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

e units are volts, amperes, and ohms. Assume that the voltage is constant with V = 20 V. Calculate the average rate of change of I with respect to R for the interval from R = 6 to R = 6.1 . (Use decimal notation. Give your answer to three decimal places.)

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.

This is because simplifying the equation before solving it will lead you to the answer at a much faster rate. For example, in the given equation, the long way would be to distribute 2 to (x+3). Then, you transpose them and combine like terms. Until you get to x + 3 = 8. But if you simplify it first, you will see that it is straightforward. It will lead you to the answer right away which is x + 3 = 8. It saves you from the hassle of doing more algebra :)

A chicken farmer also has cows for a total of 30 animals, and the animals have 66 legs in all. How many chickens does the farmer
hammer [34]

Answer:

27 chickens

Step-by-step explanation:

A chicken farmer also has cows for a total of 30 animals

Both animals have a total of 66 legs

Let a represent the number of chicken

Let b represent the number of cows

a + b= 30........equation 1

Since a chicken has only two legs and a cow has four leg then, the expression can be represented as

2a + 4b= 66........equation 2

From equation 1

a + b= 30

a = 30-b

Substitute 30-b for a in equation 2

2a + 4b= 66

2(30-b) + 4b= 66

60 - 2b + 4b= 66

60 + 2b= 66

2b= 66-60

2b= 6

b= 6/2

b= 3

Substitute 3 for b in equation 1

a + b = 30

a + 3=30

a= 30-3

a= 27

Hence the farmer has 27 chickens
