Answer:
Length of first piece = 1.7058823 ft
Length of second piece = 4(1.7058823) = 6.82352941 ft
Length of third piece = 12(1.7058823) = 20.47058823 ft
Step-by-step explanation:
As given, Total length of the board = 29 ft
Let the board is divided into 3 pieces
Suppose that the length of first piece = x ft
As given, the second piece is 4 times longer than the first
⇒Length of second piece = 4x ft
Also given, the third piece is 3 times longer than the second.
⇒Length of third piece = 3(4x) = 12x ft
Now,
As total length of board = 29
⇒ x + 4x + 12x = 29
⇒ 17x = 29
⇒ x = = 1.7058823 ft
∴ we get
Length of first piece = 1.7058823 ft
Length of second piece = 4(1.7058823) = 6.82352941 ft
Length of third piece = 12(1.7058823) = 20.47058823 ft
Answer:
After 5.31 months sales will drop below 1000 and 5 months after the end of the campaign sales will be 1282.09
Step-by-step explanation:
Let's find the solutions for the two questions.
First question: How many months after the end of the campaign will sales drop below 1000.
Because the problem asks for how many months, and since 'x' represents month variable, then the problem is asking for 'x'.
Using the same equation for sales we can observe the following:
, but we have S which is 1000, so:
which is equal to:
which is equal to:
by applying ln(x) properties:
which is equal to:
which is equal to:
so:
Second question: what will be the sales 5 months after the end of the campaign.
Because the problem asks for what will be the sales, and since 'S' represents the sales, then the problem is asking for 'S'.
Using the same equation for sales we can observe the following:
, but we have x which is 5 months, so:
which is equal to
In conclusion, after 5.31 months sales will drop below 1000 and 5 months after the end of the campaign sales will be 1282.09.
