How do you factor 9xsquared-28x plus 20?
9x2 - 28x + 20 = 9x2 - 18x - 10x + 20 = 9x(x - 2) - 10(x - 2) = (9x - 10)*(x - 2)
How will an increase in amplitude and power affect dB?
The decibel (dB) scale is logarithmic. An increase of power by a factor of 10 is an increase of +10 dB. If power increases by a factor of 100, that is equivalent to +20 dB.The decibel (dB) scale is logarithmic. An increase of power by a factor of 10 is an increase of +10 dB.

What does 40 to the second power equal?
20
How do you factor 4x to the second power minus 20x plus 25?
4x2-20+25 = (2x-5)(2x-5) when factored with the help of the quadratic equation formula.
What is your opinion whether a low power factor can damage 20 watt led lights installed in a hotel?
The load (in this case, your led lighting) determines its own power factor. While you can improve the power factor (move it towards unity) at the terminals, you are not actually changing the power factor of the load.
Is -20 to the second power equal to -400?
380
What is the log of 20 to the second power is?
log(202) = 2log(20) = 2*1.30103 = 2.60206
Convert 20 kva to kw?
Your question cannot be answered, unless the power factor of the load is specified. Since true power(measured in watts) is the product of apparent power(measured in volt amperes) and the power factor of the load.So, given your figure of an apparent power of 20 kV.A(not 'kva'*), the corresponding value of true power could (theoretically!) range from20 kW at a power factor of 1.0, to0 kW at a power factor of 0.(*The correct symbol for kilovolt ampere is 'kV.A', not 'kva', and the correct symbol for kilowatt is 'kW', not 'kw'.)
What is 20 to the 2nd power?
20 to the second power is more commonly known as 202 or 20 squared. Squaring is calculated by taking two of the number and multiplying them together. In this case, 20x20=400 and so 20 to the 2nd power is 400.
What is 20 to the second power?
It equals 200 because 20x20 equals 200
What is 20-1-6-2 to the second power?
(20-1-6-2)2 = 112 = 121
What is the sum of second power of 4 and second power 2?
Calculate the powers, and do the addition. For example, the second power of 4 is the same as 4 x 4 (you are supposed to multiply 4 by itself).
