Answer:
The equation represents the equation of the parabola with focus (-3, 3) and directrix y = 7.
Step-by-step explanation:
To find the equation of the parabola with focus (-3, 3) and directrix y = 7. We start by assuming a general point on the parabola (x, y).
Using the distance formula , we find that the distance between (x, y) is
and the distance between (x, y) and the directrix y = 7 is
.
On the parabola, these distances are equal so, we solve for y:
Answer:
12 cubes can fit in the create.
Step-by-step explanation:
We know that the volume of a the crate is 768 in³, and the definition of the volume is:
Where:
- V is the volume
- A is the area (A=8*12 in²)
- h is the height
So
Now, we know that the storage cube has a length of 4 in so we have a volume equal to 64 in³. Therefore we just need to divide 768 in³ by 64 in³ it is 12.
Finally, 12 cubes can fit in the create.
I hope it helps you!
