Answer:
![\left[\begin{array}{ccc}2&-3\\1&-4\end{array}\right]=-5](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D2%26-3%5C%5C1%26-4%5Cend%7Barray%7D%5Cright%5D%3D-5)
Step-by-step explanation:
Given:
The given matrix is.
![\left[\begin{array}{ccc}2&-3\\1&-4\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D2%26-3%5C%5C1%26-4%5Cend%7Barray%7D%5Cright%5D)
the determinant of the above matrix is.
![\left[\begin{array}{ccc}2&-3\\1&-4\end{array}\right]=2\times (-4) - (-3)\times 1](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D2%26-3%5C%5C1%26-4%5Cend%7Barray%7D%5Cright%5D%3D2%5Ctimes%20%28-4%29%20-%20%28-3%29%5Ctimes%201)
![\left[\begin{array}{ccc}2&-3\\1&-4\end{array}\right]=-8 - (-3)](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D2%26-3%5C%5C1%26-4%5Cend%7Barray%7D%5Cright%5D%3D-8%20-%20%28-3%29)
![\left[\begin{array}{ccc}2&-3\\1&-4\end{array}\right]=-8 +3](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D2%26-3%5C%5C1%26-4%5Cend%7Barray%7D%5Cright%5D%3D-8%20%2B3)
Therefore, the determinant of the matrix is -5
Answer:
angle 1 is 42
angle 2 is 138
angle 3 is also 42
Step-by-step explanation:
for angle 1, I don't remember what the exact rule was but basically since they are opposite of each other they are equal
for angle 2 all you have to do is subtract 42 from 180 because line n is at an angle of 180 and line m simply splits it into two pieces
for angle 3, I dont remember what the exact rule is or hot to explain it well but it is also 42
Answer:
37.34 or 37 if rounded
Step-by-step explanation:
Write the equation vertically to make it easier. 8 minus 4 equals 4, 5 minus 2 equals 3, 9 minus 2 equals 7, and 6 minus 3 equals 3.
Answer:
$19.74
Step-by-step explanation:
$987 x .02 = $19.74
I think you have a typo in your problem. I believe you are asking about 29% of the circle.
In that case, it would by 29% of 360 or 0.29 x 360 = 104.4
29% is not the same as 29 degrees.
