15 bulbs are red.

Step-by-step explanation: Because 75 is 3 times as big as 25 so every 1 green light bulb 3 red light bulbs will be deflective.

The graph that correctly represents f(x) = –2(x + 4)² is graph (B).

So, graph of: f(x) = –2(x + 4)²

Then,

Now, plot (-2x - 8)² on the graph.

(Refer to the graph attached below)

Therefore, the graph that correctly represents f(x) = –2(x + 4)² is graph (B).

Part 1: Answer the following questions (20 points)

1. Name and describe the components needed to make a complete circuit.

. battery

. connecting wire

. resister  

. voltmeter

. ammeter

2. Compare and contrast a series and parallel circuit. Give at least one way that they are alike and one way that they are different.

They both give off electricity energy, and they are different because they don't release the same amount of energy

3. Ohm's law is represented by the equation I = V/R. Explain how the current would change if the amount of resistance decreased and the voltage stayed the same.

In accordance with the law, if r became smaller, and V stayed the same, the current would increase. The increases would be inversely proportional to the resistance, if the resistance was halved, the current would double.

4. Define resistance and describe what would happen to a light bulb if the voltage increased but the resistance stayed the same. The resistance of a conductor is the ratio of the voltage

between its ends to the current through it

The midpoint is at 20

Step-by-step explanation:

The midpoint of a segment

Given a segment in the number line with endpoints A(xa) and B(xb).

The midpoint coordinate is calculated as follows:

[tex]\displaystyle xm=\frac{xa+xb}{2}[/tex]

We are given the coordinates xa=10 and xb=30, thus the coordinate xm of the midpoint M is at:

[tex]\displaystyle xm=\frac{10+30}{2}[/tex]

[tex]\displaystyle xm=\frac{40}{2}[/tex]

xm = 20

The midpoint is at 20

Step-by-step explanation:

You always multiply when doing area.

Consider we need to find the equation of the parabola.

Given:

Parabola with focus (2, 1) and directrix x=-8.

To find:

The equation of the parabola.

Solution:

We have directrix x=-8. so, it is a horizontal parabola.

The equation of a horizontal parabola is

[tex](y-k)^2=4p(x-h)[/tex]           ...(i)

where, (h,k) is center, (h+p,k) is focus and x=h-p is directrix.

On comparing focus, we get

[tex](h+p,k)=(2,1)[/tex]

[tex]h+p=2[/tex]          ...(ii)

[tex]k=1[/tex]

On comparing directrix, we get

[tex]h-p=-8[/tex]         ...(iii)

Adding (ii) and (iii), we get

[tex]2h=2+(-8)[/tex]

[tex]2h=-6[/tex]

Divide both sides by 2.

[tex]h=-3[/tex]

Putting h=-3 in (ii), we get

[tex]-3+p=2[/tex]

[tex]p=2+3[/tex]

[tex]p=5[/tex]

Putting h=-3, k=1 and p=5 in (i), we get

[tex](y-1)^2=4(5)(x-(-3))[/tex]

[tex](y-1)^2=20(x+3)[/tex]

Therefore, the equation of the parabola is [tex](y-1)^2=20(x+3)[/tex].

Find slope-intercept form

Answer:

337.35 mi/h^2

Step-by-step explanation:

Given the equation;

v= u +at

v= final velocity = 51 mi/h

u= initial velocity = 23 mi/h

t = time = 5 mins or 0.083 hours

a = acceleration, the unknown

51 = 23 + 0.083a

51 - 23 = 0.083a

a= 51 - 23/0.083

a= 337.35 mi/h^2

The distance between 7 and zero on a number line

Step-by-step explanation:

Answer:

the first one

Step-by-step explanation:

0 to 7 on a number line is 7

Answer and Step-by-step explanation: In math, a graph, function or equation can be alterated - by shifting, reflecting, stretching or compressing - without losing its original shape. For example, a quadratic function maintains its parabolic shape when shifted.

When an equation is transformed vertically, it means its y-axis is changed. When it is horizontally, its x-axis is modified.

For equation [tex]y=x^{3}[/tex]:

This means the exponential equation will be multiplied by a constant, in this case 3. Then, the new equation is

[tex]y=3x^{3}[/tex]

When an equation is shifted, it's added a constant to it. As it is horizontal, it means it is added to the x and because it is to the right, it is a plus symbol:

[tex]y=x^{3+4}[/tex]

Vertical shift means the equation is 3 units "below" the original equation, so:

[tex]y=x^{3}-3[/tex]

Option "B" is correct answer

Step-by-step explanation:

Given:

Wal-Mart Stores, Inc = 677,500

General Motors Corp = 646,200

Pepsi Co, Inc. = 485,100

Ford Motor = 372,900

Sears Roebuck & Company = 336,100

Find:

Chart

Computation:

Total = 677,500 + 646,200 + 485,100 + 372,900 + 336,100

Total = 2,517,800

Percent Wal-Mart Stores, Inc = 677,500 / 2,517,800 = 26.90 %

Percent General Motors Corp = 646,200 / 2,517,800 = 25.66 %

Percent Pepsi Co, Inc. = 485,100 / 2,517,800 = 19.26 %

Percent Ford Motor = 372,900 / 2,517,800 = 14.81 %

Percent Sears Roebuck & Company = 336,100 / 2,517,800 = 13.34 %

So, Option "B" is correct answer.

i personally think it is B i might be wrong tho

Step-by-step explanation:

Answer:

Step-by-step explanation:

since the line crosses the y axis at -4  we know that b in the slope intercept form is -4 . now we just need the slope..  and slope is rise over run  or y/x... soooo   .....

looking at the graph I see that the point (-1,4) and (0,-4) look like they are points on the graph..  

soooo....

the rise is -8 when the run is 1 or  -8/1  or just -8

use the slope intercept form  y = mx + b

y= -8x + (-4)

y = -8x -4    :)

c = 27/40
