Answer:
Step-by-step explanation:
Given that rectangle has side length 23x13 feet.
When squares of side x are cut from all the four sides we have dimensions as
23-2x and 13-2x and height x
Volume 

Use derivative test
First derivative V'(x) 
Equate I derivative to 0
We get approximate value of x = 2.671, 9.329
Since width is 13 feet it cannot be 9.329
Hence x = 2.671
V"(x) = -80 <0
So maximum volume is

Answer:
$35.13
Step-by-step explanation:
monthly payment = (cost - down payment) / number of month
(975 - 132) / 24 =
843/24= 35.13
Answer:
<em>x = -11</em>
Step-by-step explanation:
<u>Equations</u>
The image shows a right triangle with angles 70°, 90°, and x+31.
The sum of the internal angles of a triangle is 180°, thus:
70 + 90 + x + 31 = 180
Simplifying:
191 + x = 180
Subtracting 191:
x = 180 - 191
x = -11
