Not quite sure sorry edit : Oh sorry I supposed to add this in the comment section
the volume of a prism is v=ahh, where b is the base and h is the height. The base of the prism is a rectangle. Multiply the base by the height, and that is the volume.
im pretty sure it's the first option.
Answer:
30
Step-by-step explanation:
For a = <xa, ya> and b = <xb, yb>, the dot product is the sum of products ...
a·b = (xa)(xb) + (ya)(yb)
Substituting the given information, you have ...
a·b = 5·4 + 2·5 = 20 + 10
a·b = 30
_____
Some graphing calculators can do such math. There are also dot product calculators available on the Internet. If you have quite a few of these to calculate, you can put the appropriate formula into a spreadsheet.
The answer is C because It seems to be the most logical answer
