<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>
So the problem ask to calculate and covert the said equation or expression to the form of ca^pb^q where as all of the variables is a number. So base in that information and following some formula, the answer would be a^(-3/2)b. I hope you are satisfied with my answer
Answer:
$24.50
Step-by-step explanation:
60% of $50= $30
$50-$30= $20
15% of $20= $4.50
$20+$4.50= $24.50
1/4 × 1/2 multiply 1/2 by 2 to get 2/4 then add 1/4 and 2/4 ur answer 3/4 the fraction of all the cookies that is peanut butter is 3/4
