Answer:
I'm sorry you got that wrong. The correct answer was R since it is staying in the same place which is called a constant line. It stays in the same place since she isn't moving, she is just standing there waiting for the cab.
Answer:
A
Step-by-step explanation:
Since DA can be considered a line the whole value of it is 180 degrees. So you do 180-105 which equals 75. You then add 75 to 67 which is equal to 142. The value of a triangle is 180 so you would do 180-142 and you would get 38. Thus, X is equal to 38 degrees.
The simplest form is 3/12
Hope this helps.
Binomial theorem:
![(x+1)^{16}=\displaystyle\sum_{k=0}^{16}\dbinom{16}kx^{16-k}1^k=\sum_{k=0}^{16}\dbinom{16}kx^{16-k}](https://tex.z-dn.net/?f=%28x%2B1%29%5E%7B16%7D%3D%5Cdisplaystyle%5Csum_%7Bk%3D0%7D%5E%7B16%7D%5Cdbinom%7B16%7Dkx%5E%7B16-k%7D1%5Ek%3D%5Csum_%7Bk%3D0%7D%5E%7B16%7D%5Cdbinom%7B16%7Dkx%5E%7B16-k%7D)
The
![x^5](https://tex.z-dn.net/?f=x%5E5)
term corresponds with the term in the sum for which
![16-k=5\implies k=11](https://tex.z-dn.net/?f=16-k%3D5%5Cimplies%20k%3D11)
. For this
![k](https://tex.z-dn.net/?f=k)
, we get
![\dbinom{16}{11}x^{16-11}=\dbinom{16}{11}x^5](https://tex.z-dn.net/?f=%5Cdbinom%7B16%7D%7B11%7Dx%5E%7B16-11%7D%3D%5Cdbinom%7B16%7D%7B11%7Dx%5E5)
So the coefficient you want to find is
