Answer: The correct requirement for a black hole to form is:
C. The star must be 10 to 28 times larger than Earth’s sun, and a supernova explosion must have occurred.
Explanation: The least star that is larger than the sun is 10 times larger and a supernova explosion would have happen before a black hole to form.
Heat energy would be the fuel for a hurricane. Also the warmer the water is, there is more moisture in the air, which can lead to even larger and stronger hurricanes
Smaller scale has less variables and correlations to be based on while a larger scale has a bigger amount of mathematical numbers to be based on
Answer:

Explanation:
y=2x-5
y=mx+b
perpendicular = slope is -1
y=-1/2x+b
Passes throught 2,-5
-5=-1/2(2)+b
-5=-1+b
b=-4
y=-1/2x-4
Hope this helps!
