2 answers:
Answer: Second Option is correct.
Step-by-step explanation:
Since we have given that
Number of readers = 3
Each of them forwarded the same email to number of readers = 3
So, our equation becomes
Similarly, each of them again forwarded the same email to number of readers = 3
So, our equation becomes
Again each of them forwarded the same email to number of readers = 3.
So, our equation becomes
So, Number of people have read that email is given by
Hence, Second Option is correct.

Answer:
Step-by-step explanation:
To calculate the lenght of the diagonal d across the square, we can assume that the square it is compound of two right triangles. So, we can resolve this exercise using The Pythagorean Theorem.
<em>The Pythagorean theorem</em> states that in every right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the respective lengths of the legs. It is the best-known proposition among those that have their own name in mathematics.
If in a right triangle there are legs of length a and b, and the measure of the hypotenuse is c, then the following relation is fulfilled:
a is the height, b is the base, and c is
the hypotenuse.
To obtain the value of the hypotenuse
To find the value of the lenght of the diagonal d across the square, we have:
Where a = b = 20
Substituting the values
Round the answer to 2 decimal places
