C=2•pi•r because C= pi•d and d=2•r
Q must be positive in F.
F. r squared will be positive, because any number times itself is positive, and to get a positive number for the answer, the two numbers you multiply need to be the same sign. If r squared is positive, q must be too.
G. q does not have to be positive. If r is a negative number, then q can be negative. Say q=-2 and r=-3. -2-(-3) changes to -2+3, which equals 1.
H. Again, q can be negative if r is negative (two negative numbers multiplied together equals a positive answer.
J. q can be negative because even a negative number turns positive when squared.
Hope this helped you. :)
75 divided by 60 times 6 equal 7.5
Answer:
distance
Step-by-step explanation:
lets say -7 what is -7 distance from 0
so the absolute value of -7 is 7
Answer:
For this case we have this function given:

In order to find the domain we need to find the possible values of x that the function can assume.
And we know that for this case the logarithm for 0 or neagtive numbers is not possible to calculate it, so then we can say that the domain for this case is:

And we can write this in formal notation as:
![D = [ X \in R | X>0]](https://tex.z-dn.net/?f=%20D%20%3D%20%5B%20X%20%5Cin%20R%20%7C%20X%3E0%5D)
And the best answer for this case would be:
all real numbers greater than 0
