The horizontal distance from the firefighter at which the maximum height of water occurs is 10.83m
<u>Explanation:</u>
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
2x+4y=8
-2x -2x
4y=-2x+8
/4 /4 /4
y=-1/2x+2
The green arrow thing is a ray. So, question b. is a ray. So the dot would be B and the arrow would be C.
Answer:
-6 and -3 for the dots
