Step-by-step explanation:
<u>Answer</u>-
<em>The total capacitive reactance of the circuit is </em><em>7.96 Ω.</em>
<u>Solution-</u>
Two capacitors, a 20 mF and a 30 mF, are connected in parallel to a 400 Hz source.
The effective/equivalent capacitance of the circuit is,
As, when capacitors are connected together in parallel, the equivalent capacitance in the circuit is equal to the sum of capacitance of all the individual capacitor.
We know that,
Where,
= Capacitive Reactance (in Ω)
f = frequency (in Hz)
C = Capacitance (in F)
Here given,
= ??
f = 400 Hz
C = 50 mF = 
F
Putting the values in the formula,
Therefore, the total capacitive reactance of the circuit is 7.96 Ω.
Answer:
w=-1.16u
Step-by-step explanation:
first you want to put the W's on one side and the U's on the other. we can do this by subtracting 4u from the left side and the right side making the equations 8w=-7u+2w.
next we want to subtract 2w from both sides making the equation 6w=-7u then we divide by 6 to get w=-1.16u
If we want to stretch graph vertically we need to multiply function f(x) with a number greater than 1. By doing so we will for same difference of x get larger difference of F(x) which means function will be stretched.
If we want to flipp over x axis function F(x) all we need to do is to multiply it by -1. Function will change its sign thus for same values of x we will get value of F(x) with oposite sign which means function will be flipped over x axis.
Looking at offered answers we can say that A and B arent answer because we didnt multiply function with number greater than 1.
Answer is C) G(x) = -4x^2
Answer:
The number is 8.
Step-by-step explanation:
If the positive number is x then:
x^2 = 5x + 24
x^2 - 5x - 24 = 0
(x - 8)(x + 3) = 0
x =8, -3 .
x is positive so the answer is 8.
