Write a quadratic equation in standard form that has the following solutions: x = 4/3 and x = - 2/5

Answers

Answer:

15x^2 - 14x - 8 = 0.

Step-by-step explanation:

(x  - 4/3)(x + 2/5) = 0

Converted to integer values by multiplying the first bracket by 3 and the second by 5:

(3x - 4)(5x + 2) = 0

Expanding the brackets:

15x^2 + 6x - 20x - 8 = 0

15x^2 - 14x - 8 = 0.

Elisa y su sombra forman un ángulo recto . La sombra anide 1,2 m y el ángulo con el que se ve la parte superior de su cabeza desde el extremo de la sombra mide 54° 50° . Calcular la altura de Elisa

Answers

Answer:

h = 1.65 m

Step-by-step explanation:

Me parece que el problema está mal formulado por lo siguiente:

El angulo al que se refiere el problema es 54°  o es 50°  o es 54°,50´

Como resolver el problema en cualquier caso.

Si Elisa y su sombra forman un angulo recto, entonces Elisa, su sombra y la distancia entre la cabeza de Eliza y el final de su sombra forman un triangulo rectangulo. Para el cual entonces solo es necesario buscar la tangente del angulo ( cateto opuesto sobre cateto adyacente) como conocemos el cateto adyacente ( la sombra de Elisa ) calculamos la altura de Elisa (h).

Asumamos que el angulo es de 54°  entonces

tang 54° = 1.3763

tang 54° = 1.3763  = h/1.2

h = 1,3763*1,2  m

h = 1.65 m

De igual manera se procedería si el angulo es de 50° ( en este caso la    tang 50° = 1.1917
