Answer:

Columns without leading 1's in a reduced row-echelon form of the augmented matrix are called free variables. So, yes it will have 2 free variables corresponding to the two columns without leading 1. In homogeneous system it remains true.

The position function of a particle in rectilinear motion is given by s(t) = 2t^3 - 21t^2 + 60t + 3 for t ≥ 0. Find the position
avanturin [10]
Your first and second derivatives which are the velocity and the acceleration respectively are correct.
The particle has reverses direction when v(t) ≤  0 so at interval 2 < t < 5 sec.
You can substitute now t = 2 for s(2) and a(2) for first changing direction. Also t = 5 for s(5) and a(5) for second changing direction.

Find the length of side x in simplest radical form with a rational denominator.
aleksandrvk [35]

Answer:x = 7√3/3

Step-by-step explanation:

The given triangle is a right angle triangle. To determine the value of x, we would apply trigonometric ratios of tan but the opposite side and adjacent sides would depend on the reference angle used. Taking 30 degrees as the reference angle,

Tan # = opposite side/adjacent side

Opposite side = x

Adjacent side = 7

# = 30 degrees

Therefore,

Tan 30 = x/7

x = 7tan30 = 7 × 1/√3 = 7/√3

= 7/√3 × √3/√3 = 7√3/3
