Answer:
$187.61
Step-by-step explanation:
Data provided:
Temperature of the heat exchanger, Tc = 2° C = 273 + 2 = 275 K
Temperature of the base board radiators , Th=47° C = 273 + 47 = 320 K
Cost of heating the house = $1000
Coefficient of performance of the heat pump = 75% = 0.75
Now,
Actual performance = 75% of performance of heat pump
or
Actual performance = 0.75 ×
or
Actual performance = 0.75 ×
or
Actual performance = 0.75 ×
or
Actual performance = 5.33
Therefore, the cost =
or
cost = $187.61
Answer:
Step-by-step explanation:
The range of the function is what values of y from lowest to highest that are covered by the function. The domain are the values on the left: A-E; the range are the values on the right: 1-3. We state both domain and range in interval notation, stating only the lowest and highest values in either a set of brackets if the values are included, a set of parenthesis if the values are not included, or a mixture of both. Our range is inclusive, so we mention the lowest and the highest only: [1, 3].
7 1/2 - 1 1/4 = 7 2/4 - 1 1/4 = 6 1/4
