Answer:
a
Step-by-step explanation:
We need to find the maximum (Vertex of the function)
Let:
L = Length = 1500 - 2x
W = Width = x
The area is given by:
We can find the maximum using the following formula:
Evaluate the area for the value we found previously:
The largest area that can be enclosed is 281250m²
Well, we should first decide on our variables. Let's replace "thumb drives" with the letter "t", and "compact disk" with the letter "c".
Now, to understand the sentence. "5 thumb drives have 9 gigabytes more capacity than 1 compact disk." So, what does that mean? Well, if a compact disk has 10 gigabytes of capacity, then I suppose 5 thumb drives would have 19 gigabytes of capacity all together. So, we're just adding +9.
Alright, so as a linear equation:
"5 thumb drives have 9 gigabytes more capacity than 1 compact disk"
5t = c + 9
Y=k/x²; substitute x=1 and y=1/8: 1/8=k. So y=1/(8x²)
When x=5, y=1/(8×25)=1/200.
3.11111... = 3 + 1/9 = 28/9
Every time you see such a repeating decimal, it's basically a fraction with 9's in the denominator.
For example:
0.222... = 2/9
0.45454545... = 45/99
0.274274274... = 274/999
