You are a volcanologist studying a recently active volcano. You need to get as close to the volcano as possible, but the tempera

ture rises the closer you get, and your instruments will only function properly if the temperature is below 105°. In order to get accurate information about the area, you need to be within 500 feet from the base of the volcano. You have taken the following preliminary measurements:
5200 feet away the air temperature is 77°
4100 feet away the air temperature is 82°
3200 feet away the air temperature is 87°
2300 feet away the air temperature is 93°
1900 feet away the air temperature is 97°

If we use Temperature as the independent variable and Distance is the dependent variable, the equation y = -165x+17700, models the Distance (in feet) you are from the volcano as a function of the air temperature (in degrees Fahrenheit). Use this equation to answer the following questions.

a - What label would you put on the x-axis of a graph, distance or temperature? Why?
b - What label would you put on the y-axis? Why?
c - What is the domain and range of the situation? Why?
d - Predict the distance from the volcano when the air temperature is 100 degrees.
e - Predict the air temperature when you are 1000 feet from the volcano.
f - Given this information, would you guess the temperature will be too hot to do your research when you are within 500 ft of the volcano

Answer:

The answer is 131 people

Step-by-step explanation:

I'm not too sure about equations bc its been a min since I've done them but maybeeeee it's 26x - (1,575) = 5,000 something like that LOL

All I know is that you have to subtract 1575 from 5,000 and then you get 3,435 dollars left and you divide that by 26 people and you get 131.731 but of course you can't have a half of person so it stays at 131.

Hopefully that helped lol

Alik [6]

Answer:The value of the bulldozer after 3 years is $121950

Step-by-step explanation:

We would apply the straight line depreciation method. In this method, the value of the asset(bulldozer) is reduced linearly over its useful life until it reaches its salvage value. The formula is expressed as

Annual depreciation expense =

(Cost of the asset - salvage value)/useful life of the asset.

From the given information,

Useful life = 23 years

Salvage value of the bulldozer = $14950

Cost of the new bulldozer is $138000

Therefore

Annual depreciation = (138000 - 14950)/ 23 = $5350

The value of the bulldozer at any point would be V. Therefore

5350 = (138000 - V)/ t

5350t = 138000 - V

V = 138000 - 5350t

The value of the bulldozer after 3 years would be

V = 138000 - 5350×3 = $121950

You just add the values for volunteers that worked 16-20 hours and 21-25 hours which would be 50 + 10 = 60. So the total number of volunteers that workers more than 15 hours is 60.
