When a rate is written as money per item, a unit rate is called a
tatyana61 [14]

Answer:

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. If you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.

Hopefully this helps!

The graph of F(x) shown below resembles the graph of G(x)- x, but it has been changed somewhat. Which of the following could be
Fudgin [204]

We can solve this question in the following way. Looking at the graph, we see that F(x) is shifted from one unit to the right, and it is represented by | x - 1|. Then, we can multiply this result by 4 to have the final graph, since the graph is not inverted.

Therefore, the answer to this question is F(x) = 4 * | x - 1 |.

Find the value of the trig function indicated ​
Lera25 [3.4K]

Answer:

\cos(\theta)=\frac{4}{5}

Step-by-step explanation:

Step 1:

Let us find the missing side. We know this is a <u>right triangle</u>, so we can use the pythagorean thereom to find the last side. Let us set 12 as variable <em>a</em>, 20 as variable <em>c</em>, and the unknown side as variable <em>b</em>.

a^2+b^2=c^2\\12^2_b^2=20^2\\b^2=400-144\\b^2=256\\b=\pm16

We do know that a <u>length can never be negative</u>, so the side <em>b</em> would be 16.

Step 2:

According to SOHCAHTOA, cosine is utilizes the adjacent and hypotenuse of the given angle theta. Let us write the equation:

\cos(\theta)=\frac{adjacent}{hypotenuse} \\\\\cos(\theta)=\frac{16}{20} \\\\\cos(\theta)=\frac{4}{5}

<em>I hope this helps! Let me know if you have any questions :)</em>
