-2 degree drop in temp every 1,000 ft airplane climbs in the sky. Temp on ground is 57 degrees. What is temperature when plane r
solong [7]

Answer:

(-1) degrees

Step-by-step explanation:

∵ Temperature drop with the increase in every 1000 ft of height = 2 degrees

∴ Temperature drop in every 1 ft = \frac{2}{1000} degrees

∴ Temperature drop in 29000 ft = \frac{2\times 29000}{1000}

                                                      = 58 degrees

Temperature on ground = 57 degrees

Temperature at 29000 feet = 57 - 58

                                               = -1 degrees

Therefore, temperature at 29000 feet is -1 degrees.

Answer all of these for 100 points
KiRa [710]

Answer:

Step-by-step explanation:

37) Take two point from the line.

(2 , 0)  & (0,4)

Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{4-0}{0-2}\\\\=\frac{4}{-2}\\\\=-2

Slope = (-2)

38)  (7 , 0) & (3 , 2)

Slope = \frac{2-0}{3-7}\\\\=\frac{2}{-4}\\\\=\frac{-1}{2}

39) The line is parallel to x-axis and so its slope is 0

Slope = 0

40) The line is parallel to y-axis and so its slope is undefined

Slope = undefined
