Answer:
Problem 1: No
Problem 2: Yes
Step-by-step explanation:
Problem 1:
{(-2, 1), (-2, 3), (0, -3), (1, 4), (3, 1)}
This relation is not a function because there are two y-values, 1 and 3, related to one x-value, -2.
Thus, for a relation to be a function, every x-value must be related to exactly 1 y-value.
Problem 2:
{(0, 2), (3, 4), (-3, -2), (2, 4)}
In this relation, each x-value (domain) has exactly one y-value (range) that it is related to. Therefore, this is a function.
Answer:
294 in.²
Step-by-step explanation:
I believe this figure is a rectangular prism.
------------------------------------------------------------------------------------
<u>Explain:</u>
To find the surface area of a rectangular prism, use this formula:

or




A phrase I use to help remember this formula is:

------------------------------------------------------------------------------------
<u>Solve:</u>
The length of this rectangular prism is 9 in.
This width is 10 in.
The height is 3 in.
Now, I will plug the numbers into the first formula.

------------------------------------------------------------------------------------
<u>Conclude:</u>
I, therefore, believe the area of this rectangular prism is 294 in.²
37 + 57 = 57 + 37
