The total number of unique subset of 5 letter words possible are 840 and the total number of different strings that could be made 5040.
The word 'unusual' contains a total of 7 letters.
A subset of 5 letters from the seven letters of the word unusual can be found out by making the combinations of all the five letter words possible from the seven letters.
As we can see that there are total of 7 letters among which u is repeated three times. Number of the possible combinations for the subset of 5 letter word are,
= 7×6×5×4
= 840.
So, there are 840 subset possible.
The total number of Strings that are possible is,
= 7×6×5×4×3×2×1
= 5040.
So, the total number of Strings possible are 5040.

Answer:

Step-by-step explanation:
Given :-
The sum of two numbers is 1 .
The product of the nos . is 12 .
And we need to find out the numbers. So let us take ,
First number be x
Second number be 1-x .
According to first condition :-

Hence the numbers are 4 and -3.
Given that we need to determine the radius of the circle.
<u>Radius:</u>
By definition of radius of circle, the radius is the length of the line which is drawn from the center of the circle to any point on the circle.
From the figure, we need to determine the radius of the circle.
As, we can see that, the distance from the center of the circle to the point on the circle is 11 cm.
Since, we know that, the radius is the distance from the center of the circle to the point on the circle then, the radius of the given circle is 11 cm
Thus, radius of the circle is 11 cm.
