Although the question's print is not clear, to the best of my knowledge, as I can see, We are given that:

r(x)=-x^5 and s(x)=2x^3

No, we know that, by definition:

(r.s)(x)=r(x)\times s(x)

\therefore (r.s)(x)=-x^5\times 2x^3=-2x^8

Thus, for the functions r and s which are defined for all real numbers x, the answer to the question asked is:

(r.s)(x)=-2x^8

How do I determine the 50th term for the sequence <br> -5, -1, 3, 7, 11
Mademuasel [1]
The sequence is going up by 4 so u have to multiply each term by four and the -5 is it’s 0th term as well it’s beginning so you have to input that in the equation as well
4(50) - 5 = 200 - 5 = 195
I’m not very good at explaining so I hope u get it
