Answer:
Well t find the area of a triangle, you need to multiple Base x height. That gives you 43.56. Now you divide by 2. So the end product will give you 21.78. Those same rules apply to every time you are finding the area of a triangle.
Step-by-step explanation:
<u>Answer</u>-
<em>The total capacitive reactance of the circuit is </em>442.10<em> Ω.</em>
<u>Solution-</u>
Three capacitors, a 12 mF, a 20 mF, and a 30 mF, are connected in series to a 60 Hz source.
The effective/equivalent capacitance of the circuit is,
When capacitors are joined in series, the total value of capacitance in the circuit is equal to the reciprocal of the sum of the reciprocals of capacitance of all the individual capacitors.
We know that,
Where,
= Capacitive Reactance (in Ω)
f = frequency (in Hz)
C = Capacitance (in F)
Here given,
= ??
f = 60 Hz
C = 6 mF = F
Putting the values in the formula,
Therefore, the total capacitive reactance of the circuit is 442.10 Ω.
the cost of producing widgets decreased from 60 cents to 50 cents which
decreases at 18%
Answer:
The vale of x is 3/5.
Step-by-step explanation:
First you have to expand out :
Next you have to solve it by adding 6 to both sides :
Let expression = 0,
