Relatively Prime: Two integers are said to be relatively prime if there is no integer greater than one that divides them both.

(a): Factorization of 15 is

Since 5 is the common factor in factorization of both the numbers, therefore they are not prime numbers.

(b): Factorization of 29 is

and the factorization of 58 is

Since 29 is the common factor in factorization of both the numbers, therefore they are not prime numbers.

(c): Factorization of 40 is

and the factorization of 63 is

Since in the factorization of both the numbers, there is no common number than one, thus 40 and 63 are prime numbers.

(d): Factorization of 261 is 2

and the factorization of 513 is

Since 3 is the common factor in factorization of both the numbers, therefore they are not prime numbers. Thus, the pair 261 and 513 are not relatively prime.

A red ball anda green ball are simultaneously tossed into the air. The red ballis given an initial velocity of 96 feet per second, and itsheight tseconds after it is tossedis $16{t}^{2}96t$ feet. The green ball is given an initial velocity of 80feet per second, and its height t seconds after it is tossed is $16{t}^{2}80t$ feet.a)Find a polynomial D(t) thatrepresents the difference in the heights of the two balls.

b) How muchhigher is the red ball 2 seconds after the balls are tossed?

I have no idea how to goabout this. If anyone can explain how to do this and give solutionI would be very greatful.
