-10, -10-2·1= -12, -10-2·2=-14, -10-2·3=-16, -10-2·4= -18, -10-2·5= -20,
-10-2·6= -22, -10-2·7 =-24, -10-2·8=-26, -10-2·9=-28
a=-10
d=-2
xn=a+d(n-1)
the first ten terms are
-10, -12, -14, -16, -18, -20, -22, -24, -26, -28
B) Models the equation, because:
Because y = money earned and x = amount of books she sells
When she sells a copy of each book this can be modeled by "2x"
When ever she sell's books, she get's a $5 tip (not affected by x),

Answer:
V = 64 and V = 2,048
Step-by-step explanation:
The volume of a cube is found using V = s*s*s. Substitute s = 4.
The volume is V = 4*4*4 = 64.
The volume of the crate is 32 * 64 = 2,048.
Answer:
base side = 20cm
height = 40 cm
minimum cost = $7200
Step-by-step explanation:
Let x (cm) be the base side and h (cm) be the height of the box. Since the volume of the box must be 16000 cubic cm, we have:
The areas of the top and bottom is
And so their cost is:
The areas of the sides is
And so their cost is:
We can substitute into the equation above to get
So the total cost of the bases and the sides:
This is the function we would want to minimize. We can start by taking the 1st derivative, and set it to 0
So the height would be
So the minimum total cost would be
