Length = 3cm
1/2 cm cube = 3 ÷ 1/2 = 3 x 2 = 6
Width = 4cm
1/2 cm cube = 4 ÷ 1/2 = 4 x 2 = 8
Height = 5cm
1/2 cm cube = 5 ÷ 1/2 = 5 x 2 = 10
Number o 1/2 cubes = 6 x 8 x 10 = 480
Answer: 
Step-by-step explanation:
When any number has a negative exponent, all the negative exponent is doing is flipping the sides.
When we plug -3 in for x we get 
.
Now just imagine the -3 in fraction form as 
. And all you do now is just flip the sides to get 
And now apply the exponent 2 to the 1 and negative 3.
1 to the power of 2 is just 1
-3 to the power of 2 is 9.
So your answer is

Answer:
Step-by-step explanation:
(a) Your $160 is correct.
(b) No, this is not a proportional relationship, because the graph does not go through the origin. That, in turn, is because there is a fixed, up-front cost of $120.
(c) The total cost as a function of the number of months, m, is
TC(m) = $120 + ($40/month)m
