Answer:
7.5 metres
Step-by-step explanation:
The formula for the area of a parallelogram is Area = base x height.
In the problem, you are given the base, which is 9.44 metres, and the area, which is 70.8 square metres.
When you plug everything into our area formula, you should get:
70.8 = 9.44 x height
To solve for height, you would divide both sides by 9.44.
70.8 ÷ 9.44 = height
7.5 = height
Don't forget your units, which is <u>metres</u>!
height = 7.5 metres

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)
