Ahot 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?

a) the graph is discrete because there cannot be fractional values for time.
b) the graph is discrete because there cannot be negative values for altitude.
c) the graph is continuous because there can be fractional values for time.
d) the graph is continuous because there can be negative values for altitude.

Option c

Step-by-step explanation:

Given that a hot air balloon descends to the ground.

The function

can be used to describe the altitude of the balloon as it approaches the ground.

Here t = time and h = height

Since t cannot be negative we can t starting from 0

t can take any fractional value and h is well defined for any value of t positive

So option c is right

what i would say the best answer is a. 40.5

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.
