Answer:

Step-by-step explanation:
has the following properties:

º = 1.75 π (π = 180º)
therefore, z₁ = 13 * [ cos(1.75 π) + i sin(1.75 π) ] = 13*[cos(1.75π - 2π) + i sin(1.75π - 2π)] = 13*[cos(-π/4) + i sin(-π/4)] {this is due to periodicity} = 13*(√2/2 - i √2/2) = 
Answer:
Click the second and last one.
Step-by-step explanation:
For this case the first thing you should know is the following unit conversion.
1 BTU = 0.25 Kilocalories
We then have the following numerical value:

Applying the conversion of units we have:

Canceling units we have:
Answer:
This is 20000 kilocalories per hour
Answer:
