Answer:

All real numbers

Step-by-step explanation:

We are given that a cube root function

$f(x)=\sqrt[3]{x}$

We have to find the domain of given function.

The given function defined for all real values of x.

$f(0)=0$

$f(-1)=(-1)^{\frac{1}{3}}=-1$

$f(-2)=(-2)^{\frac{1}{3}}=-1.259$

Therefore, domain of given function is the set of all real numbers.

Answer: All real numbers.

If an egg is thrown up and off the roof of a 100 foot building with an initial upward velocity of 10 feet per second, how long u

Deffense [45]

The equation of the height as a function of time for this case is given by:
h (t) = - 16t ^ 2 + 10t + 100
By the time the egg hits the ground we have:
-16t ^ 2 + 10t + 100 = 0
We look for the roots of the polynomial:
t1 = -2.2069555463432966
t2 = 2.8319555463432966
As it is about time, we use the positive root:
t = 2.83 s
Answer:
it hits the ground at:
t = 2.83 s
