Two friends decide to go on a four-hour ride on off-road vehicles through mountainous terrain. The graph represents their elevation (in hundreds of feet) as a function of time (in hours). The ride started 2,000 feet above sea level, so for the purposes of this problem, assume the x-axis represents an elevation of 2,000 feet. Find the key features of the graph. That is, find the extrema, zeros, end behavior, increasing and decreasing intervals, and positive and negative intervals.

The elevation is positive on the interval (2,4) .

The elevation reaches a relative maximum of about 1,000 feet above the starting point.

The domain of the function is 0<x<4 .

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.
