Answer:
Situation B is a function.
Step-by-step explanation:
We know that,
A function is a relation in which every element in the domain i mapped to a unique element in the co-domain.
<em>That is, every element in the domain must have a unique image.</em>
So, we see that,
Situation A = {student's name, all the colors that the student likes}
Here, the students can have more than one color which they like.
Thus, this relation is not a function.
Situation B = {student's name, the student's favorite math teacher}
Here, the students can have only one favorite math teacher.
So, this relation is a function.
Answer:
180 Square Feet
Step-by-step explanation:
For Rectangle:
l = 9 ft
b = 20 ft
Area of Rectangle
![= l \times b \\ = 9 \times 20 \\ = 180 \:square \: feet](https://tex.z-dn.net/?f=%20%3D%20l%20%5Ctimes%20b%20%5C%5C%20%20%3D%209%20%5Ctimes%2020%20%5C%5C%20%20%3D%20180%20%5C%3Asquare%20%5C%3A%20%20feet)
Power Property because log
![\sqrt[3]{x}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7Bx%7D%20)
= log
![x^{ \frac{1}{3} }](https://tex.z-dn.net/?f=%20x%5E%7B%20%5Cfrac%7B1%7D%7B3%7D%20%7D%20)
= (1/3)logx;
