<u>Convert mm to cm:</u>
130mm = 13cm
<u>Formula:</u>
Volume = Length x Width x Height
<u>Substitute known values into the variables:</u>
1404 = 9 x 13 x height
1404 = 117 x height
height = 1404 ÷ 117 = 12 cm
Answer : Height = 12 cm
Using a geometric sequence, the number of emails sent on day 7 is given as follows:
A. 93,312.
<h3>What is a geometric sequence?</h3>
A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.
The nth term of a geometric sequence is given by:

In which
is the first term.
This situation can be modeled by a geometric sequence with first term and common ratio given as follows:

Hence the number of people that receive the email on day n is:

On day 7, the amount is:

Hence option A is correct.
