correct.

Find the angle measure to the nearest degree. <br> cos A = 0.7431<br> How do I do this?

svet-max [94.6K]

Answer:

Step-by-step explanation:

If you are looking for a missing angle measure, you use the 2nd button and the cos button. Make sure, first off, that your calculator is in "degree" mode by hitting the "mode" button and making sure that the "degree" is highlighed and not the "radian". Then hit "clear". Once you know that you are in the correct mode, hit "2nd" then "cos" and you will see this on your screen:

$cos^{-1}($

Inside the parenthesis you will enter your decimal, so it looks like this now:

$cos^{-1}(.7431$

You do NOT have to close the parenthesis, but you can if you want to. Then hit "enter" to get that the angle that has a cosine of .7431 is 42.0038314 or, to the nearest degree, 42
