Answer:
half an hour is 30 minutes
a quarter of an hour is 15 minutes
30/15 = 2
2 quarter hours = 1 half hour
Answer:
See below.
Step-by-step explanation:
This inequality is < 0 for all real values of x. We see this by solving -x^2 - 6 = 0 for x:
-x^2 - 6 = 0
-x^2 = 6
x^2 = -6 for which there are no real solutions of x. So the graph does not pass through the x axis.
At x = 0. f(x) < -6 so that is the one critical value - all values of f(x) are below this value.

Answer with Step-by-step explanation:
We are given that a function
on the interval [-1,1]
Rolle's theorem : It states that function is continuous on close interval [a,b] and differentiable on open interval (a,b) such that f(a)=f(b) , then
for some x ![a\leq x\leq b](https://tex.z-dn.net/?f=a%5Cleq%20x%5Cleq%20b)
![a=-1 , b=1](https://tex.z-dn.net/?f=a%3D-1%20%2C%20b%3D1)
![f(1)=1](https://tex.z-dn.net/?f=f%281%29%3D1)
![f(-1)=(-1)^{\frac{1}{3})=-1](https://tex.z-dn.net/?f=f%28-1%29%3D%28-1%29%5E%7B%5Cfrac%7B1%7D%7B3%7D%29%3D-1)
![f(-1)\neq f(1)](https://tex.z-dn.net/?f=f%28-1%29%5Cneq%20f%281%29)
![f'(x)=\frac{1}{3x^{\frac{2}{3}}}](https://tex.z-dn.net/?f=f%27%28x%29%3D%5Cfrac%7B1%7D%7B3x%5E%7B%5Cfrac%7B2%7D%7B3%7D%7D%7D)
f is not differentiable at x=0.Therefore , f(x) is not diffrentiable on interval (-1,1)
Hence, Rolle's threorem cannot be applied for given function because it does not satisfied the condition of rolle's theorem.
