Step-by-step explanation:
The correct domain is [3,8].
Answer:
Step-by-step explanation:
Alright, lets get started.
Area is given as 49 square inches.
The formula for area A = 
base is given as x
Height is given as x
Hence area is A
A = 
Multiplying 2 in both sides
Taking square root on both sides
hence the answer is x = 9.9 in : Answer
Hope it will help :)

Answer: 10^4</h3>
This is an exponential expression with 10 as the base and 4 as the exponent.
=============================================
Explanation:
We're dividing 10^8 over 10^4. When dividing like this, we subtract the exponents (numerator minus denominator). The bases must be the same value and they stay at the same value for the final answer as well.
The new exponent is 8-4 = 4 which is how we arrive at the answer 10^4.
Side note: 10^4 = 10,000 = ten thousand
