Determine whether the following curve uses arc length as a parameter. if not, find a description that uses arc length as a parameter. r(t) = (4t^2,8t^2, root 89t^2), for 1 leq t leq 4 r(t) does not use arc length as a parameter. a description of the curve that uses arc length as a parameter is r(s) = (type exact answers, using radicals as needed.)

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

answer: the slope is equal -1.
