Explain why Rolle's theorem does not apply to the function even though there exist a and b such that f(a) = f(b). (Select all that apply.) f(x) = cot x2 , [𝜋, 5𝜋] There are points on the interval (a, b) where f is not differentiable.There are points on the interval [a, b] where f is not continuous.f(a) does not equal f(b) for all possible values of a and b in the interval [𝜋, 5𝜋].f ′(a) does not equal f ′(b) for any values in the interval [𝜋, 5𝜋].None of these.

Content Problem A You have a 4.1 mol pure sample of an unknown material. After 4.8 h, you discover that 15% has decayed. Determine the half-life, decay constant, mean life, & initial decay rate. Also determine what the decay rate is at 4.8 h. $T_{1/2} =$ $\lambda =$ $\tau =$ $R_0 =$ $R =$ decays/h decays/h Problem B The decay rate of a radioactive source decreases by 58% in 29 h. Determine the half-life, decay constant, & mean life of the source. $T_{1/2} =$ $\lambda =$ $\tau =$ Submit Answer
