Answer:
8x-13x²-3
Step-by-step explanation:
you first have to work with the negative sign and the brackets by multiplying the negative sign by everything in the second brackets
3x-5-7x²+2-6x²+5x
then group the like terms
3x+5x-7x²-6x²+2-5
8x-13x²-3
I hope this helps
I THINK the answer is 6000 square feet because each one is 6 square feet and you have 1000 of them so 6 square feet times 1000 squares is 6000 square feet.
I think it’s 2/8-4 hopefully that’s helps
Answer:
C. 20
Step-by-step explanation:
Take a value from the x-axis (Width) and the y-axis (Height) and substitute them into the equation. I'll use the point (5, 4).
Height = Constant/Width
4 = Constant/5 (Given)
20 = Constant (Multiplied 5 on both sides)
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)
