The function f(x) is the height of a model rocket x seconds after launch.
the rocket reaches its maximum height in 2.5 seconds and hits the ground at 5 seconds.
what is the practical domain for the function f(x)?
[0, 5]
whole numbers in [0, 5]

all real numbers

all integers in [0, 5]

all real numbers in [0, 5]

or just [0, 5]

Step-by-step explanation:

The domain is all of the possible values for the independent variable, or x-values. For this problem, it is the time in seconds.

The information we are given about seconds is:

2.5s to reach max. height

5s to hit ground

We assume it starts at 0s

The domain must include the values 0, 2.5, and 5.

Whole numbers are non-partial numbers starting 0 counting up.

Integers are non-partial numbers, positive and negative, and includes 0.

Real numbers are all partial and non-partial numbers, positive and negative.

Since the domain must include 2.5, a partial number, the domain must be real numbers. The rocket launches at 0s and stops flying after 5s, so the domain is between 0 and 5.

Domain is all real numbers in [0, 5]

pretty sure 750 each month!

step-by-step explanation:

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
