The current i in an electrical conductor varies inversely as the resistance r of the conductor. the current is 2 amperes when the resistance is 770 ohms. what is the current when the resistance is 808 ohms? round your answer to two decimal places if necessary.

The value of the current is 1.91 A.

Step-by-step explanation:

From the question, the current I in an electrical conductor varies inversely as the resistance R of the conductor.

The equation can be written as,

Here, K is the proportionality constant and R is the resistance.

It is given in the problem that the current is 2 amperes when the resistance is 770 ohms.

Calculate the value of K by using above expression.

Put I= 2 A and R= 770 ohm.

Calculate the value of the resistance when R= 808 ohms.

Put K= 1540 and R= 808 ohms.

Therefore, the value of the current is 1.91 A.

b.an increase in a causes b to decrease

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
