Step-by-step explanation:

[tex]1.2 X 100=120.\\[/tex]

Answer:

The mass of an average grain of rock salt is 1.2 x 10^-2. In part A, you multiplied 10^-2 by 10^-2 to get 10^-4. So, multiply the first factor, 1.2 , by 10^2, or 100.

The first factor will then be 1.2 x 100 = 120.

Answer:

Step-by-step explanation:

The first line is:

It has undefined rate of change

The second line is:

It has rate of change of zero (no change in y-value for any x-value)

Answer:

Here, the rate of change is not defined.

Here, the rate of change is zero .i.e., y is independent of x.

Therefore, 2nd graph has a rate of change of zero.

Answer:

The area is 28 cm squared.

The perimeter is 22 cm.

Step-by-step explanation:

To find the area, multiply one side length by the other.

7x4 = 28 cm^2

To find perimeter add the four sides of the rectangle.

7 + 7 + 4 + 4 = 22 cm

Answer:

Step-by-step explanation:

let x be the common ratio / or scale factor

the sides of the triangle are

5x, 12x and 13x

sum of the sides defines perimeter

that is

5x + 12x + 13x = 15

30x = 15

x = 15/30

x = 0.5

The sides of the triangle are 0.5(5) = 2.5

0.5(12)=6

0.5(13) = 6.5

2.5, 6, 6.5 all in inches

Answer: part 1

1. You need a Source of electric power (battery or generator), a load to absorb the power (lamp, motor, heating coil) and wiring to connect the load to the power source!

2. they both give off electricity energy, and they are different because they dont release the same amount of energy

3. Current will increase

Explanation:

In Ohm's law the equation for current is current = voltage / resistance.

In order to explain how current is effected when resistance decreases while voltage stays the same, lets represents the situations with some possible inputs.

Let's compare 3 different closed circuits all with a voltage of 10V.

In circuit 1, the resistance is 5 ohm.

In circuit 2, the resistance is 2 ohms.

In circuit 3, the resistance is 1 ohms.

The current of:

Circuit 1 = Voltage / Resistance = 10 V / 5 ohms = 2 Amps

Circuit 2 = Voltage / Resistance = 10V / 2 ohms = 5 Amps

Circuit 3 = Voltage / Resistance = 10V / 1ohm = 10 Amps

As you can see in this representation, as the resistance in a circuit increases while the voltage is constant, the total current is increased.

4. The resistance of a conductor is the ratio of the voltage

between its ends to the current through it.

If the voltage between the ends of a light bulb's filament

increases but the filament's resistance remains constant,

then the current through it increases by the same factor

as the voltage increase. The effect is to cause the light

to emit more light and heat ... both increase proportional

to the square of the voltage ... and possibly to "burn out".

Part 2

1. it's a circuit wherein all the elements are in parallel and a resistance is fitted in series across which a voltmeter is connected to measure potential drop acrossR so as to find the current across the load that is bulb which connected to in series with the resistor

2. A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.

3. The switch simply opens (off) or closes (on) the connection between the two terminals on the switch. When the switch is on, current flows along the black wire through the switch to the light, and then returns to ground through the white wire to complete the circuit.

4. the current runs through the motherboard and into the smaller components or the small internal wiring

5. A battery is made up of three parts. The Cathode (positive end +) , the Anode (negative end -) and the electrolyte. The electrolyte allows electrical charges to travel between the cathode and anode. This chemical reactions creates the flow of electricity supplying the electrical voltage potential to power a circuit.

Typical materials of a battery are as follows

- Anode most often is made of zinc

- Manganese dioxide acting as Cathode.

- the electrolyte between and inside contains ions

Hope this help

To make a complete circuit, you need three basic components: a power source, such as a battery, a load, such as a light bulb, and a conductor, such as a wire, to connect the two.

The electric circuit is a closed-loop or path that forms a network of electrical components, where electrons can flow.

The power source provides the electrical energy that flows through the conductor to the load, which converts electrical energy into other forms of energy, such as light or heat.

A parallel circuit is a circuit in which the components are connected across each other so that the current is divided among them.

One way that series and parallel circuits are alike is that they both require a complete path for the current to flow.

One way that they are different is that the total resistance in a series circuit is equal to the sum of the individual resistances, whereas, in a parallel circuit, the total resistance is less than the smallest individual resistance.

If the amount of resistance decreases and the voltage stays the same, the current will increase.

This is because a lower resistance allows more current to flow for a given voltage.

If the voltage increases but the resistance stays the same, the current will also increase.

This is because according to Ohm's law, the current is directly proportional to the voltage and inversely proportional to the resistance.

Therefore, if the voltage increases, the current must also increase to maintain the same level of resistance. If the current exceeds the rating of the light bulb, it may burn out or even explode.

When we divide a number by the power of ten the decimal point shifts towards left of that number. Mathematically for example,

[tex] \frac{6}{10} = 0.6 \\ \frac{54}{10} = 5.4 \\ \frac{234}{10} = 23.4 \\ \frac{132}{ {(10)}^{2}}= \frac{132}{100} = 1.32 \\ \frac{2345}{ {(10)}^{3} } = \frac{2345}{1000} = 2.345 [/tex]

Note: your g(x) function is a little bit unclear. Thus, I am assuming that

g(x) = 2x-1

Anyway, the procedure remains the same. It would anyways clear your concpet.

Answer:

(f+g)(x) = 5x³ + 2x - 3

Step-by-step explanation:

Given

f(x) = 5x³ - 2

g(x) = 2x - 1

To determine

(f+g)(x) = ?

Using the formula expression

(f+g)(x) = f(x) + g(x)

           = 5x³ - 2 + 2x - 1

           =  5x³ + 2x - 3

Therefore, we conclude that:

(f+g)(x) = 5x³ + 2x - 3

Answer: 12 sections of 1/16 acre

Step-by-step explanation:

We want to find how many sections of 1/16 acre we can have in a total area of 3/4 acre.

This is equal to the quotient between 3/4 and 1/16

Remember that if we have two rational numbers (a/b) and (c/d) the quotient can be writen as:

(a/b)/(c/d) = (a/b)*(d/c) = (a*d)/(b*c)

The quotient we want to solve is:

(3/4)/(1/16) = (3/4)*(16/1) = (3*16)/4 = 12

Then you can have 12 sections of 1/16 acre

Answer:

Answer:

14.

Step-by-step explanation:

3x + 7y = 12

x - y = 1           Multiply this by -3:

-3x + 3y = -3     Add this to equation 1:

0 + 10y = 9

so y = 9/10 = 0.9.

x - 0.9 = 1

x = 1.9.

So 5x + 5y = 5*1.9 + 5*0.9

= 14.

Answer:

16 boxes

Step-by-step explanation:

160+50x=1000

Solve for the x and you'll get 16.8. Now, because you can't have a fraction of a box, and you can't go over the limit, the answer is 16 boxes.

(How to solve for x:

Get x by itself by subtracting 160 to both sides.

50x=1000-160

50x=840

Divide both sides by 50.

x=16.8)

Answer:

Since the calculated value of Z= -0.01871 does not lie in the critical region

Z ≥ Z∝ =± 1.28 we conclude that the null hypothesis is true and there is not sufficient evidence to support the claim that the bags are under filled.

Step-by-step explanation:

We formulate hypotheses as

H0: u < 433.0   against  the claim  Ha: u ≥ 433.0  ( one sided)

The significance level ∝= 0.1

Since the sample size n= 40 is greater then 30 z test is used.

Z = X`- u/ S/ √n

Z= 431.0- 433/ 676/√40

z= -2/106.8859

Z= -0.01871

The critical region is Z ≥ Z∝ =± 1.28 for one tailed test at alpha= 0.1

Since the calculated value of Z does not lie in the critical region we conclude that the null hypothesis is true and there is not sufficient evidence to support that the bags are under filled.
