For something to be a function there can only be one x value for every y value (meaning x can’t repeat). To see if the graphs are functions you need to perform the vertical line test. This is where you scan an imaginary line across the graph and if the line passes through two points at the same time, that graph is not a function. This would mean that for the graphs, only graph B is a function. For the mapping part, if an x value has more than two lines attached to it, it’s not a function. This means that mapping A is a function because it only had one line for every x value whereas mapping B had x value 5 with two lines instead of one. For the table, it’s a function if the x value isn’t repeated. This means that table B is a function because no x value repeats whereas in table A the x value 2 repeats twice. That leaves graph A, mapping B, and table A as ‘not a function’. Hope this helped.
The dimension of the above figure is 9ft×3ft×6ft The home work wants you to recognize where the length, width , and height of the prism. the length runs along the base, the width is the smallest side on this figure, and the height always runs up and down. All the answers below should be circled:
3ft×6ft×3ft
9ft×6ft×1ft
9ft×3ft×3ft does not apply because 6 factored by a third is 2 not 3.
Answer: 397
Step-by-step explanation:
8x8=64
3x3=9
18x18=324
324+64+9= 397
Thanks for the question!
4 - 6 + 6
We can make this easier by doing it one step at a time. First, lets do 4 - 6.
4 - 6 + 6
-2 + 6
Now, solve:
-2 + 6
4
Hope this helps!
Answer: 
Step-by-step explanation:
The acceleration 
of the satellite can be calculated by the following equation:
Where:
is the final speed of the satellite
is the initial speed of the satellite (it was "stationary" before the release)
is the time
Isolating :
Finally:
