What is the change in temperature from 20 degrees to -8 degrees ?

Answer:

time and weather data is dis right

Step-by-step explanation:

Step-by-step explanation:

Weather forecasting is the application of science and technology to predict the conditions of the atmosphere for a given location and time. People have attempted to predict the weather informally for millennia and formally since the 19th century. Weather forecasts are made by collecting quantitative data about the current state of the atmosphere at a given place and using meteorology to project how the atmosphere will change.

Once calculated by hand based mainly upon changes in barometric pressure, current weather conditions, and sky condition or cloud cover, weather forecasting now relies on computer-based models that take many atmospheric factors into account.[1] Human input is still required to pick the best possible forecast model to base the forecast upon, which involves pattern recognition skills, teleconnections, knowledge of model performance, and knowledge of model biases. The inaccuracy of forecasting is due to the chaotic nature of the atmosphere, the massive computational power required to solve the equations that describe the atmosphere, the error involved in measuring the initial conditions, and an incomplete understanding of atmospheric processes. Hence, forecasts become less accurate as the difference between current time and the time for which the forecast is being made (the range of the forecast) increases. The use of ensembles and model consensus help narrow the error and pick the most likely outcome.

There is a vast variety of end uses to weather forecasts. Weather warnings are important forecasts because they are used to protect life and property. Forecasts based on temperature and precipitation are important to agriculture, and therefore to traders within commodity markets. Temperature forecasts are used by utility companies to estimate demand over coming days. On an everyday basis, many use weather forecasts to determine what to wear on a given day. Since outdoor activities are severely curtailed by heavy rain, snow and wind chill, forecasts can be used to plan activities around these events, and to plan ahead and survive them. In 2009, the US spent approximately $5.1 billion on weather forecasting.[2]

Answer:

  G = (2, -1)

Step-by-step explanation:

You want ...

  FG/FH = 1/6 = (G -F)/(H -F)

  H -F = 6(G -F)

  H +5F = 6G . . . . . . add 6F, simplify

  G = (H +5F)/6 . . . . .divide by 6

Substituting the given coordinates, we get ...

  G = ((-8, 19) +5(4, -5))/6 = (-8+20, 19 -25)/6 = (12, -6)/6

  G = (2, -1)

Answer:

81 square ft

Step-by-step explanation:

square B has a site lenght of 15ft

therefore square must have one of 3/5 of 15 which is 9

the area is 9x9=81

a)

The rotation transformations are:

[tex] x=x' \cos \theta - y' \sin \theta\\

y= x' \sin \theta + y' \cos \theta[/tex]

where $(x', y')$ are new coordinates.

Since we want an anti-clockwise rotation of the axes, put $\theta= 90$° to get the required coordinates as $(4,-1)$

b)

The equation of the given line is $x-y=0$

Use the mirror formula:

[tex] x'= x_o - \frac{2 a}{a^2+ b^2}(a x_o + by_o +c)[/tex]

Replace $x$ by $y$ above to get the corresponding formula for the y-coordinate.

Here we have

$a=1$

$b=-1$

$c=0$

$x_o= 1$

$y_o =4$

Substitute these values to get the required coordinates as $(4,1)$

c)

$(5,3)$ maps onto $(1,1)$

Let's keep it simple here: To get the new coordinates you subtract 4 from the x coordinate and 2 from the y coordinate.

Thus for our point $(1,4)$ our image is $(1-4, 4-2)$ which is $(-3,2)$

Answer:

x = 7 / 2

Step-by-step explanation:

5(2x - 9) + 3 = -7    ---------- subtract 3 from both sides

5(2x - 9) + 3 - 3 = -7 - 3

5(2x - 9) = -10   ------ divide both side by 5

2x - 9 = -2      ---------- add 9 to both sides

2x - 9 + 9 = -2 + 9

2x = 7

x = 7 / 2

Answer:

The line on the graph would be a flat line

Step-by-step explanation:

The line would not move up or down at all.

Answer:

A graph having a constant rate of change equal to zero means that the value of y is constant. A graph with slope zero is a horizontal line.

Answer:

59 degrees and 31 degrees.

Step-by-step explanation:

Complementary angles form a 90 degree angle. Let's say that one angle measures x degrees. If one angle is x degrees, the other measures 28 degrees less. So, the other measures x - 28 degrees.

x + (x - 28) = 90

2x - 28 = 90

2x = 118

x = 59 degrees.

The other angle measure will then be 59 - 28 = 31 degrees.

Hope this helps!

Answer:

59°  and   31°

Step-by-step explanation:

Complementary angle sum 90°

a + b = 90

a = b - 28

then:

(b - 28) + b = 90

2b - 28 = 90

2b = 90 + 28

2b = 118

b = 118/2

b = 59°

a = b - 28

a = 59 - 28

a = 31°

Probe:

59° + 31° = 90°

Hey there! I'm happy to help!

When looking for a conclusion, we have to find something that we can figure out from the information but they don't directly tell us.

Answer B says that a conclusion is that the lines meet at a 90 degree angle, but they already told us that, so this is wrong.

Answer C does the same thing, so it is wrong as well.

A 90 degree angle is a right angle. They already told us that the lines intersect at a right angle, so this is not a conclusion.

Answer A says that the lines are perpendicular. They don't directly tell us that these specific lines are perpendicular, but from the information they gave us we can figure it out. Therefore, the correct answer is A. The lines are perpendicular.

Have a wonderful day! :D

Answer: Whether or not they are registered with FINRA.

Step-by-step explanation: When evaluating an investment advisor, it is important to evaluate their level of experience, educational background as it goes a long way in giving clients a clue of the advisors possible offering, knowledge and expertise. Additionally, an Investment advisor should be registered with the Security and Exchange Commission (SEC), which is a federal regulatory agency charged with making regulatory policies that aid investor protection and proper market functioning. Being registered with FINRA, Financial Industry Regulatory Authority is not really to be considered as it is a self regulatory body (that is non governmental) and the main rules and policies guiding the market are made by SEC.

Answer:

We need 144 birthday candles do you need for the 12 parties.

Step-by-step explanation:

We are given that you are a caterer specializing in children's birthday parties. You have 12 birthdays to cater to next week. You must bake 2 cakes for each party. Each cake will have 6 candles on it.

And we have to find the birthday candles we need for the 12 parties.

AS it is stated that next week you have 12 birthday parties and for each birthday party you must bake 2 cakes.

This means that for 12 birthday parties you have to make = [tex]12 \times 2[/tex] = 24 cakes.

Also, each cake has 6 candles on it. This means that the total number of candles for 24 cakes = [tex]24 \times 6[/tex] = 144 candles.

Hence, we need 144 birthday candles for the 12 parties.

Answer:

10: -11n^5

12: 6k^2 -6k+7

Step-by-step explanation:

Ok so what your gonna do is add or subtract the ones with the same exponent.

so -15+4= -11 since they are both n^5 you can add them so your answer is:

-11n^2

now you have 8k^2-k-5k+7-2k. so you are gonna rearrange them so the same exponents are together.(keep the sign in front in front, if no sign it is positive)

8k^2-2k^2-5k-k+7

add like exponents

6k^2-6k+7

Step-by-step explanation:

===================================================

Work Shown:

Use the slope formula to get

m = (y2 - y1)/(x2 - x1)

m = (0 - (-3))/(9 - 0)

m = (0 + 3)/(9 - 0)

m = 3/9

m = 1/3

----------------

Basically we subtract the y coordinates, and do the same for the x coordinates as well (subtract in the same order). Afterward, divide the two results. Reduce the fraction as much as possible.

A slope of 1/3 means we move up 1 unit each time we move to the right 3 units.

The slope being positive means the line goes uphill as you read from left to right.

Answer:

Step-by-step explanation:

The sequence of amounts in Jackson's account will be ...

  7440, 7320, 7200, ...

with a first value (a1) of 7440 and a common difference (d) of -120.

The recursive formula for an arithmetic sequence is ...

  a[1] = a1

  a[n+1] = a[n] +d

For our sequence, the recursive formula is ...

  a[1] = 7440

  a[n+1] = a[n] -120

__

The explicit formula for an arithmetic sequence is ...

  an = a1 +d(n -1)

For our sequence, the explicit formula is ...

  a[n] = 7440 -120(n -1)
