If you notice the picture below, the amount of fencing, or perimeter, that will be used will be 3w + 2l
now
solve for "w", to see what critical points you get, and then run a first-derivative test on them, for the minimum
notice the
so. you can pretty much skip that one, though is a valid critical point, the width can't clearly be 0
so.. check the critical points on the other
Answer:
16
Step-by-step explanation:
The dimensions of the base of the prism are 4" by 2"; the height is 2".
Looking at the base, we see that (4)(2), or (8) 1" cubes would cover it exactly and wholly. We'd have a 3-dimensional prism with one layer of 1" cubes.
Now if we add a second layer right on top of the first layer, we'd have used (16) 1" cubes.
Answer:
depending on which triangle
For this case we have the following data:
700 rabbits that represent 500% of the population of last year. So, to obtain the rabbit population of last year, we developed a rule of three:
700 -----------> 500%
x ---------------> 100%
Where x represents the rabbit population of last year.
Clearing x we have:
rabbits
In this way, last year there was a population of 140 rabbits.
Answer:
140 rabbits
