Answer:
1/7
Step-by-step explanation:
When 2 lines are perpendicular the gradient of one is the reciprocal of the other :
If the gradient of A was 2 the gradient of B would be 1/2.
If the gradient of a is 7 the gradient of b would be 1/7 .
Hope this helped and have a good day
Answer: a) 59049, b) 15120, c) 126.
Step-by-step explanation:
Since we have given that
5 digit sequences from the integers 1,2,...9.
a) the digits can be the same.
Repetition is allowed.
So, Number of ways to form 5 digit sequences would be
![9\times 9\times 9\times 9\times 9\\\\=9^5\\\\=59049](https://tex.z-dn.net/?f=9%5Ctimes%209%5Ctimes%209%5Ctimes%209%5Ctimes%209%5C%5C%5C%5C%3D9%5E5%5C%5C%5C%5C%3D59049)
b) the digits cannot be the same and the order in which they appear matters.
Repetition is not allowed and order is maintained, so we will use "Permutation":
![^9P_5=15120](https://tex.z-dn.net/?f=%5E9P_5%3D15120)
c) the digits cannot be the same and the order in which they appear does not matter.
Repetition is not allowed and order is not maintained, so we will use "Combination":
![^9C_5=126](https://tex.z-dn.net/?f=%5E9C_5%3D126)
Hence, a) 59049, b) 15120, c) 126.
