One of the construction workers likes to listen to music on the job. Unfortunately, he also has a bad habit of accidentally dropping his music player into the ravine! Luckily, his daughter is good with physics and has built a safety balloon for his latest music player that will release after the music player has been falling for 1 second. The time it takes for the music player to fall from the bridge to the bottom of the ravine can be modeled by the following equation:

where t is the amount of time since the construction worker dropped his music player.

Will the safety balloon release in time?

1. Your solution produces two roots, but you should make sure that both times are valid. Check your work by plugging each root back into the original equation and simplifying each expression. Identify the answer that is actually a solution. (2 points: 1 point for each time)

2.Will the music player land safely? How do you know?

Helena lost her marbles. but then she found them and put them in 44 bags with mm marbles in each bag. she had 33 marbles left over that didn't fit in the bags.

If f(x)=x+7 and g(x)=1/x what is (fog)(x)

Name and describe the three most important measures of central tendency. choose the correct answer below. a. the mean, sample size, and mode are the most important measures of central tendency. the mean of a data set is the sum of the observations divided by the middle value in its ordered list. the sample size of a data set is the number of observations. the mode of a data set is its highest value in its ordered list. b. the sample size, median, and mode are the most important measures of central tendency. the sample size of a data set is the difference between the highest value and lowest value in its ordered list. the median of a data set is its most frequently occurring value. the mode of a data set is sum of the observations divided by the number of observations. c. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is the product of the observations divided by the number of observations. the median of a data set is the lowest value in its ordered list. the mode of a data set is its least frequently occurring value. d. the mean, median, and mode are the most important measures of central tendency. the mean of a data set is its arithmetic average. the median of a data set is the middle value in its ordered list. the mode of a data set is its most frequently occurring value.
