The equation solved for e gives e = rE/(R + r)

From the question, we are to solve for e. That is, we are to make e the subject of the given formula.

The given formula is

E/e = (R + r)/r

First cross multiply

E/e = (R + r)/r

e(R + r) = rE

Now, divide both sides of the equation by (R + r)

That is,

e(R + r)/ (R + r) = rE/ (R + r)

Thus,

e = rE/ (R + r)

Hence, the equation solved for e gives e = rE/(R + r)

Answer:

f(6) = - 10 and g(- 4) = 125

Step-by-step explanation:

substitute x = 6 into f(x) , that is

f(6) = - 2(6) + 2 = - 12 + 2 = - 10

substitute x = - 4 into g(x) , that is

g(- 4) = - 2(- 4)³ - 3 = - 2(- 64) - 3 = 128 - 3 = 125

Yes, it is true the cost of a pumpkin is proportional to the number bought.

We are given the table showing cost of each number of pumpkins. Now, let us analyze the table values;

1) When number of pumpkins is 1, then cost is $4. Thus;

Cost per pumpkin = 4/1 = $4 per pumpkin

2) When number of pumpkins is 2, then cost is $8. Thus;

Cost per pumpkin = 8/2 = $4 per pumpkin

3) When number of pumpkins is 3, then cost is $12. Thus;

Cost per pumpkin = 12/3 = $4 per pumpkin

4) When number of pumpkins is 4, then cost is $16. Thus;

Cost per pumpkin = 16/4 = $4 per pumpkin

In all these rates, we see that the cost rate for pumpkins remains the same. Thus, we can conclude that it is true the cost of a pumpkin is proportional to the number bought.

The length of the given rectangle is 4ft more than twice the width. The perimeter of the particular rectangle is 26ft. Length and width of the rectangle is [tex]10ft[/tex] and [tex]3ft[/tex]

As per the question statement, The length of the given rectangle is 4ft more than twice the width. The perimeter of the particular rectangle is 26ft.

We are supposed to find out dimensions of the rectangle.

Let length of the rectangle = l

Width of the rectangle = w

[tex]l = 4 + 2w[/tex]

Perimeter of rectangle = [tex]2(l+w)[/tex]

Above mentioned are the given conditions in the linear equation form.

Perimeter of rectangle = [tex]2(l+w)[/tex] = 26 ft.

[tex]l+w = \frac{26}{2}[/tex]

[tex]l+w =13[/tex]

substituting [tex]l = 4 + 2w[/tex]

[tex]4+2w+w=13\\4+3w=13\\3w=13-4=9\\w=\frac{9}{3}[/tex]

[tex]w=3[/tex]

Hence width is 3ft.

Now length,  [tex]l = 4 + 2w[/tex]

[tex]l=4+2*3\\l=4+6\\l=10[/tex]

And length is 10ft.

Straight  Line :

A straight line is an infinite-length line that does not have any curves on it. A straight line can be formed between two points also but both ends extend to infinity. A straight line is a figure formed when two points A (x1, y1) and B (x2, y2) are connected with the shortest distance between them, and the line ends are extended to infinity.

In the image shown below, a straight line between two points A and B is shown. A straight line AB is represented by: Vector AB

The lines are drawn in a slanting position or form some angle other than 0o, 90o, 180o, 270o, 360o with horizontal or vertical lines are called oblique or slanting lines.

y= - (x2+9-6x)+2

y= -x2-9+6x+2

There is an upper outlier and lower outlier that is 86.875 and -26.875.

An outlier is an observation that lies an abnormal distance from other values in a random sample from a population. In a sense, this definition leaves it up to the analyst (or a consensus process) to decide what will be considered abnormal. Before abnormal observations can be singled out, it is necessary to characterize normal observations.

There are 4 dollar bills are in a 0.28 inch stack.

Given that, the size of a dollar bill is width= 6.6 cm, length=15.6 cm and height= 0.109 mm= 0.109/10 =0.0109 cm.

The volume of the cuboid is the measure of the space occupied within a cuboid. The cuboid is a three-dimensional shape that has length, breadth, and height. If we have a rectangular sheet and we go on stacking such sheets, we will end up getting a shape that has some length, breadth, and height. The formula to find the volume of the cuboid = Length × Width × Height.

Now, the volume of a dollar bill=15.6 × 6.6 × 0.0109

=1.122264 cm³

Conversion of cm³ to cubic inches.

That is, 1.122264×0.0610237=0.06848≈0.07

Now, the number of dollars bills=0.28/0.07

=4

Therefore, there are 4 dollar bills are in a 0.28 inch stack.
