ANSWER
The first three expressions will simplify to a rational answer.
EXPLANATION
Let us simplify the expressions then we can see which of them are rational.
A.
We multiply out the roots to get
This simplifies to
This is a rational number hence the answer is rational.
B.
This is also a rational solution.
C.
This one too is a rational solution.
D.
This is an irrational answer because √3 is an irrational number and multiplying a rational number, 4 by an irrational number results in an irrational number.
Answer:
x= y=5-
Step-by-step explanation:
x+y=5
y=5-x
x-y=a
x-(5-x)=a
2x-5=a
2x=a+5
x=
x+y=5
+y=5
y=5-
Answer:
The probability that the first song will be a pop song is 3/10
Step-by-step explanation:
Number of rock songs = 12
Number of pop songs = 15
Number of oldies songs = 10
Number of hip hop songs = 13
Total Number of songs = 12+15+10+13=50
So,the probability that the first song will be a pop song =
Hence the probability that the first song will be a pop song is 3/10
The Reactance of a Capacitor is t<u>he resistance it has when alternating current (A/C) with a specific frequency (f) passes through it. </u>This is measured in ohms (Ω) and its formula is:
(1)
Where:
is the Reactance in ohms (Ω)
is the frequency of the alternating current in Hertz ()
is the Capacitance of the Capacitor in Farad ()
In this case we have a 25 mF capacitor with an applied frequency of 400 Hz.
Note
Well, with the given data we have to solve (1):
Then:
XC=0.0159 Ω This is the Reactance of the Capacitor
