Answer:

22.2 ft²

Step-by-step explanation:

The area (A) of a sector is calculated as

A = area of circle × fraction of circle

  = πr² × \frac{50}{360}

  = π × 7.13² × \frac{5}{36}

  = \frac{7.13^2(5)\pi }{36} ≈ 22.2 ft² ( nearest tenth )

19. 4/6 or 2/3 (lowest term) or 2:3 in ratio
20. 2/3 or 2:3 in ratio
21. 5/12 or 5:12 in ratio
22. 14
    To get geometric mean, multiply the numbers then get the square root of the product (if there are two numbers), cube root (if there are three numbers), and so on. In this case, 7*28 = 196; √196 = 14
23. 10 ft : 2.5 ft.
    Convert the values so that it will be similar. In this case, 30 inches is converted to ft.
24. 24 is the Perimeter of ABCDE.
    ABCDE and FGHJK are similar shapes. Similar shapes have proportional measurements.

Now compute for the sides of ABCDE.
AB = 4; BC = ?; CD = ?; DE = ?; EA = ?
AB + BC + CD + DE + EA
4 + 4 + 5 + 6 + 5 = 24

Find BC:
AB/BC = FG/GH
   4/BC = 8/8 
    8BC = 32
      BC = 4

Find CD:
BC/CD = GH/HJ
   4/CD = 8/10
    8CD = 40
      CD = 5

Find DE:
CD/DE = HJ/JK
   5/DE = 10/12
  10DE = 60
       DE = 6

Find EA
DE/EA = JK/KF
   6/EA = 12/10
  12EA = 60
      EA = 5

Which is the dependent variable in 4x^2-5/6x-9=y if y=f(x)
olga55 [171]

Answer:

  y

Step-by-step explanation:

The expression

  y = f(x)

tells you that y is the dependent variable, and that it depends on x, the independent variable. The <em>independent</em> variable is always the function argument. Any variable that depends on that is the <em>dependent</em> variable.
