We’ve shown that matrix multiplication is generally not commutative, meaning that as a general rule for two
ValentinkaMS [17]

Answer:

a) Observe that

G=\left[\begin{array}{ccc}2&6\\4&0\end{array}\right] =2\left[\begin{array}{ccc}1&3\\2&0\end{array}\right] =2F

Then, FG=F(2F)=2FF, \text{ and } GF=(2F)F=2FF

b) The zero matrix satisfies that for every matrix B such that the product is well defined, 0B=0=B0.

Since the matrix G is the zero matrix then FG=F0=0F=GF

c) The identity(Id) matrix satisfies that for  that for every matrix B such that the product is well defined Id*B=B=B*Id. Observe that G is the identity matrix, then FG=F*Id=F=Id*F=GF

d) Observe that

G=\left[\begin{array}{ccc}3&0&0\\0&3&0\\0&0&3\end{array}\right] =3\left[\begin{array}{ccc}1&0&0\\0&1&0\\0&0&1\end{array}\right] =3Id.

Then GF=3Id*F=3F\\FG=F(3Id)=3F*Id=3F

A regular hexagon has 18 sides calculate the size of each interior
Liula [17]

Answer:

160 °

Step-by-step explanation:

An alternative method is to use the exterior angle.

the sum of the exterior angles is ALWAYS 360 °

So you can find the size of the exterior angles of a regular polygon quite easily:

If there are 18 sides ( n = 18 ) , then each exterior angle is:

\frac{360}{n} =\frac{360}{18} = 20°

The sum of the exterior and interior angles is 180° because they are adjacent angles on a straight line.

∴ each interior angle is 180° - 20° = 160°
