Answer:
The practical domain of the function is [30,32].
Step-by-step explanation:
The given function is
where, p(h) represents the Vonda's weekly pay as a function of hours worked.
She pays a one time $250 chair rental fee, and earns $40 per hour that she works.
Domain is the set of all possible inputs.
The possible domain of the given function is all real numbers but the number of hours can not be negative, therefore h>0.
It is given that Vonda works between 30 and 32 hours per week at a hair salon. So,
Therefore practical domain of the function is [30,32].
Answer: The true statements are:-
1.The square root of a positive number greater than 1 is less than the number.
as 2<4
2.The square root of a positive number less than 1 is between 0 and 1.
as square root of 0.04 is 0.2 which lie between 0 and 1.
Step-by-step explanation:
2.The square root of a positive number is always less than half of the number itself . It is not true always , for example the number is 4 then the square root of 4 =2 and it is not less than half of 4=2 .
3.The square root of a positive number less than 1 is less than the number.
It is not true ,as 0.04=
⇒ 0.2 is the square root of the number and is not less than the number.
4 .The square root of a perfect square is not a whole number. It is not true, as 4 is a perfect square and its square root is 2 which is a whole number.
