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
The complement is equal to 90 so the complement to 70 is 20. the supplement adds to 180 so the supplement to 70 is 110. if you are talking about x... it’s an isosceles triangle so the base angles are the same and the angles in a triangle add to 180 so 180-(70+70)=40 so x=40 so the complements is 50 and the supplement is 150
Answer:
(B)
Step-by-step explanation:
Volume of fluid in the tank =1000 gallons
Initial Amount of Salt in the tank, A(0)= 30 pounds
Incoming brine solution of concentration 2 pounds of salt per gallon is pumped in at a rate of 4 gallons per minute.
Rate In=(concentration of salt in inflow)(input rate of brine)
The resulting mixture is pumped out at the same rate, therefore:
Rate Out =(concentration of salt in outflow)(output rate of brine)
Therefore:
The rate of change of amount of salt in the tank,
Answer:
C) x=y

Answer:
Even Function
Solution:
For an even function:
f(x) = f(-x)
For an odd function:
f(x) = -f(x)
Since f(-x) = f(x), the given function is an even function.
