The height of a rocket a given number of seconds after it is released is modeled by h (t) = negative 16 t squared + 32 t + 10. W
2 answers:
Answer: The variable t stands for the number of seconds since the rocket was launched.
Step-by-step explanation:
Given:
The rocket's height over time is represented by the equation:
Here, the variable t denotes the elapsed seconds after the rocket's release.
The initial velocity can be found by differentiating the height function with respect to time:
Evaluating at t=0:
Therefore, the rocket's initial velocity is 32 units per second.

Answer:
The sales figure for the third year is .
Step-by-step explanation:
Since sales data for the second year is unavailable, we denote it as x million.
Year 3's total sales amount to 32 million.
Calculate the sales account for year 3 as follows:
Answer:
The mean decreases, while the median stays unchanged.
Step-by-step explanation:
A box plot is constructed from the quartiles of the data distribution, incorporating the maximum and minimum values. From this, one can determine the range, median, and interquartile range.
In this scenario, the median maintains its value at $9.5 per hour. The median is represented by the middle line in the box, which remains constant.
Conversely, the range of this data set shrinks from 7 to 3.
Moreover, the mean must decrease because values greater than $11 are no longer represented in the second box plot. The mean is a measure sensitive to such alterations.
Conclusively, the correct finding is The mean decreases, while the median remains unchanged.
