Suppose that we try to solve the matrix equation AX = B by using an inverse matrix, but find that even though the matrix A is a
Tanzania [10]

Answer:

  The system will be found to be inconsistent or dependent.

Step-by-step explanation:

The matrix A will have no inverse for two different reasons:

  1. The system is inconsistent
  2. The system is dependent

In the latter case, the Gauss-Jordan method will find a set of parametric equations for a solution. In the former case, there is no solution.

The outcome will depend on the reason why there is no inverse.

The fith term of a G.P is 8 times the 2nd term find its common ratio​
Dovator [93]

Answer:

Common ratio r = 2

Step-by-step explanation:

\because the fith term of a G.P is 8 times the 2nd term.

\therefore  \: t_5 = 8\times t_2 \\ \therefore  \: ar^{5-1}=8\times \: ar^{2-1}  \\ \therefore  \: r^{4}=8\times \: r^{1} \\ \therefore  \: r^{3}=8 \\ \therefore  \:r^{3}= {2}^{3}  \\   \hspace{20 pt}\huge \red{ \boxed{\therefore  \:r= {2}}} \\

Hence, common ratio is 2.

105% of 60 and small explanation
natulia [17]
Whenever you see the word "of" in the mathematical terms. it always mean you have to multiply

105%(60) = ?

105 ÷ 100 = 1.05
= 105/100 = 1.05

We multiply "60" from "1.05"
1.05 (60) = 63

So, therefore your answer would have to be: 63
