<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>
Answer:
The correct approach is "-62". A further explanation is described below.
Explanation:
- A dependent variable could be seen since the blackheads become triggered whenever some substance or material is deposited between some of the teeth.
- Humans don't brush their teeth frequently, but there is still a significant possibility of decay, so cavities differ depending upon whether the specific teeth become brushed.
Answer:
We know that in a triangle, if two angles have equal measures, then the sides opposite to them are equal in length. Thus, the length of side AB is 6 units

Answer:
a = 104
Step-by-step explanation:
The sum of the angles round a point is 360°
Sum the 4 angles and equate to 360, that is
126 + a + 26 + a = 360, that is
2a + 152 = 360 ( subtract 152 from 360 )
2a = 208 ( divide both sides by 2 )
a = 104
