Question

Suppose there is a 1.4°F drop in temperature for every thousand feet that an airplane climbs into the sky. If the temperature on the ground is 55.4°F​, what will be the temperature when the plane reaches an altitude of 10,000 ft​?

The temperature will be ___°F ​(Type an integer or a​ decimal.)

Answer 1

Answer:41.1

Step-by-step explanation: first make an equation (y=-1.4x+55.4). Then, plug in the height, (because it’s every 1,000 feet temp changes you count by thousands). Solve the new equation f(10)=-1.4(10)+55.4 f(10)=41.4. F(10) means replace x by 10
