Answer:
The order of operations IS crucial because it will assist us in performing equations.
Step-by-step explanation:
(a)
<span>p'(25) = -1.179 millions of cells per cubic meter per meter.
The density of plankton cells in millions of cells per cubic meter is
decreasing at a rate of </span><span>1.179 millions of cells per cubic meter per meter.
____________
(b)
The volume is 3·dh, where dh is an infinitesimally small height.
Therefore, the amount of plankton is density * volume.
______
</span>
(c)
The total plankton cells are given by
As 0 ≤ f(h) ≤ u(h) for all h ≥ 0 (f and u are nonnegative), then:
Since ultimately
, that integral can have at most 105. Therefore, the maximum total amount is
____________
(d)
2/3x + 4=6. Is that what you mean?
Answer:
23/12 (1 11/12)
Step-by-step explanation:
2 3/4 = 11/4 and in order to do 11/4 minus 5/6, you would have to find the LCM (Least Common Multiple). The LCM is 12. 11/4 times 3 is 33/12 and 5/6 times 2 is 10/12. 33/12 minus 10/12 is 23/12. In a mixed fraction, this would be 1 11/12.
