8 0

(y - yo) = m.(x - xo)

(4 - 0) = m.(0 - (-5))

4 = m.5

m = 4/5

(y - yo) = 4/5.(x - xo)

(y - 4) = 4/5.(x - 0)

y = 4x/5 + 4

5. The Riverside Geyser in Yellowstone National Park erupts

Anastasy [175]

Answer:

Step-by-step explanation:

The equation for the model of the geyser is found by substituting the given upward velocity into the vertical motion model. The problem statement tells us v=69. We assume the height is measured from ground level, so c=0. Putting these values into the model gives ...

h(t) = -16t² +69t

The maximum height is at a time that is halfway between the zeros of the function.

h(t) = -16t(t -4.3125) . . . . . has zeros at t=0 and t=4.3125

The maximum height will occur at t=4.3125/2 = 2.15625 seconds. The height at that time is ...

h(t) = -16(2.15625)(2.15625 -4.3125) = 16(2.15625²) ≈ 74.39 . . . feet

The maximum height of the geyser is about 74.4 feet.
