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.
Answer:
No
Step-by-step explanation:
<u>Use synthetic division</u>
-5 | 1 -4 3 7
____<u>-5 45 -240</u>
1 -9 48 | -233
Since the remainder is not 0, then x+5 is not a factor of the polynomial
Use the least common denominator (LCD) to write these fractions as equivalent fractions with like denominators, and then compare them two at a time
