Your answer would be the bottom right image. In the bottom right image, x is divided by 5 consistently. No function can be determined in the other tables.
Umm this should be in physics but F is proportional to 1/r^2 I am assuming you want to just take the derivative in respect to r of both sides of the equation
F = (2.99x10^16)/r^2
So you do that and you get
dF/dr = -2(2.99 * 10 ^16)/ (r^3)
is this for calc class?
1.) 35,000+6,000+65+13
2.) 25,000+ 16,000+11,000+78
The answer would be B. You would need to keep the first fraction, change to multiplication, and flip the second fraction and multiply across.
The bottom one
That should be correct!!!
