Ответ:
25π = πr²
25 = r²
We need only positive root.
√25 = √r
r= 5 inch
Ответ:
(-infinity, -2) ∪ (-2, infinity)
Step-by-step explanation:
I will have to assume that you meant
f(x)=(x-3)/(x+2). You must use parentheses to specify the order of operations in this problem.
x can take on any value except -2, at which the function is undefined.
Thus, the domain is (-infinity, -2) ∪ (-2, infinity)
