The current I in an electrical conductor varies inversely as the resistance R of the conductor. The current is 1/5 ampere when the resistance is 8750 ohms. What is the current when the resistance is 17150 ohms?

0.102048 ampere

Step-by-step explanation:

I α k / R

Current = 1/5 ; R = 8750

What is the current when the resistance is 17150 ohms

First obtain the value of k :

I = k/R

I = 1/5 ampere = 0.2 A

0.2 = k / 8750

k = 1750

What is the current when the resistance is 17150 ohms

I = 1750 / 17150

I = 0.1020408

I = 0.102048 ampere

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
