Answer: y = ½x - 2
Step-by-step explanation:
<u>Slope-intercept form: y = mx + b</u>
- m = slope =
- b = y-intercept ⇒ Substitute in a given point to the function to find b
y = ½x + b
2 = ½(8) + b
2 = 8/2 + b
2 = 4 + b
2 - 4 = b
b = -2
<u>y = ½x - 2</u>
Enter the cycle number, n, in the x column and the
number of radioactive atoms in the y column.

The more precise your length and width are, the more precise your area <span>measurement will be. Take this as example:
</span>width = 9.3045 mm
<span>length = 8.023 mm
</span><span>
Let's first round up:
width = 9.3 mm
length = 8 mm
Area = 9.3*8 = 74.4 mm
But if you are more precise with the width and length:
</span>width = 9.3045 mm
<span>length = 8.023 mm
</span>Area = 9.3045 * 8.023 = <span>74.6500035 mm
The more precise your length and width are, the more precise your area is. Also, as you can see t</span>he more precise your length and width are, the more your area will increase and will be more accurate.<span>
