How is this even a real question? None of this depends on stats or factual evidence, it is all based on if they feel good, they want to build a model train, or maybe if they have to eat dinner in between. I honestly don't know how you are going to get an answer to this question :/ Tell whoever asks you the question that they need to reword it

Whats the slope of (-3,4) (0, 0)
Maurinko [17]

Answer:

slope = -\frac{4}{3}  

Step-by-step explanation:

Use the slope formula, m = \frac{y_2-y_1}{x_2-x_1}, to find the slope. m represents the slope. x_1 and y_1 represent the x and y values of one point, and x_2 and y_2 represent the x and y values of another point. So, substitute the x and y values of the points (-3, 4) and (0, 0) into the formula appropriately and solve:

m= \frac{(0)-(4)}{(0)-(-3)} \\m = \frac{0-4}{0+3} \\m = \frac{-4}{3}

Thus, the slope is -\frac{4}{3}.

mr Goodwill [35]

Answer:

v=26.41 m/s

Step-by-step explanation:

From the Newtons laws of motions, we sew that x= (2v₁²sin∅os∅)/g where x is the horizontal distance v is the initial speed and ∅ is the launch angle.

From trigonometry we see that 2 sin∅cos∅=sin 2∅

Therefore,  x=(v²sin2∅)/g

x=22m

∅=9°

g=9.8m/s²

22m=v²×sin(2×9)/(9.8m/s²)

v²=(22×9.8)/(sin 18)

v²=697.696

v=√697.696

v=26.41 m/s
