The geometric series to give a series for 1 1+x Then differentiate your series to give a formula for + ((1+x)-4)= ... (1 +x)2 1 dx is (1+x)^(-4) = -4/(1+x) + 4/(1+x)^3.
To obtain a series representation for 1/(1+x), we can use the geometric series formula:
1/(1+x) = 1 - x + x^2 - x^3 + ...
This series converges when |x| < 1, so we can use it to find a series for 1/(1+x)^2 by differentiating the terms of the series:
d/dx (1/(1+x)) = d/dx (1 - x + x^2 - x^3 + ...) = -1 + 2x - 3x^2 + ...
Multiplying both sides by 1/(1+x)^2, we get:
d/dx (1/(1+x)^2) = -1/(1+x)^2 + 2/(1+x)^3 - 3/(1+x)^4 + ...
To obtain a formula for (1+x)^(-4), we can use the power rule for differentiation:
d/dx (1+x)^(-4) = -4(1+x)^(-5)
Multiplying both sides by (1+x)^4, we get:
d/dx [(1+x)^(-4) * (1+x)^4] = d/dx (1+x)^0 = 0
Using the product rule and the chain rule, we can expand the left-hand side of the equation:
-4(1+x)^(-5) * (1+x)^4 + (1+x)^(-4) * 4(1+x)^3 = 0
Simplifying the expression, we get:
-4/(1+x) + 4/(1+x)^3 = (1+x)^(-4)
Therefore, (1+x)^(-4) = -4/(1+x) + 4/(1+x)^3.

Can someone please help me with this similar area question? I have the answer but I’m not sure how to get to it. Will make brainliest!
Step-by-step explanation:
well there is a very simple point that you have mistaken tho:
484cm², 25cm²
Areas are defined in square cm but the radius is in cm
so:
[tex] \sqrt{ \frac{484 {cm}^{2} }{25 {cm}^{2} } } = \frac{7.92}{r} = = = > 4.4 = \frac{7.92cm}{x} = = > x = \frac{7.92cm}{4.4} = x = 1.8cm[/tex]
and there you go
if the length of a rectangle is decreased by 2cm and the width is increased by 6 cm the result will be a square the area of this square will be 64 cm^2 greater than the area of a rectangle find the area
The area of the rectangle is 105 square cm
How to determine the rectangle area?Represent the dimensions of the rectangle with x and y
So, the length of the square would be:
Length = x - 2
Width = y + 6
The areas are then calculated as:
Rectangle = xy
Square = (x -2)(y + 6)
The relationship between the areas is:
(x -2)(y + 6) = 64 + xy
Expand
xy + 6x - 2y - 12 = 64 + xy
This gives
6x - 2y - 12 = 64
Add 12 to both sides
6x - 2y= 76
Divide through by 2
3x - y = 38
By trial by error, we have:
x = 15 and y = 7
The rectangle area is then calculated as:
Rectangle = xy
This gives
Rectangle = 15 * 7
Evaluate
Rectangle = 105
Hence, the area of the rectangle is 105 square cm

The sunshade on one set of equipment has a square base of 120 cm and a height of 50 cm. The
sunshades are open-bottomed square based pyramids. This means that the base is not included.
a. Determine the total surface area, in m², of the sunshade.
The total surface area, in m², of the sunshade is 0.4344 m²
How to calculate surface area of a squared pyramid ?A pyramid can have a squared base, rectangular base or other polygons. The formula we can to find the total surface area of a squared pyramid is
Surface Area = P x l/2
Where
P = base parameterl = slant heightGiven that a sunshade on one set of equipment has a square base of 120 cm and a height of 50 cm. That means that the length L of the base will be 120 cm and half of it will be 60 cm
To find the slant height l, we will use Pythagoras theorem.
[tex]l^{2}[/tex] = 60² + 50²
[tex]l^{2}[/tex] = 3600 + 2500
[tex]l^{2}[/tex] = 6100
l = √6100
l = 78.1 cm
convert it to meter
l = 78.1/100
l = 0.781 m
The perimeter P of the base = 4 x 120/100 = 4.80 m
The Surface Area = P x l/2
Substitute all the necessary parameters into the formula
Surface Area = 4.80 x 0.781/2
Surface Area = 1.8744 m²
If the sunshades are open-bottomed square based pyramids, this means that the base is not included. That is, the area of the base should be taken away from the answer above.
Area of the base = 120/100 x 120/100 = 1.44 m²
The total surface area, in m², of the sunshade will 1.8744 - 1.44
The total surface = 0.4344 m²
Therefore, the total surface area, in m², of the sunshade is 0.4344 m²

(x - 5)(x - 1) = x² - 6x + 5
(x - 4)(x - 10) = x² - 14x + 40

Step-by-step explanation:
Use FOIL.

F - first: x × x = x²
O - outer: -2 × x = -2x
I - inner: 6 × x = 6x
L - last: 6 × -2 = -12

Step 1: Place the graph paper in landscape orientation. Measure from the top left hand corner 6 inches right and 5 inches down. This will be your starting point for
your diagram.
Step 2: Using a ruler and index card/protractor create an isosceles Right triangle. Drawing the triangles legs 1 inch straight up from the starting point and 1 inch to the
right of the starting point. Connect the endpoints of the two segments to create your right isosceles triangle.
Step 3: On a separate piece of paper, use the Pythagorean Theorem to calculate the length of the hypotenuse. You only need to do this for the first 8 if you discover a
pattern.
Step 4: Using your original Right triangle, add another leg measuring 1 inch and right angle to the hypotenuse of your original Right triangle. Connect the endpoints
to form a new hypotenuse for your new Right triangle.
Step 5: Show the calculations to find the length of the new hypotenuse.
Step 6: Continue to repeat this process of connecting and drawing new triangles with a side length of 1 inch, using the previous hypotenuse as the other side. Draw
triangles until you are able to measure the square root of 17. You must show all calculations (Step 3) on a separate piece of paper.
The right triangle whose hypotenuse is the square root of 17 has legs of 1 inch and 4 inches
How to determine the hypotenuse?Step 1 and 2: Create an isosceles right triangle
This is represented by the attached figure in (see figure 1 for this triangle)
The legs of this triangle have a length of 1 inch
Step 3: The hypotenuse
This is calculated using the following Pythagoras theorem
[tex]h^2 = 1^2 + 1^2[/tex]
This gives
[tex]h = \sqrt 2[/tex]
Step 4: Create another isosceles right triangle
This is represented by the attached figure in (see figure 2 for this triangle)
The legs of this triangle are 1 inch and 2 inches, respectively
This hypotenuse is calculated by:
[tex]h^2 = 2^2 + 1^2[/tex]
This gives
[tex]h = \sqrt 5[/tex]
Step 5: Create another isosceles right triangle
This is represented by the attached figure in (see figure 3 for this triangle)
The legs of this triangle are 1 inch and 3 inches, respectively
This hypotenuse is calculated by:
[tex]h^2 = 3^2 + 1^2[/tex]
This gives
[tex]h = \sqrt {10[/tex]
Step 6: Create another isosceles right triangle
This is represented by the attached figure in (see figure 4 for this triangle)
The legs of this triangle are 1 inch and 4 inches, respectively
This hypotenuse is calculated by:
[tex]h^2 = 4^2 + 1^2[/tex]
