Answer:
it’s in order but switch the 3/8 and the 1/4?
Step-by-step explanation:
Let the side length of each of the squares cut out be x inches.
The volume of the box will be:-
V = x(19 - 2x)(11 - 2x)
V = x( 209 - 38x - 22x + 4x^2)
V = x(209 - 60x + 4x^2)
V = 209x - 60x^2 + 4x^3
For maximum/minimum volume we find the derivative and equate to zero:-
dV/dx = 209 - 120x + 12x^2 = 0
solving for x:-
x = 7.75 , 2.25
For maximum volume evaluate the second derivative:-
d^2V/dx^2 = 24x - 120
for x = 2.25 second derivative = 24(2.25) - 120 = -66 so x = 2.25 gives a maximum volume.
Answe:- r the dimensions of the squares is 2.25 * 2.2.5 inches
33 degrees,
90-57=33
complementary angles mean that together, the angles add up to equal 90 degrees
X= 48 is the correct answer. You can always plug in 48 back into the original equation and make sure it works.
48-23+84+48+23=180
