List at least three shapes, other than pentagons, in the table. If the shape is a polygon, indicate whether the shape is regular

Sergio [31]

The number of times that the shape will map back onto itself as the shape rotates 360° about its center is 6.

<h3>What is the sum of all the exterior angles of a regular polygon?</h3>

For a regular polygon of any number of sides, the sum of its exterior angle is 360° (full angle).

Regular polygons have all sides the same and that apothem bisects the side in two parts, (provable by symmetry).

A regular polygon with n sides can map onto itself by n times

It will rotate 360°/n about its center every time and will map onto itself

Examples are in the attached table as well as the solution.

The number of times that the shape will map back onto itself as the shape rotates 360° about its center is 6.

Answer:

Step-by-step explanation:

$a(n) = a1 *(1.25)^{(n-1)}$

$a(1) = 5$

$a(2) = 5*(1.25)^{(2-1)}\\a(2) = 5*(1.25)^{1}\\a(2) = 5*(1.25)\\a(2) = 6.25$

$a(3) = 5 * (1.25)^{(3-1)} \\a(3) = 5 * (1.25)^{2}\\a(3) = 5 * 1.565\\a(3) = 7.813$

$a(4) = 5* (1.25)^{(4-1)}\\ a(4) = 5* (1.25)^{3}\\a(4) = 5* 1.953\\a(4) = 9.766$

$a(5) = 5 * (1.25)^{(5-1)}\\a(5) = 5 * (1.25)^{4}\\a(5) = 5 * 2.441\\a(5) = 12.207$

$a(6) = 5 * (1.25)^{5}\\a(6) = 5 * 3.052\\a(6) = 5 * 3.0517\\a(6) = 15.259$

$a(1) = 5$

$a(2) = 6.25$

$a(3) = 7.813$

$a(4) = 9.766$

$a(5)=12.207$

$a(6)=15.259$

Answer:

Approximately 439.6 square millimeters.

Step-by-step explanation:

The formula for the surface area of a cone is the following:

$A=\pi r^2+\pi r l$

Where, <em>r </em>is the radius and <em>l</em> is the slant height.

The radius is 7 and the slant height is 13. We also use 3.14 for π Thus:

$A=(3.14)(7)^2+(3.14)(7)(13)\\\text{Use a Calculator}\\A\approx 439.6$

Consider the following literal equation.

galina1969 [7]

We can solve this in many ways, let's try this one.

T∧2 = 4 pi∧2 * a∧3 / GM First we will multiply whole equation with variable( or parameter) M and get

M * T∧2 = 4 pi∧2 * a∧3 / G After that we will divide whole equation with variable ( or parameter ) T∧2 and get

M = 4 pi∧2 * a∧3 / G * T∧2

This is correct answer

Good luck!!!

A rectangular rug is 12.5 feet long and 10 feet wide. The rug needs to be reduced by a factor of One-fifth. What is the area of

aliya0001 [1]

The area of the reduced rug is 25 square feet

<h3>How to determine the area?</h3>

The dimensions are given as:

Length = 12.5 feet

Width = 10 feet

The area is calculated as:
Area = Length * Width

So, we have:

Area = 12.5 * 10

Evaluate

Area = 125

When reduced by one-fifth, we have:

Area =1/5 * 125

Evaluate

Area = 25

Hence, the area of the reduced rug is 25 square feet
