2. Corey spies a bald eagle in a tall tree. He estimates the height of the tree to be 80 feet and the angle of elevation to the

bird from where he stands to be 68°. The leaves on the tree make it difficult for Corey to watch the bird, so he takes several steps away from the tree to get a better view. He now estimates his angle of elevation to be 41°.
How many feet did Corey step back to gain a better view of the bird? Round your answer to the nearest hundredth of a foot

The sample at option B, {0, 2} is not a part of the sample space of a spinner when spun two times.

<h3>What is a sample space?</h3>

The set consists of all the possible outcomes of an event called sample points, which is said to be a sample space.

<h3>Calculation:</h3>

It is given that,

a spinner has 5 sections of equal area and each section is numbered from 1 to 5.

If the spinner is spun two times, then the possible outcomes are 25. They are:

{(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (5, 1), (5, 2), (5, 3), (5, 4), (5, 5)}

So, from the given options, the sample {0, 2} is not possible since there is no such a section on the spinner named 0.

F(x)=3x-8
iVinArrow [24]
What this is asking is for you to plug values into the following function:f(x)=\frac{3x-8}{6x}

Since the question is asking you to find f(3)-f(1), this is how you work it out:
You take the function;
f(x)=\frac{3x-8}{6x}
And plug the numbers indicated in for x;
f(x)=\frac{3x-8}{6x}\\&#10;f(3)=\frac{3(3)-8}{6(3)}\\&#10;f(3)=\frac{9-8}{18}\\&#10;f(3)=\frac{1}{18}\\\\&#10;f(1)=\frac{3(1)-8}{6(1)}\\&#10;f(1)=\frac{3-8}{6}\\&#10;f(1)=\frac{-5}{6}\\\\&#10;Now\ what\ you\ do\ is\ you\ subract\ f(3)\ and\ f(1).\\&#10;f(3)-f(1)\\&#10;f(3)-f(1)=\frac{1}{18}-\frac{-5}{6}\\&#10;f(3)-f(1)=\frac{1}{18}-\frac{-15}{18}\\&#10;f(3)-f(1)=\frac{1+15}{18}\\&#10;f(3)-f(1)=\frac{16}{18}=\frac{8}{9}
So the answer to f(3) - f(1) = \frac{8}{9}
