Answer: Two regular octagons and eight congruent rectangles
Step-by-step explanation:
An octagon has 8 sides and the shapes on the bottom of the shape are 8 rectangles.
Answer:
2x^4−11x^3+7x^2+5x−3
Step-by-step explanation:
The ^ means exponent
If
and
, separate variables in the differential equation to get
![e^{-y} \, dy = \sin(x) \, dx](https://tex.z-dn.net/?f=e%5E%7B-y%7D%20%5C%2C%20dy%20%3D%20%5Csin%28x%29%20%5C%2C%20dx)
Integrate both sides:
![\displaystyle \int e^{-y} \, dy = \int \sin(x) \, dx \implies -e^{-y} = -\cos(x) + C](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cint%20e%5E%7B-y%7D%20%5C%2C%20dy%20%3D%20%5Cint%20%5Csin%28x%29%20%5C%2C%20dx%20%5Cimplies%20-e%5E%7B-y%7D%20%3D%20-%5Ccos%28x%29%20%2B%20C)
Use the initial condition to solve for
:
![-e^{-0} = -\cos(-\pi) + C \implies -1 = 1 + C \implies C = -2](https://tex.z-dn.net/?f=-e%5E%7B-0%7D%20%3D%20-%5Ccos%28-%5Cpi%29%20%2B%20C%20%5Cimplies%20-1%20%3D%201%20%2B%20C%20%5Cimplies%20C%20%3D%20-2)
Then the particular solution to the initial value problem is
![-e^{-y} = -\cos(x) - 2 \implies e^{-y} = \cos(x) + 2](https://tex.z-dn.net/?f=-e%5E%7B-y%7D%20%3D%20-%5Ccos%28x%29%20-%202%20%5Cimplies%20e%5E%7B-y%7D%20%3D%20%5Ccos%28x%29%20%2B%202)
(A)
Wait cam u explain ? 5 times 4/9 then you divide by 7
B. Complementary means totaling 90 degrees, and supplementary means totaling 180 degrees.
