Find the second derivative of the function.
Answer
The second derivative of an implicit function can be found using sequential differentiation of the initial equation F(x,y)=0. At the first step, we get the first derivative in the form y′=f1(x,y). On the next step, we find the second derivative, which can be expressed in terms of the variables x and y as y′′=f2(x,y).

Answer:
B. 6 x 0.8
Step-by-step explanation:
It depends on the placement of the decimal point. All of the answers have 6 x 8. It's just that the decimal points are in different places each time.
For example, option A, is 6 x 8, which is 48. 48 is not equal to 4.8.
Option B, however, has 6 x 0.8. 6 x 8 = 48, and divided by 10 is 4.8. 4.8 = 4.8. This means Option B is correct.

Answer:
hurricane basics
Step-by-step explanation:
A "hurricane" is the most severe category of the meteorological phenomenon known as the "tropical cyclone."
Tropical cyclones are low pressure systems that have thunderstorm activity and rotate counterclockwise. A tropical
cyclone that has winds of 38 mph (33 kt) or less is called a tropical depression. When the tropical cyclone's winds reach
39-73 mph (34-63 kt), it is called a tropical storm. When the winds exceed 74 mph (64 kt), the storm is considered
to be a hurricane.
The Saffir-Simpson Hurricane Scale defines hurricane strength by categories. A Category 1 storm is the weakest hurricane
(winds 74-95 mph or 64-82 kt); a Category 5 hurricane is the strongest (winds greater than 155 mph or 135 kt).
The category of the storm does not necessarily relate directly to the damage it will inflict. Lower category storms (and
even tropical storms) can cause substantial damage depending on what other weather features they interact with, where
they strike, and how slow they move.
Anatomy of a Hurricane
Typical hurricanes are about 300 miles wide although they can vary considerably in size.
The eye at a hurricane's center is a relatively calm, clear area approximately 20-40 miles across.
The eyewall surrounding the eye is composed of dense clouds that contain the highest winds in the storm.
The storm's outer rainbands (often with hurricane or tropical storm-force winds) are made up of dense bands of
thunderstorms ranging from a few miles to tens of miles wide and 50 to 300 miles long.
Hurricane-force winds can extend outward to about 25 miles in a small hurricane and to more than 150 miles for a large
one. Tropical storm-force winds can stretch out as far as 300 miles from the center of a large hurricane.
Frequently, the right side of a hurricane is the most dangerous in terms of storm surge, winds, and tornadoes.
A hurricane's speed and path depend on complex ocean and atmospheric interactions, including the presence or absence
of other weather patterns. This complexity of the flow makes it very difficult to predict the speed and direction of a hurricane.
Do not focus on the eye or the track–hurricanes are immense systems that can move in complex patterns that are difficult
to predict. Be prepared for changes in size, intensity, speed, and direction.

Step-by-step explanation:
A man bought a certain number of golf balls for RM 20. If each ball has costed 20 cents less, he could have bought five more for the same money. How many golf balls did he buy?
Answer:
He bought 20 balls
Step-by-step explanation:
Cost of a certain number of golf balls = $20
Let 1 golf ball cost $x
This means number of balls bought = 20 / x
If each ball has costed 20 cents less;
Converting 20 cents to dollars = $0.2
$x - $0.2
he could have bought five more for the same money.
Number of balls = 20/x + 5
Using the formulae;
Cost of 1 ball * Number of balls bought = Amount spent
(x-0.2) (20/x + 5) = 20
Expanding the expression;
x(20/x + 5) - 0.2(20/x + 5) = 20
20 + 5x - 4/x - 1 = 20
19 + 5x - 4/x = 20
5x - 4/x = 1
Multiplying all through by x
5x^2 - 4 = x
5x^2 - x - 4 = 0
(5x + 4)(x - 1) = 0
x = 1 or -4/5
-4/5 is unrealistic hence the correct value is;
x = $1
He bought 20 balls; 20 / x = 20 / 1 = 20
The reduction in the price of each ball increases the number of balls the man can buy at RM 20.
The number of balls he bought is 20 balls.
Reasons:
The given parameters are;
The amount the man bought the golf balls = RM 20
The number of golf balls he could have bought if each ball costs 20 cents less = 5 more balls
Let the number of balls the man bought = x
Let the price of each ball be m
We have;
m × x = 20
(x + 5)·(m - 0.20) = 20
Therefore, we get;
[tex]m = \dfrac{20}{x}[/tex]
Which gives;
[tex]\left(x + 5 \right) \cdot \left(\dfrac{20}{x} - 0.20\right) = 20[/tex]
[tex]-\dfrac{\left(0.2 \cdot x^2- 19 \cdot x - 100\right)}{x} = 20[/tex]
20·x = -0.2·x² + 19·x + 100
0.2·x² + x - 100 = 0
x² + 5·x - 500 = 0
(x + 25)·(x - 20)
x = 20
The number of balls he bought, x = 20 balls

Required:
a. Calculate the mean and the median ERAs for the New York Yankees.
b. Calculate the mean and the median ERAs for the Baltimore Orioles.
c. Based solely on your calculations above, which team is likely to have the better winning record?
1. New York Yankees
2. Baltimore Orioles
Answer:
(a): [tex]\bar x = 5.54[/tex] and [tex]Median = 4.86[/tex]
(b): [tex]\bar x = 5.27[/tex] and [tex]Median = 5.21[/tex]
(c): New York Yankees
Step-by-step explanation:
Given
Data of New York ERA and Baltimore ERA
Solving (a): Mean and Median of New York ERA
Mean is calculated as:
[tex]\bar x = \frac{\sum x}{n}[/tex]
For New York ERA, n = 19. So, we have:
[tex]\bar x = \frac{3.13 + 2.88 + 4.99 + 3.99 + 4.68 + 5.80 + 6.81 + 0.98 + 4.86 + 5.93 + 2.88 + 3.92 + 4.08 + 3.00 + 7.50 + 9.00 + 5.40 + 7.36 + 18.00}{19}[/tex]
[tex]\bar x = \frac{105.19}{19}[/tex]
[tex]\bar x = 5.53631578947[/tex]
[tex]\bar x = 5.54[/tex]
To calculate the median value, we first arrange the data (in ascending order):
So, we have:
0.98, 2.88, 2.88, 3.00, 3.13, 3.92, 3.99, 4.08, 4.68, 4.86, 4.99, 5.40, 5.80, 5.93, 6.81, 7.50, 7.36, 9.00, 18.00
The median value of odd number of data is:
[tex]Median = \frac{1}{2}(n+1)\ th[/tex]
Substitute 19 for n
[tex]Median = \frac{1}{2}(19+1)\ th[/tex]
[tex]Median = \frac{1}{2}(20)\ th[/tex]
[tex]Median = 10th[/tex]
So, the median is the 10th item.
[tex]Median = 4.86[/tex]
(b): Mean and Median of Baltimore ERA
Mean is calculated as:
[tex]\bar x = \frac{\sum x}{n}[/tex]
For Baltimore ERA, n = 17. So, we have:
[tex]\bar x = \frac{4.58+ 5.77+ 5.21+ 6.51+ 4.29+ 2.50+ 5.23+ 4.31+ 4.87+ 3.14+ 2.57+ 7.92+ 7.79+ 5.40+ 2.92+ 10.13+ 6.52}{17}[/tex]
[tex]\bar x = \frac{89.66}{17}[/tex]
[tex]\bar x = 5.27411764706[/tex]
[tex]\bar x = 5.27[/tex] --- approximated
Arrange in ascending order:
2.50 , 2.57 , 2.92 , 3.14 , 4.29 , 4.31 , 4.58 , 4.87 , 5.21, 5.23 , 5.40 ,5.77 , 6.51 , 6.52, 7.79 , 7.92 , 10.13
[tex]Median = \frac{1}{2}(n+1)\ th[/tex]
[tex]Median = \frac{1}{2}(17+1)th[/tex]
[tex]Median = \frac{1}{2}(18)th[/tex]
[tex]Median = 9th[/tex]
So, the median is the 9th item.
[tex]Median = 5.21[/tex]
(c): Who has a better record
Statistically, the average ERA of New York Yankees is better than the average ERA of Baltimore Orioles.
Hence, New York Yankees hold the better record
