Mathematics

Answer: y=\dfrac{-1}{3}x+3

Step-by-step explanation:

The equation of ab line that passes through two points (a,b) and (c,d) is given by :-

(y-b)=\dfrac{d-c}{b-a}(x-a)

From the given picture , the line is passing through points (0,3) and (3,2).

Then, the equation of the line will be :-

(y-3)=\dfrac{2-3}{3-0}(x-0)

\Rightarrow y-3=\dfrac{-1}{3}x

\Rightarrow y=\dfrac{-1}{3}x+3

Hence, the required equation of the line that represents the graphed function : y=\dfrac{-1}{3}x+3

From the graph you can see easily that the y-intercept is (0,3).

The line passes thru the 2 given points (0,3) and (3,2).
                                                           2-3
Thus, the slope of this line is    m  = -------- = -1/3
                                                           3- 0

and so the equation of the graphed line is    y = (-1/3)x + 3.

Nimfa-mama [501]

Answer:

x₁ > x₂

Step-by-step explanation:

Both actions imply a parable trajectories, since both are projectile shot cases.

Let´s call x₁ maximum distance in the first case

The maximum height is just in the middle of the curve, therefore x₁ the maximum horizontal distance is equal to 60 feet.

In the second case, the parable curve is modeled by:

y = x₂*( 0.08 - 0.002x₂)    or  y = 0.08*x₂ - 0.002*x₂²

A second degree equation, solving for x₂ and dismissing the value x₂ = 0

we get:

y = 0       ⇒    x₂*( 0.08 - 0.002x₂) = 0    x₂ = 0

And 0,08 - 0.002*x₂ = 0

- 0.002*x₂ = - 0.08

x₂ = 0.08/0.002

x₂ = 40 f

Then  x₁ > x₂
