x2−4x+3=0
For this equation: a=1, b=-4, c=3
1x2+−4x+3=0
Step 1: Use quadratic formula with a=1, b=-4, c=3.
x=
−b±√b2−4ac

Answer:
Step-by-step explanation:
K.E. =
m
So,
=1/2 x 113 x 0.5 x 0.5
=1/2 x 1/2 x 1/2 x 113 (Because, 0.5 = 1/2)
=1/8 x 113
= 14.125 J
Answer: i'm not really sure how to answer this one but i think you're wanting an answer to something. the equation for it would be 5 + 5x meaning the 5 is already there, and x is for the minutes that are they filling it up. so if the question asks how much after 5 minutes, you simply just put the 5 in place for the x.
The answer is d it has to be
