The concavity of a function is described by its second derivative.

-The expression will not directly tell us whether the function is concave up or concave down and where it changes, though graphing the function may give us some sort of idea.

-The first derivative tells us the critical/important values (where there could be asymptotes), as well as where the function is increasing/decreasing.

-The second derivative tells us again the critical/important values, but also where the function is concave up/down. We find concavity in the same way we find increasing/decreasing using the first derivative.

-The third derivative, at least in my experience, has only been used to find acceleration of a function.

Hope this helps!! :)

The concavity of a function is described by its 2nd derivative

The concavity of a function is dependent on the rate of change of a function's derivative

Assume the derivative of a function is f'(x), so the second derivative would be represented as: f"(x)

When f"(x) > 0, then the function is concave downward.

However, if f"(x) < 0, then the function is concave upward.

Hence, the concavity of a function is described by its 2nd derivative

An example of a polynomial is:

2x^3 - 4x^2 +1x -8

Note how there are exponents, such as ^3 for example. There is also a variable, in this case x. Lastly, there are constants, which are numbers by themselves.

Answer:

Step-by-step explanation:

Always work from the inside out. That means we will deal with the parenthesis first: (4 - 1)

That gives us

2[32 - (3)³]. Next deal with the exponents. That gives us

2[32 - 27]. Next, the last set of parenthesis, which are actually brackets:

2[5] which then, finally, becomes 10

Answer: 3/11 would be the answer

Sum of the interior angles of any triangle equal 180 degrees , Thus :

A + B + C = 180

48 + B + 67 = 180

B + 115 = 180

B = 180 - 115

B = 65 degrees

Answer:

B = 65°

Step-by-step explanation:

Area of triangle,

→ 180° = A + B + C

→ 180° = 48° + B + 67°

→ 180° = 115° + B

→ B = 180° - 115°

→ B = 65°

Answer:

27000

Step-by-step explanation:

We want to round 27346 to 2 significant figures.

Now, the number already has 5 significant figures, so to reduce it to 2 sig figures, we will have to reduce the 3 digits from the right to zero so that we can have just 2 significant figures by approximating.

Thus, 3 is less than 5 and so 7 cannot increase. Thus, we will have 27000 as the number when reduced to 2 significant figures.

A number line is a horizontal line that has equally spread number increments. The points at A, B, C, D, E and F are -3.25, -4.5, 1.25, -5.75, 0.5 and -2.5

A number system is defined as a system of writing to express numbers. It is the mathematical notation for representing numbers of a given set by using digits or other symbols in a consistent manner.

A number line is a horizontal line that has equally spread number increments. The points at A, B, C, D, E and F are

15.) -3.25

16.) -4.5

17.) 1.25

18.) -5.75

19.) 0.5

20.) -2.5

Therefore the points at A, B, C, D, E and F are -3.25, -4.5, 1.25, -5.75, 0.5 and -2.5.

Answer:

Total apples=10

no.of honeycrisp Apple=2

1). Probability-2/10. =1/5

now total apples left=9

tolyal honey crisp apples left=1

2) probability=1/9

The Probability that Jerome pick a Honeycrisp apple out of his bag is 1/5.

The Probability the Jerome pick to choose another Honeycrisp apple out of his bag is 1/9.

Probability is "possibility that deals with occurrence random events".

According to the question,

Total number of apples = 10 apples

Total number of Honeycrisp apples = 2 apples

Formula for probability = [tex]\frac{Number of favorable events}{Total number of events}[/tex]

Probability that Jerome pick a Honeycrisp apple out of his bag = [tex]\frac{2}{10}[/tex] = [tex]\frac{1}{5}[/tex].

After taking one honey crisp apple remaining one left so subtracting one from total number of apples.

10 - 1 = 9

Probability that Jerome pick to choose another Honeycrisp apple out of his bag = 1/9.

Hence, the Probability that Jerome pick a Honeycrisp apple out of his bag is 1/5.

The Probability the Jerome pick to choose another Honeycrisp apple out of his bag is 1/9.

Answer:

Step-by-step explanation:

P(starts with M wins presidency) = required outcome / Total possible outcomes

Number of names which starts with M = 1

Total number of names = 5

P(starts with M wins presidency) = 1/ 5

For vice presidency :

Number of names which starts with M = 0

Total number of names = 4

P(starts with M wins vice presidency) = 0/4

P(name which starts with M wins presidency and vice presidency) = 1/5 * 0/4 = 0

Using the Empirical Rule, the percentage of students who scored greater than 700 is:

b. 2.5%

It states that, for a normally distributed random variable:

700 is two standard deviations above the mean. 5% of the measures are more than two standard deviations of the mean. Since the normal distribution is symmetric, 2.5% of these measures are below 300 and 2.5% are above 700, hence option B is correct.

Answer:

1725.1 feet

Step-by-step explanation:

It is given that there is a right angled triangle having a base of length of 130 feet. The angle between the hypotenuse and the base is given as 85.691 degrees.

Therefore, to find the height, we know :

[tex]$\tan \theta = \frac{\text{height}}{\text{base}}$[/tex]

[tex]$\tan 85.691 = \frac{\text{h}}{\text{130}}$[/tex]

[tex]$13.27 = \frac{\text{h}}{\text{130}}$[/tex]

h = 13.27 x 130

  = 1725.1 feet

Therefore, the height of the Eiffel tower =  1725.1 feet
