How can I do this exercice (n+1)!/(n+2)! ?

Answers

Answer 1

Answer: (n+1)! is equal to (n+1)*n*(n-1)*(n-2)...*3*2*1. Basically, it multiplies together every positive integer that is at most n+1. This is the definition of the !, or the factorial function.

(n+2)! is equal to (n+2)*(n+1)*n*(n-1)*(n-2)...*3*2*1, using the same definition. This thus is equal to (n+1)!*(n+2), so we have:

(n+1)!/(n+1)!(n+2), or:

1/(n+2)

This is our final simplification.

A triangle with base on an extended line. Two angle measures are given. Top interior angle is twenty-eight degrees. Lower left exterior angle is seventy-one degrees. Lower right interior angle is labeled x degrees.

Answers

The correct answer for the question that is being presented above is this one: "The lower right interior angle is 43°"

Interior angle of a triangle and its corresponding exterior angle must have a sum of 180° when its line is extended.

Top interior angle is 28°
Lower left exterior angle is 71°
Lower right interior angle is x°

Get the left interior angle.
Exterior angle + Interior angle = 180°
71° + Interior angle = 180°
Interior Angle = 180° - 71°
Interior Angle = 109°

Top Interior angle + Left Interior Angle + Right Interior angle = 180°
28° + 109° + x° = 180°
x = 180° - 28° - 109°
x = 180° - 137°
x = 43°

The lower right interior angle is 43°

B. 1,234 in3

C. 4,628 in3

D. 3,610 in3

The volume of wood used for a wooden gate is 1234 in³

B. 1234 in³

How to find the volume of wood

The volume of wood is solved by the formula

surface area * thickness

The surface is of two shapes:

Semi circle

Rectangle

The length of the rectangle is the diameter of the circle and the length is

= 6 * x = 6 * 6 = 36 inches

Area of semi circle

= 0.5 * π * D² / 4

= 0.5 * π * 36² / 4

= 508.94 square inch

Area of rectangle

= 36 * 3

= 108 square inch

Total surface area = 508.94 square inch + 108 square inch

Total surface area = 616.94 square inch

Volume of wood = Total surface area * y

Volume of wood = 616.94 * 2

Volume of wood = 1233.88

Volume of wood = 1234 in³
