A firefighter holds a hose 3 m off the ground and directs a stream of water toward a burning building. The water leaves the hose at an initial speed of 12 m/s at an angle of 30°. The height of the water can be approximated by h (x) = - 0.026x²+0.588x+3, where h (x) is the height of the water in meters at a point x meters horizontally from the firefighter to the building. Part: 0 / 3 Part 1 of 3 (a) Determine the horizontal distance from the firefighter at which the maximum height of the water occurs. The water reaches a maximum height when the horizontal distance from the firefighter to the building is approximately m. Round to 1 decimal place.

A firefighter holds a hose 3 m off the ground and directs a stream of water toward a burning building. The water leaves the hose
+ 0.588x+3,
at an initial speed of 12 m/s at an angle of 30°. The height of the water can be approximated by h (x) =-0.026x-
where h (x) is the height of the water in meters at a point x meters horizontally from the firefighter to the building.
Part: 0 / 3
Part 1 of 3
(a) Determine the horizontal distance from the firefighter at which the maximum height of the water occurs.
The water reaches a maximum height when the horizontal distance from the firefighter to the
building is approximately
m. Round to 1 decimal place.
