Mathematics
1 answer:
Strike441 [17]3 years ago

Responder:

15m

Explicación paso a paso:

Dada la expresión de la altura de la pelota lanzada modelada por la ecuación;

h (x) = -5x² + 10x + 15

El momento en que se arrojó la piedra es cero, es decir, x = 0 segundos

Sustituya x = 0 en la ecuación y encuentre h (x) como se muestra;

h (x) = -5x² + 10x + 15

h (0) = -5 (0) ² + 10 (0) +15

h (0) = 0 + 0 + 15

h (0) = 15 m

De ahí que la altura de la piedra cuando la arrojes sea de 15 m
