Answer:
864 ft3
Step-by-step explanation:
length = 12 ft
width = 8 ft
depth = 9 ft
Volume = ? = length * width * depth
Answer:
x=68/3 (or 22.66666...)
Step-by-step explanation:
refer to drawing
Here it is:
The first set has (0,1) and (0,5), which assigns to the *same* x, more than one value of *y*. That's not a function. It's a curve. Think about a circle, or instance. It's NOT a function, but it's a curve.
The second one has for each *x* a single *y*
BTW, there's no problem if for *different* x there is the same *y*:
y = 5,
all x, have the same y, equal to 5. That's a function, or y = x^2, etc
under a rotation about the origin of 180°
a point (x, y ) → (- x, - y )
hence D is correct, both the x and y coordinates of the points on ΔA'B'C' have opposite signs from the corresponding points on ΔABC
