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]

Can you please help me ASAP
kap26 [50]

Answer:

15°

Step-by-step explanation:

AB is parallel to DC and AD is parallel to BC

Therefore, if you put Angle D and Angle C together it must form 180°

If Angle C = 120°, that means Angle D = 60°

Now you subtract 45 from 60 and that gives you 15.

Evaluate log3^8, given log3^2 is equivalent to 0.631
elixir [45]

We will use the followin property of logarithms:


log(a^b) = b log(a)


So, we have


log(3^2) = 2 log(3) = 0.631


If you multiply both sides by 4, you get


8log(3) = log(3^8) = 2.524

If Jasper installs a floor himself, it will take him 7 hours. Working with Yolanda, it will take them 3 hours.
Svetllana [295]

Answer: 5\frac{1}{4} hrs

<u>Explanation:</u>

Jasper: \frac{1}{7} per hr

Yolanda: \frac{1}{x} per hr

Together: \frac{1}{3} per hr

Jasper + Yolanda = Together

\frac{1}{7} + \frac{1}{x} = \frac{1}{3}

(21x)\frac{1}{7} + (21x)\frac{1}{x} = (21x)\frac{1}{3}

3x + 21 = 7x

        21 = 4x

        \frac{21}{4} = x

         5\frac{1}{4}
