Answer:
y=-x^2 is just y=x^2 reflected over the x-axis. In other words, the parabola is upside-down.
Step-by-step explanation:
2100/1 or 4200/2, could be either
Answer: 91,445,760 ft³
Step-by-step explanation:
You know that the base of this pyramid is a square, then you can use the following formula to calculate its volume:

Where "s" is the lenght of any side of the base of the pyramid and "h" is the height of the pyramid.
You know that:

Then, you can substitute these values into the formula. So, you get that the volume of The Great Pyramid is:

The factor of mn+5m-3n-15 is 6m-4n-15.
Using Pythagoras’ theorem a2 + b2 = c2 you can find out the third (longest) side. (6x6) + (8x8) = 100 (the square root of 100 is 10) so ur final sum is 6+8+10 = 24 mm
