SOLUTION
Given the question on the question tab;
The trace on the graph is given below;
Final answer:
The volume of the box when x=1 is 15 cubic inches.
Answer:
You probably should have gave them 2/3 of what they did. I wouldn't call you a scammer, but it was not fair.
The answer is C.
It has a negative slope (-40) and a y-intercept at 200.
After 1 hour, 360 g decays to 180 g.
After another hour (total 2 hours), 180 g decays to 90 g.
After another hour (total 3), 90 g decays to 45 g.
After one more (total 4), 45 g decays to 22.5 g.
More quickly, with a half-life of 1 hour, the 360 g of starting material decays to
(360 g) / 2⁴ = 22.5 g
In general, if the half-life is 1 hour, then after <em>n</em> hours, an initial amount <em>A</em> of this substance decays according to
<em>A</em> / 2<em>ⁿ</em>
