Answer:
Step-by-step explanation:
First rule I'm going to use is the quotient rule:
Secondly, I'm going to rewrite the radical.
Third, I'm going to use the product rule on the first term:
Fourth, I'm going to use power rule for both of the last two terms:
30)
31)
a simple case for that would just be, using an equation with an imaginary value, let's do so
when you get a "solution" or zero with an "i" or an imaginary value, is just a way to say, there's really no solution, the function never touches the x-axis
R = 7 in. Therefore d=14
C=pi x d
= 3.14 x 14
= 43.96
