If matrix a has dimensions 2 x 4 and matrix b has dimensions 1 x 4, can these matrices be multiplied?
yes or no

No, This matrices cannot be multiplied.

Step-by-step explanation:

If Matrix A has dimensions 2 x 4 and Matrix B has dimensions 1 x 4.

Dimension of matrix A = 2 x 4

Dimension of matrix B = 1 x 4

Multiplication rule.

Two matrices can only be multiplied when row number of one matrix equal to column number of other matrix.

In this case only 4 is common but both of them are column numbers. So these matrices cannot be multiplied.

No, This matrices cannot be multiplied.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
