Follow the directions to convert the analog sound wave into a digital signal. the lines on the grid intersect at various points
dmitriy555 [2]

In this exercise we have to observe the axes of the graph to associate the values ​​of X with those of Y that correspond to 0, 5, 5, -3, -5, -3, 2, 0, 0, -1, -2, 1, 1, -1, -1, -2, 2, 3, -1.

<h3>How to calculate the Cartesian plane?</h3>

Just draw two lines: one of them vertical, starting from the point until it finds the x axis; another horizontal, starting from the point until it meets the y-axis.

Then plotting the value of X on the graph we find the following for each value of X to Y:

  • X= 0 ; Y= 0;
  • X= 1 ; Y= 5;
  • X= 2 ; Y= 5;
  • X= 3 ; Y= -3;
  • X= 4 ; Y= -5;
  • X= 5 ; Y= -3;
  • X= 6 ; Y= 2;
  • X= 7 ; Y= 0;
  • X= 8 ; Y= 0;
  • X= 9 ; Y= -1;
  • X= 10 ; Y= -2;
  • X= 11 ; Y= 1;
  • X= 12 ; Y= 1;
  • X= 13 ; Y= -1;
  • X= 14 ; Y= -1;
  • X= 15 ; Y= -2;
  • X= 16 ; Y= 2;
  • X= 17 ; Y= 3;
  • X= 18 ; Y= -1;

Write an expression for the area of the shaded region in its simplest form.
MatroZZZ [7]

Answer:

area = Iw

Explanation:

area = lw

where

l = length

w = width

Therefore,

The area of the shaded region  = area of the big rectangle - area of the small rectangle

Therefore,

area of the big rectangle = (x+10)(2x+5) = 2x² + 5x + 20x + 50 = 2x² + 25x + 50

area of the small rectangle = (x+1)(x+1) = x² + x + x + 1 = x² + 2x + 1

area of the shaded region = 2x² + 25x + 50 - ( x² + 2x + 1)

area of the shaded region =  2x² + 25x + 50 - x² - 2x - 1

area of the shaded region = x² - 23x - 49
