An elevator goes up, at a rate of 750 feet per minute. is the height to which the elevator ascends proportional to the number of minutes it takes to get there

Yes. Proportions are pretty much “if X increases, Y also increases corresponding to X.”
In other words, the more time it ascends, the higher it will go. The greater height it ascends, the more time it took to get there.

If it were to ascend for 5 minutes, it would get to a greater height than if it were to ascend for only 3 minutes.

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
