Answer:
Step-by-step explanation:
y=4 times 1/2 to the power of x can be written symbolically as
4 4
y = 4(1/2)^x. This is the same as y = ------- or y = -------- * 2^(-x)
2^x 1
This function is a "decaying exponential."
A suitable table follows:
x 4(2^[-x]) x y
0 4(2^0) (0, 4)
1 4(2^1) (1, 8)
2 4(2^2) (2, 16)
and so on.
B) ABCD is a rhombus as all the sides are congruent (equal)
so you can either do pounds per dollar or dollars per pound:
pounds per dollar : about 0.71 lbs / $
dollars per pound : $1.40 / lb
i hope this helped, based on the question i believe that it is dollars per pound but its good to know both and have a nice day
