Answer:
The integral
is 0.
Step-by-step explanation:
A parameterization of curve C can be:
X (t) = cost 0 <= t <= pi
Y (t) = sint 0 <= t <= pi
r (t) = costi + sintj
r '(t) = -sinti + costj
![Fds = [-costsin^3t + sintcos^3t] dt](https://tex.z-dn.net/?f=Fds%20%3D%20%5B-costsin%5E3t%20%2B%20sintcos%5E3t%5D%20dt)
The integral
is given by:
![\int _0^{\pi }\left[-costsin^3t + sintcos^3t dt\right]dt](https://tex.z-dn.net/?f=%5Cint%20_0%5E%7B%5Cpi%20%7D%5Cleft%5B-costsin%5E3t%20%2B%20sintcos%5E3t%20dt%5Cright%5Ddt)

A and D have a lower rate than 1/3.
Answer:
4500
Step-by-step explanation:
10000 x .09 x 5
slope-intercept formula: y = mx + b
m = slope
b = y-intercept
your equation: y = 4/3x - 3
m = 4/3
b = -3
so, the answer would be the last option.
hope this helps, have a great day/night :)
Since 1 milligram = 0.001 grams you just have to multiply 75 milligram by 0.001 grams in order to get the grams.
75 x 0.001= 0.075 grams so the answer is F.
