Final answer:
In this case, the rate of change in energy consumption from 2015 to 2019 is 35.5 quadrillion Btu per year.
The answer is option ⇒5
Step-by-step explanation:
To find the rate of change in energy consumption from 2015 to 2019, we need to calculate the difference between the energy consumption in 2019 and 2015. The rate of change can be determined by dividing this difference by the number of years between the two years.
Given:
- Energy consumption in 2019 = 563 quadrillion Btu
- Energy consumption in 2015 = 421 quadrillion Btu
Difference in energy consumption = 563 quadrillion Btu - 421 quadrillion Btu = 142 quadrillion Btu
Number of years between 2015 and 2019 = 2019 - 2015 = 4 years
- Rate of change = Difference in energy consumption / Number of years
- Rate of change = 142 quadrillion Btu / 4 years
Calculating this expression gives us:
Rate of change = 35.5 quadrillion Btu per year
Therefore, the rate of change in energy consumption from 2015 to 2019 is 35.5 quadrillion Btu per year.
The answer is option ⇒5) 35.5 quadrillion Btu per year
Your question is incomplete, but most probably the full question was:
Supposed it is expected that 563 quadrillion thermal units of Btu (British thermal units) of energy will be consumed worldwide in 2019. In 2015, worldwide consumption was 421 quadrillion Btu. What is the rate of change in energy consumption from 2015 to 2019 in quadrillion Btu?(what is rate of change?)
- 1: 6.74 quadrillion Btu per year
- 2: 0.74 quadrillion Btu per year
- 3: 96.60 quadrillion Btu per year
- 4: 90.86 quadrillion Btu per year
- 5: 35.5 quadrillion Btu per year
