Let f and s represent the weights of the first and second objects, respectively.
.. f - s = 200 . . . . . . . . the first is 200 lb heavier than the second
.. s = (1/3)f . . . . . . . . . . the second was 1/3 the weight of the first

In augmented matrix form, the equations can be written
.. f - s = 200
.. f - 3s = 0

The solution is
.. f = 300
.. s = 100
Their total weight is 400 lb, not enough to kill Mr. Boddy. The physics-loving professor is apparently innocent.

The graph shows the data points in the table and the exponential regression model associated with the data ?
Ipatiy [6.2K]
From the graph, it is obvious that the trend is decreasing from 100 on day 2, to 1 on day 10. So, the answer could either be A or C. The question would be how fast is it decreasing? To illustrate this, let's find the difference of consecutive data:

100 - 26 = 74
26 - 6 = 20
6 - 2=4
2-1=1

It must not be an additive rate because there is no common difference. Let's illustrate if the trend is in multiplicative rate:

100/26 = 3.85
26/6 = 4.33
6/2 = 3
2/1 = 2

More or less, they have a common divider. Hence, the decreasing rate is in multiplicative rate. The answer is A.
