Answer:

f(x) = 3 if x ≤ -2

= 1 if x > -2 ⇒ attached figure

Step-by-step explanation:

* Lets explain how to answer the question

- For the part of the graph on the left side (2nd quadrant)

- There is a horizontal line start from x = -∞ and stop at x = -2

- The end of the line is black dot means x = -2 belongs to the function

- The horizontal line drawn at y = 3

∴ The equation of the horizontal line is y = 3

∴ The function represents this part of graph is y = 3 if x ≤ -2

- The other part of the graph is also horizontal line start from

x = -2 to x = ∞

- The end of the line is white dot means x = -2 does not belong

to the function

- The horizontal line drawn at y = 1

∴ The equation of the horizontal line is y = 1

∴ The function represents this part of graph is y = 1 if x > -2

* f(x) = 3 if x ≤ -2

= 1 if x > -2

- The answer is attached

Answer:

4968.6 m from where it was fired
221.33 m/s

Step-by-step explanation:

For the purpose of this problem, we assume ballistic motion over a stationary flat Earth under the influence of gravity, with no air resistance.

We can divide the motion into two components, one vertical and one horizontal. For muzzle speed s and launch angle θ, the horizontal speed is presumed constant at s·cos(θ). The initial vertical speed is then s·sin(θ) and the (x, y) coordinates as a function of time are ...

(x, y) = (s·cos(θ)·t, -4.9t² +s·sin(θ)·t + h₀) . . . . . where h₀ is the initial height

To find the range, we can solve the equation y=0 for t, and use this value of t to find x.

Using the quadratic formula, we find t at the time of landing to be ...

t = (-s·sin(θ) - √((s·sin(θ))²-4(-4.9)(h₀)))/(2(-4.9))

t = (s/9.8)(sin(θ) +√(sin(θ)² +19.6h₀/s²))

For s = 220, θ = 45°, and h₀ = 30, the time of flight is ...

t ≈ 31.939 seconds

Then the horizontal travel is

x = 220·cos(45°)·31.939 ≈ 4968.6 . . . . meters

As it happens, the value under the radical in the above expression for time, when multiplied by s, is the vertical speed at landing. The horizontal speed remains s·cos(θ), so the resultant speed is the Pythagorean sum of these:

landing speed = s·√(cos(θ)² +sin(θ)² +19.6h₀/s²) ≈ s√(1 +0.012149)

≈ 221.33 m/s

_____

Note that the landing speed represents the speed the projectile has as a consequence of the potential energy of its initial height being converted to kinetic energy that adds to the kinetic energy due to its initial muzzle velocity.
