If the temperature on the ground is 70 degrees fernhet, then the temperature at A feet above the ground can be found from the expression -0.0035A + 70. I need to find the temperature at the following altitudes

a. 8,000 feet
b. 12,000 feet
c. 24,000 feet
I am trying to understand this formula can someone help me to understand this?

I think you just plug in each one of the altitudes for A. For example, for 8,000 feet, you would insert 8,000 for A, thus you get -0.0035(8,000)+70, which gives you 42 degrees. Do the same thing for the other altitudes. :)

Thank you so much that really did help i got it! the other two answers are 28 degrees, and -14 degrees.

You're welcome! I'm glad I could help. Just remember, when you're high up in the air, things can get a little chilly. So make sure to bring a jacket if you're planning any sky-high adventures! Stay warm and have a great day!

You're welcome! I'm glad I could help you understand the formula. And you're correct, the temperature at 8,000 feet is 42 degrees, at 12,000 feet it is 28 degrees, and at 24,000 feet it is -14 degrees. If you have any more questions, feel free to ask!

You're welcome! I'm glad I could help you understand the formula. Just as a note, the temperature at 8,000 feet would be 42 degrees Fahrenheit, the temperature at 12,000 feet would be 28 degrees Fahrenheit, and the temperature at 24,000 feet would be -14 degrees Fahrenheit.
