An object moves along the x-axis so that at any time t ≥ 0, its velocity is given by v(t) = 4 − 3.8 cos(0.7t). What is the acceleration of the particle at time t = 6?
A= -0.913
B=1.098
C=-2.318
D=5.863

The width of a rectangle is 20 units. can the perimeter p of the rectangle be 64 units when its length x is 11 units? no, because p = 2x + 2(20) no, because p ≠ 2x + 2(20) yes, because p ≠ 2x + 2(20) yes, because p = 2x + 2(20)
