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
Answer:
slope is 1/8
Step-by-step explanation:
you have to substitute the values of x and y into the equation below:
after simplifying your answer would be 1/8
Answer: positive association and linear association
Step-by-step explanation:
59.9 = 23.2 + 17.1 + 2*leg = Perimeter
2 * leg = 19.6
each leg = 9.8 meters
Let S = spoon
Let K = knife
1 knife is thee times the cost of a spoon, so it would be 3S
Now you have 9S + 12K = 82.80
We can replace the K with 3S:
9S +12(3S) = 82.80
Simplify the left side:
9S + 36S = 82.80
Add:
45S = 82.80
Divide both sides by 45"
S = 82.80 / 45
S = 1.84
One spoon cost $1.84
We know one knife cost 3 times as much, so multiply the cost of a spoon by 3:
Knife = 1.84 x 3 = $5.52
