Answer:

$0.002403$ $= 2.403 * 10^{-3}$

Step-by-step explanation:

Given

$0.002403$

Required

Express as scientific notation

The rule of scientific notation is that:

It is represented in form of: $a * 10^n$ where $1 \le a \le 10$

$0.002403$ will be represented as: a = 2.403; notice that the point was shifted forward by 3 units.

So:

n = -3

The equation becomes:

$a * 10^n$

$0.002403$ $= 2.403 * 10^{-3}$

Approximate

$0.002403$ $= 2.4 * 10^{-3}$

Suggestion:

The width is the x value and the hight is the y value.

Plot the points on the graph as decimal if that helps.

The point at the bottom left is the origin (0,0)

I hope this helps.
