The product that is undefined is known a CD, where C is a 3 x 1 matrix and D is a 1 x 2 matrix.

<h3>What is the matrix about?</h3>

Looking at the product of matrix, note that to multiply the two matrix, the column of the first matrix needs to have the same or equal to the row of the 2nd matrix.

And in this case (propensity), it is not satisfied by the first option because:

C = 3 x 1 and

O= 2 x 1 matrix

In this case CD is therefore undefined.

So we can say that The product that is undefined is known a CD, where C is a 3 x 1 matrix and D is a 1 x 2 matrix.

Find the amount paid for the loan.<br><br> $2000 at 12% for 3 years

Free_Kalibri [48]

They paid $720

Here's why:
The formula to this is Interest = Principal x Rate x Time or i = prt
Principal = $2000
Rate = 12%
Time = 3 years
2000 x .12 x 3 = i PEMDAS
2000 x .12 = 240
240 x 3 = 720
i = $720

how to find the volume of each sphere, both in terms of \pi and the nearest tenths for r=3 use 3.14 for \p.

icang [17]

Volume formula of a sphere:
$\frac{4}{3}$ $\pi$ r³

given:
r = 3

V = $\frac{4}{3}$ $\pi$ (3)³
V = $\frac{4}{3}$ × 27 $\pi$
V = 36 $\pi$ units³ (in terms of $\pi$ )
V = 113.097 units³ ≈ 113.1 units³

What is the value of x in the equation 2(x−3) 9=3(x 1) x? x = −3 x = −1 x = 0 x = 3

Masja [62]

The solution of the linear equation is x = 0.

<h3>What is the linear equation?</h3>

An equation is a mathematical statement, which has an equal sign (=) between the algebraic expression.

Linear equations are the equations of degree 1.

The given linear equation is;

$\rm 2(x-3)+ 9=3(x+ 1) +x$

The value of x is determined in the following steps given below. $\rm 2(x-3)+9=3(x+1)+x\\\\2x-6+9=3x+3+x\\\\\ 2x+3=4x+3\\\\3-3=4x-2x\\\\0=2x\\\\x=0$
