La función que a cada número le asocia su mitad es: f(x)= x/2
Explicación:
La mitad de una cantidad consiste en dividir el total en dos partes iguales, por lo tanto, la función debe representar una división entre el total y 2. Sea x el total, la función sería:
f(x)= x/2
Ejemplos:
La mitad de 20: f(20)= 20/2 = 10
La mitad de 8: f(8)= 8/2 = 4
La mitad de 100: f(100)= 100/2 = 50
La mitad de 2354: f(2354)= 2354/2 =1177

Answer:
Area of the shaded region = 23.33 in²
Step-by-step explanation:
Area of a sector = 
Where θ = Central angle subtended by an arc
r = radius of the circle
Area of the sector BCD = 
= 52.36 in²
Area of equilateral triangle BCD = 
= 
=
in²
= 43.30 in²
Area of the shaded portion in ΔBCD = 52.36 - 43.3
= 9.06 in²
Area of sector CAD = 
= 39.27 in²
Area of right triangle CAD = 
= 
=
= 25 in²
Area of the shaded part in the ΔACD = 39.27 - 25
= 14.27 in²
Area of the shaded part of the figure = 9.06 + 14.27
= 23.33 in²
Step-by-step explanation:
A = 1/2h(b1 + b2)
2A = h(b1 + b2)
h(b1 + b2) = 2A
h = 2A/(b1 + b2)
