Question

on a windy autumn day, an acorn falls from a branch of a giant oak tree. the acorns height above the ground in feet can be modeled by the expression $80 - 16t^2$, where $t$ is the time in seconds after the acorn begins to fall. what does the quantity $16t^2$ represent in the expression? the time in seconds it takes for the acorn to fall $t$ feet the time in seconds it takes for the acorn to reach a height of $t$ feet the distance in feet the acorn has fallen after $t$ seconds the height in feet of the acorn after $t$ seconds

Explanation:

Step1: Analizar la expresión \( 80 - 16t^2 \)

La expresión \( 80 - 16t^2 \) modela la altura del bellota sobre el suelo después de \( t \) segundos. Aquí, \( 80 \) representa la altura inicial del bellota sobre el suelo (cuando \( t = 0 \), la altura es \( 80 \) pies).

Step2: Interpretar \( 16t^2 \)

Como la altura total inicial es \( 80 \) y la altura después de \( t \) segundos es \( 80 - 16t^2 \), entonces \( 16t^2 \) debe representar la distancia que el bellota ha caído después de \( t \) segundos. Esto se debe a que la altura restante es la inicial menos la distancia caída.

Answer:

the distance in feet the acorn has fallen after \( t \) seconds
