Answer:
24.08 cm
Step-by-step explanation:
a²+b²=c²
16²+18²=c²
256+324=c²
580=c²
24.08=c
Hey there Kia!
![\left[\begin{array}{ccc}40/2=20 \ ; \ 19/2=9.5\end{array}\right]](https://tex.z-dn.net/?f=%20%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D40%2F2%3D20%20%5C%20%3B%20%5C%2019%2F2%3D9.5%5Cend%7Barray%7D%5Cright%5D%20)
Your answer should look like the following.
![\left[\begin{array}{ccc} \frac{19}{20y}= \frac{9.5}{40y^3} \end{array}\right]](https://tex.z-dn.net/?f=%20%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D%20%5Cfrac%7B19%7D%7B20y%7D%3D%20%5Cfrac%7B9.5%7D%7B40y%5E3%7D%20%20%5Cend%7Barray%7D%5Cright%5D%20)
Hope this helps you!
Answer:
A proportional relationship is any relationship that stays constant. since both sides of the equation do not change, this is a proportional relationship
<span>1. It will not be spread out horizontally across the entire coordinate plane because in Step 4, Nancy selected an incorrect scale on the axis. This is true (though I wouldn't have used the word "incorrect") but the "incorrectness" is relatively small.</span>
<span>2. It will not be spread out vertically across the entire coordinate plane because in Step 5, Nancy selected an incorrect scale on the y-axis. This is true and the "incorrectness" is relatively large. </span>
<span>3. It will not be spread out horizontally across the entire coordinate plane because in Step 2, Nancy plotted time instead of temperature on the axis. This is plain nonsense!</span>
<span>4. It will not be spread out vertically across the entire coordinate plane because in Step 3, Nancy plotted temperature instead of time on the y-axis. This is also plain nonsense!</span>
<span>So, of the options on offer, I think 2. best describes the graph</span>
