Find the measurement of d please!

Answer:
Given the information in the diagram, the measurement of <em>d </em> is 5m.
Step-by-step explanation:
In the diagram, we know that the two triangles are similar to each other meaning their segments have equal ratios. We are already given the measurements of two segments. Let's find the ratio.
8 : 4
This can also be written as...
2 : 1
Now, we can find the measurement of <em>d </em>by using this ratio.
Cross - multiply.
= 5
So, the measurement of <em>d </em> is 5m.

Answer:
Step-by-step explanation:
All the relations are not functions. We can determine ( identify ) whether a relation is function or not by drawing a vertical line intersecting the graph of the relation. This is called vertical line test.
- If the vertical line intersects the graph of a relation at one point , the relation is a function .
- If it cuts at more than one point , it is not a function. It means that if there are more points of the graph of a relation of a vertical line , same first component ( pre - image ) has more images ( second component ) which is not the function by definition.
--------------------------------------------------
Let's check all of the options :
☐ Option A :
- The vertical line cuts the graph at two points. So , the graph does not represent a function.
☐ Option B
- No! This is also not a function as the vertical line cuts the graph at two points.
☐ Option C
- Nah! This too can't be called a function as the vertical line cuts the graph at two points.
☑ Option D
- Yep! The vertical line cuts the graph at one point. Thus , the graph represents a function.
Yayy!! We found our answer. It's ' Option D '.
