G(x) x^2-11 is a translation of f(x) x^2 shifted 11 units down
Answer:
Let y represents the maximum variation in the level of chlorine,
Given,
Level of chlorine in a hot tub is within 1.75 ppm of 3.25 ppm.
So, the standard level of chlorine = 1.75 + y or 3.25 - y
⇒ 1.75 + y = 3.25 - y
⇒ 2y = 5
⇒ y = 2.5
Thus, the standard level would be 2.5 ppm,
If x represents the present level of chlorine,
Then it would be lie within 1.75 ppm of 3.25 ppm.
If the difference between x and standard level ≤ Maximum variation
⇒ |x-2.5| ≤ 0.75
Which is the required absolute value inequality to represent this situation.
b. If x = 1.0 ppm,
Since |1.0-2.5|=1.5 which is not less than equal to 0.75,
Hence, he should add more chlorine.

Answer:
807.8 in^2
Step-by-step explanation:
The total area of the box is the sum of the areas of all faces of the box. The top, bottom, front, and back faces are rectangles 18 in long. The end faces each consist of a rectangle and a triangle. We can compute the sum of these like this:
The areas of top, bottom, front, and back add up to be 18 inches wide by the length that is the perimeter of the end: 2·5in +2·8 in + 9.6 in = 35.8 in. That lateral area is ...
(18 in)(35.6 in) = 640.8 in^2
The area of the triangle on each end is equivalent to the area of a rectangle half as high, so we can compute the area of each end as ...
(9.6 in)(8.7 in) = 83.52 in^2
Then the total area is the lateral area plus the area of the two ends:
640.8 in^2 + 2·83.52 in^2 = 807.84 in^2 ≈ 807.8 in^2
