Answer:
Option A. 64x^3
Step-by-step explanation:
From the question, we were able to obtain the following:
L = 4x
In cubic units,
Volume = L^3
Volume = (4x)^3
Volume = 64x^3
I believe the answer is 87.5
2a^3 when a = 4:
First, to start out, our step should always be to substitute the value of the variable (a) into the problem. Below is what our new problem should look like with the value of the variable. Keep in mind that parentheses mean multiplication.
Second, our next step is to simplify 4^3. Four raised to the third power equals 64, so 4^3 = 64.
Third, this last step is quite easy. All you need to do is (2 times 64). Best to use a calculator on this or take the hard way and do long multiplication. Either way, the answer for 2 times 64 is 128.
Answer:
Which relation is a function? A. {(8,3), (-1,-1), (8,7), (-1,7)} B. {(1,6), (2,-3), (2,7), (3,7)} C. {(-3,6), (-3,9), (-1,4), (0

A. Not a function since x = 8 repeats. We have x = 8 pair up with y = 3 and y = 7 at the same time.
B. Not a function for similar reasons. Now x = 2 repeats. We have x = 2 pair up with y = -3 and y = 7
C. Not a function. We have x = -3 pair up with both y = 6 and y = 9 at the same time.
D. This is a function. Each x value is listed once and only once. Any input (x) leads to exactly one output (y). For choices A through C, it is possible to draw a vertical line through more than one point, thereby failing the vertical line test. In choice D, it is not possible to draw a vertical line through more than one point of this list. So this relation passes the vertical line test.
Answer: Choice D
