Answer:
Volume = 18 cubic feet
Surface Area = 44 square feet
Double width = Double the space
Step-by-step explanation:
Please see attached explanations.
Surface area is the area (one side multiplied by another) of every side of the storage box, added together.
I have labeled each unique pair of sides as a, b, and c. That is top and bottom, left and right side, and front and back side.
Volume is the length multiplied by the width multiplied by the height.
By doubling the width, you are doubling the size of the box in that given direction. You can prove this mathematically by making the width twice of what it was and finding volume again.

Answer:
C
Step-by-step explanation:
We want to integrate:
Notice that the expression in the denominator is quite similar to the expression in the numerator. So, we can try performing u-substitution. Let u be the function in the denominator. So:
By differentiating both sides with respect to x:
We can "multiply" both sides by dx:
And divide both sides by 5:
Rewriting our original integral yields:
Substitute:
Simplify:
This is a common integral:
Back-substitute. Of course, we need the constant of integration:
Our answer is C.
Answer:
For a triangle with <em>a</em> = 33, <em>c</em> = 48 and the angle , the missing side is <em>b = </em>60.4, and the missing angles are
and
.
Step-by-step explanation:
The Law of Sines says that in any given triangle, the ratio of any side length to the sine of its opposite angle is the same for all three sides of the triangle. This is true for any triangle, not just right triangles.
We know two sides <em>a</em> = 33, <em>c</em> = 48 and the angle , so we use the law of sines to find the angle
as follows:
One of the basic properties of triangles is that the sum of the measure of angles, in every triangle, is 180°.
So,
To find the side <em>b</em> we use the law of sines:
