Answer:
The voltage in exponential form would be .
The original voltage in the circuit is of a volt.
Step-by-step explanation:
Let x represent the original voltage.
We have been given that the voltage in an electrical circuit is multiplied by itself each time it is reduced. The voltage is 27/125 of a volt and it has been reduced 3 times.
The original voltage multiplied by itself for 3 times would be .
Now, we will equate with 27/125 as:
We know that 27 is cube of 3 and 125 is cube of 5, so we can represent our equation as:
Therefore, the voltage in exponential form would be
Now, we will take cube root of both sides to find original voltage in the circuit as:
Using property , we will get:
Therefore, the original voltage in the circuit is of a volt.
Answer:
Option C, 14/21=9/21 is the proportion.
Step-by-step explanation:
Given:
a.5/7 = 10/12
b.9/15 = 12/18
c.4/6 = 8/12
d.14/21 = 9/12
We have to find the proportions.
In proportion two ratios are equal, as it has an equality sign in between so both side must be of same ratio in its simplest form.
Let's work with option C
⇒
To find the simplest form we have to divide the numerator and denominator with same digit (or its factor).
Simplest form of =
,
=
Simplest form of =
Both sides in option C have equal ratios of 2/3.
So 4/6=8/12 is in proportion.
