The answer is the book is approximately 15.3 inches tall, and it will fit on the shelf, since 16 inches is greater than 15.3 inches.
Here's an explanation:
The problem has already said that the book shelf is 16 inches tall. It's given that the area of the front cover of a square book is 234 square inches. Since the book is square, the length of the book will be equal to the width of the book. So, the find the length of the book, you would find the square root of 234, since both sides would be the same, and you'd get an answer of approximately 15.3 inches. If the length of the book is 15.3 inches, then it would fit on the book shelf, since 15.3 inches is less than 16 inches.

Domain Definition: The domain of a function is the set of input or argument values for which the function is real and defined
<u>squareroot 2x + 10</u> ⇒ <u>2x + 10 ≥ 0</u>
Solve 2x + 10 ≥ 0:
Subtract 10 from both sides
2x + 10 - 10 ≥ 0 - 10
Simplify
2x ≥ -10
Divide both sides by 2
2x / 2 ≥ -10 / 2
Simplify
2x / 2
Divide the numbers: <u>2 / 2 = 1</u>
= x
Note: x has the same value as 1
Divide the numbers: -10 / 2 = -5
= -5
The function domain is
x ≥ -5
For the first plan, we can write it as 57+0.11m if m represents the miles driven due to that we have a base value of 57 but add $0.11 per mile . Similarly, for the second plan we can write 50+0.13m. Since we want them to be equal, we have 57+0.11m=50+0.13m. Subtracting 0.11m as well as 50 from both sides, we get 0.02m=7. Next, we can multiply both sides by 50 to get 350=the amount of miles needed for them to be the same. For the cost, we can plug 350 into either expression to get 57+0.11*350=95.5 dollars
