Explain why Rolle's Theorem does not apply to the function even though there exist a and b such that f(a)
Anna35 [415]

Rolle's Theorem does not apply to the function because there are points on the interval (a,b) where f is not differentiable.

Given the function is f(x)=\sqrt{(2-x^{\frac{2}{3}})^{3}}  and the Rolle's Theorem does not apply to the function.

Rolle's theorem is used to determine if a function is continuous and also differentiable.

The condition for Rolle's theorem to be true as:

  • f(a)=f(b)
  • f(x) must be continuous in [a,b].
  • f(x) must be differentiable in (a,b).

To apply the Rolle’s Theorem we need to have function that is differentiable on the given open interval.

If we look closely at the given function we can see that the first derivative of the given function is:

\begin{aligned}f(x)&=\sqrt{(2-x^{\frac{2}{3}})^3}\\ f(x)&=(2-x^{\frac{2}{3}})^{\frac{3}{2}}\\ f'(x)&=\frac{3}{2}(2-x^{\frac{2}{3}})^{\frac{1}{2}}\cdot \frac{2}{3}\cdot (-x)^{\frac{1}{3}}\\ f'(x)&=\frac{-\sqrt{2-x^{\frac{2}{3}}}}{\sqrt[3]{x}}\end

From this point of view we can see that the given function is not defined for x=0.

Hence, all the assumptions are not satisfied we can reach a conclusion that we cannot apply the Rolle's Theorem.

Jamie has 7/10 of a pound of chicken to cook for dinner if she's going to put the chicken in between three people how much chick
AURORKA [14]

Answer:

Each person will get \frac{7}{30} or approximately 0.23 pounds of chicken.

Step-by-step explanation:

This is a word problem involving fractions.  Using key words and phrases from the problem, we can decide which operation we need to use to solve.  Since Jamie is splitting the chicken equally between three people, she would need to divide the amount of chicken she has by 3:

\frac{7}{10}÷\frac{3}{1}

Since we can't divide fractions, we need to use the 'keep-change-flip' rule to keep the first fraction, change the operation to multiplication and flip the second fraction:

\frac{7}{10}*\frac{1}{3}=\frac{7}{30}

We can convert the fraction into a decimal by dividing the numerator by the denominator:  7÷30≈0.23 pounds per person.
