It would be a vertical stretch by a factor of 3. Letter B
For example: when x= 10 in f(x) y = 3 and in g(x) y = 9
We know that the side lengths of the square base are: x * x. The volume is 12, so for now, let's say that y is the other side length. Then, x * x * y = 12. We can solve for y: y = 12/x^2. Now, we find the surface area of the 5 sides.
Four of the sides have the same area: x * (12/x^2) = 12/x, so we multiply this by 4: 48/x.
The last side is the base: x * x = x^2.
We add 48/x to x^2:
x^2 + 48/x
So, the answer is the fourth choice, (d).
28/4 = 7
there is no decimal expansion
Answer:
1.20 or 120 cents
Step-by-step explanation:
First, we need to calculate the total due for the book. 15 cents(3 days) = 0.45
Next, we need to calculate the total due for the video. 25 cents(3days) =0.75
0.75+0.45=1.2 dollars, or 120 cents
