The inequality can be used to find the domain of
Answer: Option B
<u>Step-by-step explanation:</u>
We have , domain is the set of all possible x-values which will make the function "work", and will output real y-values. Basically to find domain of any function means to find range of values of x that will give real values of y.
For the equation , we know that there's no value ( iota or complex numbers are there but here we will deal with real numbers ) of negative numbers under square root
∴ must be greater than or equal to 0.

Answer
Find out the what was his total cost .
To prove
As given
A tent was marked up 150% from an original cost of $52.
Last Friday, Ethan bought the tent and paid an additional 10% in sales tax.
Than the equation becomes
150 % is written in the decimal form .
= 1.5
10 % is written in the decimal form .
= 0.1
cost of the tent when 150% marked up from origianl price = 1.5× 52
= $ 78
cost of the tent = origianl cost + 150% marked up from origianl price
= $52 + $78
= $ 130
Sales price on the tent = $130 × 0.1
= 13
Total cost of the tent = $130 + $13
= $143
Therefore the cost of the tent is $143.
