Answer:
Step-by-step explanation:
Let x be the number of books she made in total
On first day she made 1/6 x books
On second day she made 48 books.
The number of books she made on second day is 1/5 more than she made on first day so - so she made 48 / 6/5 = 40 on first day
605 pounds is 840.25 dollars
405 dollars is 313.30 pounds
Answer:D.51
Step-by-step explanation:180-68-61=51
Choice C, it has the same slope as the given equation without being identical to it like choice a.
Answer:
The maximum volume of the open box is 24.26 cm³
Step-by-step explanation:
The volume of the box is given as
, where
and
.
Expand the function to obtain:

Differentiate wrt x to obtain:

To find the point where the maximum value occurs, we solve



Discard x=3.54 because it is not within the given domain.
Apply the second derivative test to confirm the maximum critical point.
, 
This means the maximum volume occurs at
.
Substitute
into
to get the maximum volume.

The maximum volume of the open box is 24.26 cm³
