Can a local maximum also be a point of inflection? Explain.

1 answer:

7 0

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.

What is the correct answer to this multiple choice question? Please help!

erik [133]

Answer:

$\sqrt[3]{4}$

Step-by-step explanation:

To solve this we need to take the square root of both sides with a certain degree.

$4^6 = a^{18}$

We can take the root of both sides with a degree of 18.

$\sqrt[18]{4^6} = \sqrt[18]{a^{18}} \\(4^6)^{\frac{1}{18} } = a\\a = 4^{\frac{6}{18} } = 4^{\frac{1}{3} } = \sqrt[3]{4}$

It's helpful to understand that when a number has its square root taken with some degree n. The square root can be represented as just the value raised to the (1/n) power.

It's also helpful to understand that when you raise something to the power of another power, you can simply multiply the powers together. For instance (2^3)^5 = 2^15

A line has a slope of -4 and includes the points (-3, p) and (-4,0). What is the value of p?

emmainna [20.7K]

Answer:

p = - 4

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to - 4

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 3, p ) and (x₂, y₂ ) = (- 4, 0 )

m = $\frac{0-p}{-4-(-3)}$ = $\frac{-p}{-4+3}$ = $\frac{-p}{-1}$ = p = - 4

The mean is a better descriptor for skewed distribution. a. true b. false

vitfil [10]

Most likely true. It depends. When the distribution is skewed with an extreme tilting it to one side, median would be a better measure of central tendency. If the extremities are almost balanced on both sides then mean would be a better measure of central tendency.
