a hot air balloon descends to the ground. the function $h(t)=210 - 15t$ can be used to describe the altitude of the balloon as it approaches the ground. which statement best describes the graph of the function that models the descent of the balloon?\nthe graph is discrete because there cannot be fractional values for time.\nthe graph is discrete because there cannot be negative values for altitude.\nthe graph is continuous because there can be fractional values for time.\nthe graph is continuous because there can be negative values for altitude.

Answer

Brief Explanations:

Time ($t$) in the context of the hot - air balloon's descent can take on fractional values (e.g., $t = 0.5$ hours). A function is continuous if the independent variable can take on any value within an interval. Since time can be any non - negative real number in this situation, the graph of the function $h(t)=210 - 15t$ is continuous.

Answer:

The graph is continuous because there can be fractional values for time.
