The domain for f(t) is all of the numbers t for which f(t) is defined.
In other words, its all of the numbers that t minutes can be and still make sense in the function.
f(t) is distance from sea level as a function of time. It does not make sense to have negative time, so t must be 0 or a positive number. t does not necessarily have to be an integer (a whole number), since you can have time values like half a minute.
Answer is <span>C. the set of all real numbers greater than or equal to zero</span>
<12 would be A (51 degrees) because 2 and 10 are corresponding angles and there are 180 degrees on a straight line!
Hope this helps :)
I believe 4 because it has to do a 360 degrees turn to be facing in the same position , 4 x 90 = 360
Answer and explanation:
Given : Expression 
as ![\sqrt[4]{16}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B16%7D)
To find : Use properties of exponents to explain why it makes sense to define expression ?
Solution :
Using property of exponent,
![x^{\frac{1}{n}}=\sqrt[n]{x}](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7B1%7D%7Bn%7D%7D%3D%5Csqrt%5Bn%5D%7Bx%7D)
On comparing with given expression,
Here x=16 and n=4
![(16)^{\frac{1}{4}}=\sqrt[4]{16}](https://tex.z-dn.net/?f=%2816%29%5E%7B%5Cfrac%7B1%7D%7B4%7D%7D%3D%5Csqrt%5B4%5D%7B16%7D)
Hence by property it defied the expression.
