Answer:
C
Step-by-step explanation:
Acceleration is the change of velocity per unit change of time. In this case, given the velocity equation, we can get the acceleration of the particle by taking the first derivative of the equation. v'(t)= t^2 (1/t+2) + 2t In(t+2). substituting t= 6, acceleration is equal to 29.45 m/s2.
Answer:
y=−9x and y=−4
Step-by-step explanation:
We know that
the perimeter of a circumference=2*pi*r
<span>If the perimeter of a sector is 4 times its radius, then the arc measure of the sector is (4r-2r)----> 2r
so
if 2*pi radians (full circle) has a length------------------> 2*pi*r
X radians -------------------------------------------> </span>2*r (the sector)<span>
X=2*r*(2*pi)/(2*pi*r)-----> x=2
the answer is
2</span>
