Multiple choice don't ask! youfor ; ) calculate the area of the regular pentagon below: a regular pentagon with side length of 11.8 inches and dotted line from center to middle of side of 8.1 inches. 164.025 square inches 238.95 square inches 351.78 square inches 477.9 square inches

Each side of Pentagon is forming a triangle with third vertices being center of pentagon .

this way we get 5 triangles .

The line drawn from center to the mid point of side of pentagon is perpendicular line , that is height of triangle

ARea of such one triangle =

( 1/2)( side of pentagon )* height of the triangle )

(1/2)( 11.8 )( 8.1) = 47.79 square inch

Area of the pentagon = 5 times area of one such triangle =

5* 47.79 = 238.95

Answer : 238 .95 square inch

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:

answer:   2 multiplied by x =24
