What is the domain of f(x)=^3 sqrt x?
1 answer:
ANSWER
Domain is all real numbers.
EXPLANATION
We want to find the domain of the function,
![f(x) = \sqrt[3]{x}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Csqrt%5B3%5D%7Bx%7D%20)
The domain of this function refers to all values of x that will make the function defined.
When we plug in all real values into the above function, there will be a corresponding functional value.
Therefore the domain is all real numbers.

Answer:
<h2>x = 8.5in, y = 17in, r = 28°, s = 62°</h2>Step-by-step explanation:
If ΔJNZ and ΔKOA are similar, then corresponding sides are in proportion and corresponding angles are congruent.
We have the proportion:
and equations:
We have:
For y we must use the Pythagorean theorem:
<em>cross multiply</em>
<em>divide both sides by 8</em>
