Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identity
• tan²x + 1 = sec²x
⇒ tan²x - sec²x = - 1
Thus the derivative reduces to
( - 1 ) = 0
<em>zero product property (Angela)</em>
- Step-by-step explanation:
<em>Hi there ! </em>
<em> (Angela)</em>
<em>3x² + 10x = 0</em>
<em>x(3x + 10) = 0</em>
<em>x = 0 => x₁ = 0</em>
<em>3x + 10 = 0 => 3x = - 10 => x₂ = - 10/3 = - 3 1/3</em>
<em>Good luck !</em>
Answer:
the heat output from the condenser (Q) is compared to the power supplied to the compressor (W). COP is defined as the relationship between the power (kW) that is drawn out of the heat pump as cooling or heat, and the power (kW) that is supplied to the compressor.

2+3i
------ should be multiplied (numerator and denominator both) by 2+i. This will
2-i remove i from the denominator.
(2+3i) 2+i 4 + 2i + 6i - 3 1 + 8i
-------- * ----------- = ---------------------- = ---------- (answer)
2-i 2+i 4+(-1) 8
You could also write this as (1/8) + i.
