Answer:
-24xy+ 162x²y +168xy²
Step-by-step explanation:
[4-7(3x+4y)] • 3x(-2y) =
(4-21x-28y) • (-6xy)=
4•(-6xy) -21x•(-6xy)-28y•(-6xy)=
-24xy+ 162x²y +168xy²
Answer: y should be in the interval (0.4, 4)
Explanation:
The binomial 5y - 7 is in the interval (-5, 13) if and only if
-5 < 5y - 7 < 13
Solving the inequalities in this form is the same as solving equation. So, we add all sides of the inequalities by 7 so that
2 < 5y < 20
Then, we divide both sides by 5 to get the following inequalities
0.4 < y < 4
Hence y should be in the open interval (0.4, 4).
Answer:
Apparent power is 1.413Volt-Amps.
Step-by-step explanation:
We are given that in a parallel circuit,
,R=33kΩ and
=82kΩ.
And we are asked to find apparent power.
Apparent power is the combination of true power and reactive power.
In other words, we can say that in a power triangle apparent power is the hypotenuse where as true power and reactive powers are sides.
Let us find true power , reactive power first and the using Pythagorean theorem we can find apparent power.
True power=
Reactive power=
Hence apparent power=
Answer:
w = -20
Step-by-step explanation:
8-3=5
-w/4=5
5*4=20
-w=20
-1/20=-20
w=-20
