The height of a ball in feet can be found by the formula h(t) = - 16 t2 + 80 t where t' is the elapsed time in seconds.
Find the time that the ball hit the ground to the nearest
tenth of second.

Plz, ! the box plot below shows the total amount of time, in minutes, the students of a class surf the internet every day: a box plot is shown.part a: list two pieces of information that are provided by the graph and one piece of information that is not provided by the graph. (4 points) part b: calculate the interquartile range of the data, and explain in a sentence or two what it represents. (4 points) part c: explain what affect, if any, there will be if an outlier is present. (2 points)

Can someone me with this problem . show your work .

Consider that lines b and c are parallel. what is the value of x? what is the measure of the smaller angle?
