which car can travel farther on 1 gallon of gas if blue car travels 18 2/5 miles using 0.8 gallons of gas and red car travels 17
Black_prince [1.1K]

Divide the miles by the gallons used for each car to find the miles per gallon, then compare them:

Blue car: 18 2/5 miles / 0.8 gallons = 23 miles per gallon.

Red car: 17 2/5 miles / 0.7 gallons = 24.86 miles per gallon.

The red car can travel farther on 1 gallon of gas.

El ingreso de una empresa de construcción de obras civiles se estima a través del tiempo de acuerdo con la siguiente función I(t
brilliants [131]

Usando conceptos de funciones cuadráticas, se encuentra que:

  • El máximo ingreso será alcanzado en 6 años.
  • El máximo ingreso será de 800 miles de soles.

La función que estimate el tiempo es dada por:

I(t) = -64 + 288t - 24t^2

Que es una función cuadrática con coeficientes a = -24, b = 288, c = -64.

El año en qué se alcanzará el máximo ingreso es el <u>valor de t de el vertice</u>, o sea:

t_V = -\frac{b}{2a} = -\frac{288}{2(-24)} = \frac{288}{48} = 6

El máximo ingreso será alcanzado en 6 años.

El valor del máximo ingreso es el valor de <u>I de el vertice</u>, o sea:

I_v = -\frac{\Delta}{4a} = -\frac{b^2 - 4ac}{4a}

Entonces:

I_v = -\frac{288^2 - 4(-24)(-64)}{4(-24)} = 800

El máximo ingreso será de 800 miles de soles.
