The water reaches a max height when the horizontal distance from the firefighter to the building is approximately __m. Round to 1 decimal place

The horizontal distance from the firefighter at which the maximum height of water occurs is 10.83m

Explanation:

Given:

h(x) = -0.026x² + 0.563x + 3

where,

h(x) is the height of the water

Initial speed, u = 14m/s

angle, θ = 30°

(a)

Horizontal distance = ?

h(x) = ax² + bx + c

the vertex is found at x = -b/2a

where,

x = distance to the maximum height

As compared to the equation given:

a = -0.026

b = 0.563

Thus,

Therefore, horizontal distance from the firefighter at which the maximum height of water occurs is 10.83m

d is the correct answer

step-by-step explanation:

x= 8 because 3x = 3 * 8, and 3*8 = 24

yes
