Answer:
A
Step-by-step explanation:
Because if your going to divide a whole the whole number needs to be 3/1 so it A the mistake
According to the empirical rule, approximately 68% of data fall within 1 standard deviation of the mean.
Answer:
the answer is incomplete, below is the complete question
"Reparametrize the curve with respect to arc length measured from the point where t = 0 in the direction of increasing t. (Enter your answer in terms of s.) r(t) = 3ti + (1 - 4t)j + (1 + 2t)k r(t(s)) ="
answer

Step-by-step explanation:
The step by step procedure is to first determine the differentiate the given vector function
r(t) = 3ti + (1 - 4t)j + (1 + 2t)k

since s(t) is the arc length for r(t), which is define as

if we substitute the value of r'(t) we arrive at


substituting the value of t in to the given vector equation we have
