Answer:21
Step-by-step explanation:each cube has a volume of (1/3)^3 = 1/27 in^3
so, the total volume is 567/27 = 21 in^3
Answer:
13
Step-by-step explanation:
Answer:
, domain: all real numbers
Step-by-step explanation:
The two functions that we have in this problem are:

and

Here we have to calculate
(f+g)(x)
Which is equivalent to:

Taking the two functions and substituting into this expression, we find:

We also have to find the domain of the new function. However, we notice that there are no restrictions on the value of x, since this is a second-order function with no denominators, logarithms or roots: therefore, the domain is all real numbers.
