Answer:
its C
Step-by-step explanation:
Volume
of a rectangular box = length x width x height<span>
From the problem statement,
length = 60 - 2x
width = 10 - 2x
height = x</span>
<span>
where x is the height of the box or the side of the equal squares from each
corner and turning up the sides
V = (60-2x) (10-2x) (x)
V = (60 - 2x) (10x - 2x^2)
V = 600x - 120x^2 -20x^2 + 4x^3
V = 4x^3 - 100x^2 + 600x
To maximize the volume, we differentiate the expression of the volume and
equate it to zero.
V = </span>4x^3 - 100x^2 + 600x<span>
dV/dx = 12x^2 - 200x + 600
12x^2 - 200x + 600 = 0</span>
<span>x^2 - 50/3x + 50 = 0
Solving for x,
x1 = 12.74 ; Volume = -315.56 (cannot be negative)
x2 = 3.92 ;
Volume = 1056.31So, the answer would be that the maximum volume would be 1056.31 cm^3.</span><span>

Answer:
8 7
Step-by-step explanation:
Because the number will be positive
Answer:
To know how much he bought it for, let's consider the actual amount it be x.
Step-by-step explanation:
10% of x + $585 = x
x/10 + $585 = x
$585 = x-x/10
$585= 9x/10
9x=$5850
x=$5850/9
x=$650
.: the actual price was $650.
Drone = $300
4 Extra Set Of Propellor = 4(25$) = $100
