Review the graph. On a coordinate plane, vector u has origin (negative 2, 3) and terminal point (6, 3).

What are the characteristics of the vector shown?

magnitude of 8 and direction angle equal to 0°
magnitude of 8 and direction angle equal to 180°
magnitude of 2 StartRoot 2 EndRoot and direction angle equal to 0°
magnitude of 2 StartRoot 2 EndRoot and direction angle equal to 180°

A, Magnitude of 8 and direction angle equal to 0°

Step-by-step explanation:

Since vector u is only a straight line, there will be no angle, which means that answers B and D are automatically wrong.

Now, we’re going to use the distance formula to find the component form of vector u

Now we found the new coordinate, which is (8,0), and it is being extended from the origin with the same angle of 0°

Using the formula from above, we can find the magnitude of vector u

Hope I explained it well and hopefully this helps!

A) magnitude of 8 and direction angle equal to 0°

Step-by-step explanation:

got it right on edge :)

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
