<span>Inflection points are where the function changes concavity. Since concave up corresponds to a positive second derivative and concave down corresponds to a negative second derivative, then when the function changes from concave up to concave down (or vise versa) the second derivative must equal zero at that point. So the second derivative must equal zero to be an inflection point. But don't get excited yet. You have to make sure that the concavity actually changes at that point.</span>
The answer is 313.56 because 289 + (8.5%=24.65)=313.56
One car 1c
six bicycles 6b
two motorcycles
1c+6b+2m=9cbm
I think this is right but its been forever since i had to do these so
