Rounded to three decimal places, the value of the irrational number e is

Hello mate!

The number e is: e = 2.71828

Now, we want to round it to 3 decimal places.

First, let's talk about the round part.

If we have a number of the form x = a.b and we want to round it tho the whole number, we need to analyze the number after the decimal point.

if the number b is smaller than 5, then we round down and x = a

if the number b is 5 or bigger, then we round up and x = a + 1

now, the number in the 3 decimal place is an 8, and we need to see the next number (the fourth place) in this case is a 2, so this means that we need to round down.

e = 2.718

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
