Given:
The matrix is ![[-8]](https://tex.z-dn.net/?f=%5B-8%5D)
.
To find:
The determinant of given matrix, i.e, 
.
Solution:
If a matrix is A of order 
, then the value of the determinant of that matrix is equal to the element of that matrix.
For example: Let A be the matrix of order .
![A=[a]](https://tex.z-dn.net/?f=A%3D%5Ba%5D)
Then,
The given matrix is . So, the determinant of given matrix, i.e, , is
Therefore, the value of determinant of given matrix is -8.
It's asking you to work out how many minutes it will take to drive to a school if you're driving at a speed of 35 miles per hour (mph).
But there's a problem with the question because it doesn't tell you how far away the school is.
But this is how you are supposed to do it:
Distance ÷ 35 = answer (in hours)
Answer (in hours) × 60 = Final answer (in minutes).
It's like this because time = distance ÷ speed, and the question asks for the answer in minutes, but the unit is in miles per hour, so you multiply by 60 to get the answer in minutes.
Hope I helped :)
R= s+k/5 this is the answer
Answer:
750
Step-by-step explanation:
Pick one of the schools as the host. There are C(5, 2) ways to select the two representatives from that school and C(5, 1) ways to pick a representative from each of the other schools. So once we have selected a host school, there are 10*5*5=250 ways to pick the representatives. However, any of the three schools can be the host, so we need to multiply 250 by 3 to get 750 ways.
