Answer:
12 dollars
Step-by-step explanation:
He spent 3/7 of 56
3/7*56 =24
Take the original amount and subtract what was spent
56-24 =32
He has 32 left
He spent 5/8 of that on a bat
5/8 *32 =20
Take the amount of money he had and subtract what was spent
32-20 = 12
He has 12 left
<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>
