WitrynaKinetic energy must always be either zero or a positive value. While velocity can have a positive or negative value, velocity squared is always positive. Kinetic energy is not a vector. So a tennis ball thrown to the right with a velocity of 5 m/s, has the exact same kinetic energy as a tennis ball thrown down with a velocity of 5 m/s.

The radical sign '√' means we are taking the positive square root of given equation. if we simply say taking square roots on both sides,then we apply a '±' before radical ( '√') sign,as I said '√' sign means positive square root,so in order to get negative one also we apply that '±' sign. dup bolzano

Witryna22 paź 2013 · 2. Excess kurtosis = kurtosis − 3, since the normal distribution has kurtosis = 3 (that is what the "excess" refers to). Also, kurtosis is always positive, so any reference to signs suggests they are saying that a distribution has more kurtosis than the normal. Skew indicates how asymmetrical the distribution is, with more skew … Witryna15 sie 2024 · 1 2 ln ( A) + C = t + C. Now if I move C to the RHS, C would then be a positive/negative number, but I went with positive giving me the correct answer.

WitrynaAs another answer tells you, you can see that the polynomial is always positive by completing the square. Another way to see this is to note that the discriminant is negative. The discriminant for a quadratic polynomial a x 2 + b x + c is D = b 4 − 4 a c. It is a fact that the graph of y = a x 2 + b x + c crosses (or touches) the x -axis is D ...
