Условие

The air pressure at sea level (0 km altitude) is about 1000 hPa (hectopascal). The higher you rise in the Earth’s atmosphere, the lower is the air pressure: it decreases by 13% per kilometer. Choose the equation that describes the relation between the altitude xx and the air pressure yy.

  1. y=0.87⋅xy = 0.87 \cdot x
  2. y=1000⋅0.87xy = 1000 \cdot 0.87^x
  3. y=x1.13y = x^{1.13}
  4. y=1000⋅1.13xy = 1000 \cdot 1.13^x
