Step-by-step explanation:
we have 8 equally "heavy" batches.
one weighs 3.9 × 10^-10 g
so, the total sample then weighed
8 × 3.9 × 10^-10 = 31.2 × 10^-10 = 3.12 × 10^-9 g
<span>35.99 = 33 and 99/100</span>
Step-by-step explanation:

Step-by-step explanation:
In algebra, "y=" and "f(x)=" is basically the same thing. You don't have to write them both. Also, is in slope-intercept form, which is: , where is the y-intercept. That means "-5" is the y-intercept.
