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

This may help you

he functión Cot[x/2] is not continuos in the points <span>x=2nπ, where n=0,1,2,3,...</span> You can check it with a calculator. So the function is not continuos in the domain the problem gives you, so the Rolle's theorem can not be applied. If the inteverval was, <span>[π/2,3π/2]</span> Then we could apply the Rolle's theorem.

Answer:

1. $445\frac{1}{2}$

2. $-1\frac{1}{12}$

3. $2\frac{11}{30}$

Step-by-step explanation:

1. $9\frac{9}{10} +2\frac{1}{4}$

I like to make it an improper fraction first.

$\frac{99}{10}+\frac{9}{4}$

Now take the LCM. The LCM is 20.

$\frac{198}{20} +\frac{45}{20}$

Now add them.

$\frac{8910}{20}$

Make this into a mixed number.

$445\frac{1}{2}$

That's your answer for number 1.

2. $6\frac{1}{4} -7\frac{1}{3}$

Do the same thing as the previous addition problem but subtract instead.

$\frac{25}{4} -\frac{22}{3}$

$\frac{75}{12} -\frac{88}{12}$

$-\frac{13}{12}=-1\frac{1}{12}$

$-1\frac{1}{12}$ is your answer for number 2.

3. $8\frac{2}{3}-6\frac{3}{10}$

$\frac{26}{3} -\frac{63}{10}$

$\frac{260}{30}-\frac{189}{30}$

$\frac{71}{30}=2\frac{11}{30}$

$2\frac{11}{30}$ is your answer for number 3.

I hope this helps! Let me know if you need help or if I got anything wrong :)
