Answer:
59.52 days
Step-by-step explanation:
So this is a simple problem we can solve easily
If it takes 3 days to read 50 pages then obviously his rate of reading is 50 pages per day
If we divide 992 by 50, then we can find how many 3 day increments it will take him
(992/50 is 19.84)
Now is we multiply 19.84 by 3, we get the total amount of days which is 59.52
I hope I helped and have a wonderful day!
Let
be the dimensions of the rectangle. We know the equations for both area and perimeter:


So, we have the following system:

From the second equation, we can deduce

Plug this in the first equation to get

Refactor as

And solve with the usual quadratic formula to get

Both solutions are feasible, because they're both positive.
If we chose the positive solution, we have

If we choose the negative solution, we have

So, we're just swapping the role of
and
. The two dimensions of the rectangle are
and 
The answer is
g'(x)=<span>4x^3-10x=0 so </span><span>(4x-10)x=0 it is x= 0 and x= 5/2
</span>
<span>g(0)=4
</span>
<span>g(5/2)=x^4-5x^2+4=11.81</span>
the minimum is M(0, 4)
