Answer:
Step-by-step explanation:
(39/7)(-12/5) = -468/35 = -13.37
Its socrates and his method is named by his name THE SOCRATIC METHOD
Using the formula S = ut +1/2at²
S=h= 20ft, u = 2ft/s, and a = 10m/s²
Thus; 20 =2t + 20t²
Therefore; 20t²+2t-20=0
Solving the equation quadratically for the value of t,
we get; t = 1.057 or t=-1.182
But t can not be negative,
Therefore, t= 1.1 seconds (to the nearest tenth)
Answer:
(-4, 3/2)
Step-by-step explanation:
(x1 + x2/2 , y1 + y2 / 2)
[-1 + (-7)/2 , -3 + 6/2]
[-8/2, 3/2]
(-4, 3/2)
