Possible derivation:
d/da(4 - 8 a)
Differentiate the sum term by term and factor out constants:
= d/da(4) - 8 (d/da(a))
The derivative of 4 is zero:
= -8 (d/da(a)) + 0
Simplify the expression:
= -8 (d/da(a))
The derivative of a is 1:
= -8 1
Simplify the expression:
Answer: = -8

Answer: 56 boxes
Step-by-step explanation: each box is worth 7.5 cubic feet, and if the space is 65% full, the remainder of space, being 420 cubic feet, can hold 56 boxes
Answer:gdjdh
Step-by-step explanation:
Fill in each slot in the square with variables <em>a</em>, <em>b</em>, <em>c</em>, <em>d</em>, and <em>e</em>, in order from left-to-right, top-to-bottom. In a magic square, the sums across rows, columns, and diagonals all add up to the same number called the <em>magic sum</em>.
The magic sum is -3.9, since "diagonal 2" (bottom left to top right) has all the information we need:
3 + (-1.3) + (-5.6) = -3.9
Use this to find the remaining elements
<em>a</em> + <em>b</em> + (-5.6) = -3.9
<em>c</em> + (-1.3) + <em>d</em> = -3.9
3 + <em>e</em> + 0.02 = -3.9
<em>a</em> + <em>c</em> + 3 = -3.9
<em>b</em> + (-1.3) + <em>e</em> = -3.9
(-5.6) + <em>d</em> + 0.02 = -3.9
- diagonal 1 (top left to bottom right):
<em>a</em> + (-1.3) + 0.02 = -3.9
You will find
<em>a</em> = -2.62
<em>b</em> = 4.32
<em>c</em> = -4.28
<em>d</em> = 1.68
<em>e</em> = -6.92
