3 0

\large{\rm{\underline{\underline{Answer:}}}}

Angle AEB and Angle DEC are opposite angles which means they are equal in measure. Hence,

⇛ Angle AEB = Angle DEC

⇛ 9x + 8° = 3x + 42°

⇛ 9x - 3x = 42° - 8°

⇛ 6x = 34°

⇛ x = (34/6)°

<u>To </u><u>find</u><u>:</u> Angle DEC = 3(

34/6 °) + 42° = <u>5</u><u>9</u><u>°</u><u> </u><u>(</u><u>Ans)</u>

<h3>What is graph?</h3>

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The complete question is:

An Algebra II textbook manufacturer determines that its profit, in thousands of dollars, can be modeled by the following function, where x represents the number of Algebra II textbooks sold, in hundreds.

P(x) = 0.0013x^{4} +x -4.

Use a table of values to determine which graph represents the given situation. Number of Textbooks Sold (in hundreds) Number of Textbooks Sold (in hundreds) w. X. g 4

table for P(x) = 0.0013x^{4} +x -4.

x     P(x)

0     -0.8949

1       0.3328

2       1.8125

3       3.6848

By the table value we can say that the root is in (3,4)

The graph which shows is (W).
