tigry1 [53]

41.9 mi

Step-by-step explanation:

First, we convert the angle from degree measure to radian measure:

$\theta = 240°×\left(\dfrac{\pi}{180°}\right)= \dfrac{4\pi}{3}\:\text{rad}$

For what values of t, if any, is given vector parallel to vector u = (4,-1): (8t, 2t)? and (1,t^2)?

Radda [10]

The vector would have to be a scalar of (4,-1) in order to be parallel to it
so
4 = 8t -1 = 2t

t= 4/8 = 1/2
-1=2t
t= -1/2
