Polynomials are linear combinations of positive integer powers. For example,
is a polynomial, but
is not.
(In case you're unfamiliar with the term, a linear combination of two quantities is the sum of scaled versions of those quantities, e.g. a general linear combination of 
and 
is 
, where 
are any numbers.)
is not a polynomial; the offending term is 
, or 
.
Answer:
-0.5 is the answer I think
Answer:
Step-by-step explanation:
Dividing both sides by -7.
There is only one solution that satisfies the equation.
Answer:
86.5 ns
Step-by-step explanation:
The speed in the original direction (horizontally) is unchanged by the vertical force the field exerts. The travel time is ...
time = distance/speed = (4.5×10^-2 m)/(5.20×10^5 m/s) = 8.65×10^-8 s
_____
An engineer would express this time using the SI prefix nano- for 10^-9. The time is 86.5 ns.
The answer is c. You can plug in the values for x and y and see which ones equal up to 5!
