According to Ohm’s Law, the voltage V , current I , and resistance R in a circuit are related by the equation V = I R , where th
Helen [10]

Answer:

The average rate of change as follows of I is -0.185.

Step-by-step explanation:

The relation between voltage V, current I, and resistance R in a circuit, according to the Ohm's law is:

V = IR

It is provided that:

<em>V</em> = 20 V

The interval between which R varies is, R = 8 to R = 8.1.

Compute the value of I as follows:

V=IR\Rightarrow I=\frac{I}{R}\Rightarrow I=\frac{20}{R}

Compute the average rate of change as follows of I as follows:

\frac{\delta I}{\delta R}=\frac{(I\times8.1)-(I\times8)}{8.1-8}

    =\frac{1}{0.1}[\frac{12}{8.1}-\frac{12}{8}]

    =\frac{12}{0.1}[\frac{8-8.1}{64.8}]

    =-0.1852

Thus, the average rate of change as follows of I is -0.185.

1/3 (4+2)=-2/5(x-9) and x=4
VladimirAG [237]
So it will be
1/3(6)=-2/5(-5)
then will remove minus
1/3*6=2/5*5
then cancle 3 and 6 will be 2 and remove 5
So it become like this 2=2 it is True

Vlad [161]

Answer:

33.33%

Step-by-step explanation:

Given :

Breakup percentage = 15

New relationship percentage = 30

To obtain the steady state percentage of residents who are uninvolved, we could relate the scenario to the natural unemployment rate relation : seperation rate ÷ (seperation rate * finding rate)

Hence, we could use the Relation as this ;

Breakup percentage ÷ (Breakup percentage + new relationship rate)

15% ÷ (15% + 30%)

0.15 ÷ (0.15 + 0.30)

0.15 ÷ 0.45

= 0.33333

= 33.33%

An element with mass 330 grams decays by 25.5% per minute. How much of the element is remaining after 5 minutes, to the nearest
babymother [125]
Equation: 330-.255(5)=X. Multiply: .255(5)=1.275, 330-1.275=X. Subtract: 330-1.275=328.725 or 328.73 :)

What percent of 40 = 32, I know....I should know this!
Hunter-Best [27]
To find that divide 32 by 40  and multiply by 100 so
32/40 *100% =80%
Therefore 32 is 80 percent of 40
