The answer is A) -23

A is a 1x3 Matrix while B is 3x1 Matrix. Since A has the same number of rows as that of the number of columns of B, they can be multiplied. A has 1 row and B has 1 column. So, their products is a 1x1 Matrix. 
Simply, the operation is:
(3)(-1) + (-2)(4) +(6)(-2) = -23

Which expression represents the series 1+5+25+125+625
solong [7]
So if you want to find the nth term so
1st term=1
2nd term=5
3rd term=25
we notice that 5^1=5 and 5^2=25 , but they are on the second ones so
the expression is

the nth term=5^(n-1)
so 1st term=5^(1-1)=5^0=1
2nd term=5^(2-1)=5^1=5
3rd term=5^(3-1)=5^2=25
and so on


the expression is 5^(n-1)

In the last two years, Mari grew 2 1/4 inches, Kim grew 2.4 inches, and Kate grew 2 1/8 inches. Write the amounts they grew in o
Gennadij [26K]
First, let's turn the fractions into decimal form so you can see the answer, more clearly. 
2 \frac{1}{4} = 2.25
2.4 = 2.4
2 \frac{1}{8} = 2.125

Now, after looking at the decimals, we can see which decimals are the biggest. They would order, from least to greatest, like this. 
1)  2.4
2) 2.25
3) 2.125

I hope this helps!
