Answer:
Step-by-step explanation:
55 LRD = 1 USD
100 LRD = 1 CHD
Answer:
110 s
Step-by-step explanation:
Divide the given distance by the constant speed
3300/30 = 110 s
This leaves us with the time it took the vehicle to travel the given distance. By dividing m by m/s the measurement of m, or meters, cancels out leaving s, or seconds.
I found this on Yahoo answers 18 different sets.
There are 6 faces, so that's 6 sets.
If we draw two parallel diagonals on two opposite faces, their endpoints are another set of four coplanar points. There are 3 pairs of opposite faces, and each has two such sets of diagonals, giving us another 6 sets.
Now consider the four diagonals of the cube. They all meet at a single point in the center of the cube. Therefore, any pair of them represent a pair of intersecting lines and so define a plane. So any pair of these diagonals produces yet another set of four coplanar vertices.
There are four such diagonals, and there are
4C2 = 4! / (2! 2!) = 4 * 3 / 2 = 6 different combinations comprised of two of them, so that's another 6.
That gives us a total of 18 different such sets of four coplanar vertices of the cube. No other combinations of four vertices are coplanar.
Answer:
det(A) = (-6)(-2) - (-4)(-7)
Step-by-step explanation:
The determinat of the following matrix:
![\left[\begin{array}{ccc}a&b\\c&d\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Da%26b%5C%5Cc%26d%5C%5C%5Cend%7Barray%7D%5Cright%5D)
Is given by: Determinant a*d - b*c
In this case, a=-6, b=-7, c=-4 and d=-2.
Therefore the determinant is: (-6)(-2) - (-7)(-4).
Therefore, the correct option is the third one:
det(A) = (-6)(-2) - (-4)(-7)
