Answer:
C. This is true. If there is more than one entry equal to 0, all powers of P will contain 0 entries. Hence, there is no power k for which Upper P Superscript k contains all positive entries. That is, P will not satisfy the definition of a regular matrix if it has more than one 0
Step-by-step explanation:
The correct option is C as it represents that by considering a matrix P that involves more than one zero and at the same time the powers for all P has received minimum one zero or it included at least one zero
Therefore the statement C verified and hence it is to be considered to be valid
Hence, all the other statements are incorrect
Answer:
The quadratic equation is (x + 3)(x + 4) = 5
Step-by-step explanation:
If the degree of a polynomial is two then the polynomial is known as a quadratic.
Now, in the given equations we see which polynomial has a degree 2.
Simplify the first equation

Degree is 3 and hence it is not a quadratic.
Take 2nd equation

Degree is 1 and hence it is not a quadratic.
Finally, we simplify the third equation

Apply FOIL method to simplify the left hand side

Degree is 2 and hence it is a quadratic equation.
Hi there!
In order to answer your question, you'll need to use the cross product method:

<u>(100 × 270)</u> ÷ 1,800 = X
<u>27,000 ÷ 1,800</u> = X
15 = X
= 15%
Your answer is: Isaac put 15% of his earnings into his savings.
There you go! I really hope this helped, if there's anything just let me know! :)
