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
The speed in feet per second may be calculated by the proper dimensional analysis and the given conversion factors. That is,
(40 mile / hr) x (5280 feet / 1 mile) x (1 hr / 3600 s) = 58.67 ft / s
Thus, the Jackrabbits' speed may also be expressed as 58.67 ft / s.
Answer:
B
Step-by-step explanation:
The domain is all the possible values of x. The graph starts at x=-2 and continues to positive infinity, so x ≥ -2.
Answer B.
IfIf it forms interior <6 measuring70. The measure of <4 is: B. 110°.
<h3>Measure of <4</h3>
Using this interior angle theorem
Measure of <4=180° - <6
Where:
<6 measure 70
Hence:
Measure of <4=180°-70°
Measure of <4=110°
Therefore the measure of <4 is: B. 110°.
