What is the area of this figure
Leviafan [203]
 First, you must observe the figure and realize that you have a parallelogram and a rectangle.
 Therefore, the total area will be the sum of the area of the parallelogram plus the area of the rectangle.
 Palelogram area:
  A1 = b * h
  We have then
  b = root ((- 4 - (- 10)) ^ 2+ (2-2) ^ 2) = 6
  h = root ((- 7 - (- 7)) ^ 2+ (3-2) ^ 2) = 1
  A1 = (6) * (1) = 6 units ^ 2
  Rectangle area
  A2 = L * W
  We have then:
   L = root ((1 - (- 2)) ^ 2 + (- 3 - (- 4)) ^ 2) = 3.16227766
   W = root ((- 4 - (- 2)) ^ 2+ (2 - (- 4)) ^ 2) = 6.32455532
   A2 = (3.16227766) * (6.32455532)
   A2 = 20 units ^ 2
   The total area is the sum of both ares:
   A = A1 + A2
   A = 6 + 20
   A = 26 units ^ 2
   Answer:
   the area of this figure
   A = 26 units ^ 2

Solve for x<br> -1/5(×-4)=-2<br><br> Enter your answer in the box.<br> ×=
Arisa [49]

Answer:

x = 14

Step-by-step explanation:

-1/5(x - 4) = -2

-1/5x + 4/5 = -2

-1/5x = -2 - 4/5

-1/5x = -10/5 - 4/5

-1/5x = - 14/5

x = -14/5 * - 5

x = 70/5

x = 14 <====

Exponential Function:
vovangra [49]

Answer:

See below

Step-by-step explanation:

<em>On the graphs we see transformations of exponential functions</em>

<h3>Graphic 1 = Horizontal shift </h3>
  • f(x) = 2ˣ is the parent function
  • g(x) = 2ˣ⁺³ indicates shift to the left by 3 units
  • h(x) = 2ˣ⁻¹ indicates the shift to the right by 1 unit
<h3>Graphic 2 =Vertical shift</h3>
  • p(x) = (1/3)ˣ is the parent function
  • r(x) = (1/3)ˣ⁺³ indicates shift up by 3 units
  • q(x) = (1/3)ˣ⁻² indicates the shift down by 2 units
