Step-by-step explanation:



The new matrix obtained from a given matrix by interchanging it's rows and columns is called the transposition of matrix. It is denoted by
. Again , Interchange it's rows and columns in order to find ' A '.

Now , LEFT HAND SIDE ( L.H.S )

Here, I refers to identity matrix. A diagonal matrix in which all the elements of leading diagonal are 1 ( unit ) is called unit or identity matrix.

Step-by-step explanation:
Step-by-step explanation:
ABC be the given isosceles right triangle such that <B = 90° , side AC is the hypotenuse; and, AB= BC
Then, (AB)^2 + (BC)^2 = (AC)^2…. Pythagoras theorem.
(AC)^2 = 98 sq. cm. ( given)
So, (AB)^2 + ((BC)^2 = 98
But, AB = BC = a ( say) …. ( given)
Therefore, a^2 + a^2 = 98
Or, 2a^2 = 98.
So, a^2 = 98 / 2 = 49
Hence, a = AB = BC = √49 = 7 cm.
The side AC ( the hypotenuse) = √98 = √(7 *7*2)
= 7 *√2 = 7* 1.414 = 9..898cm., say, 9.9 cm.
Hence, the three sides of the right isosceles triangle are 7 cm, 7cm and ~ 9.9 cm. Answer

Answer:
13.5 lb/in^2
Step-by-step explanation:
8ft = 3.6 lb
30ft= ?
8ft÷30ft = 3.75
this means 8ft goes into 30ft 3.75 times
3.6lb× 3.75=13.5lb/in^2
you times the pressure of 8ft by 3.75 to find how much pressure there is at 30ft
