That person should be right
Hope this helps good luck
Answer:
No.
Step-by-step explanation:
An irrational number has never-ending decimals.
A rational number can be written as a fraction or has a terminating decimal.
-7.8 can be rewritten into a fraction. Its decimal also terminates. Therefore, it is not irrational but rational.
The correct answer is option A which is the value a₃₂ = 7.
<h3>What is the matrix?</h3>
A matrix is a specific arrangement of items, particularly numbers. A matrix is a row-and-column mathematical structure. The a_{ij} element in a matrix, such as M, refers to the i-th row and j-th column element.
In the given matrix the value of a₃₂ means that the element of the third row and the second column.
So the value of a₃₂ will be 7. which is present in the third row and the second column.
Therefore the correct answer is option A which is the value a₃₂ = 7.

The largest ellipse that will fit in that table will be:
(x/(37.5/2))^2+(y/(25/2))^2=1
(x/18.75)^2+(y/12.5)^2=1
The foci will be at:
±c^2=a^2-b^2
±c^2=(18.75)^2-(12.5)^2
±c^2=195.3125
±c≈13.975
So the foci will be at approximately (-14,0) and (14,0)
