Answer:

  • D. 5.7 km/h north and 5.8 km/h west are instantaneous velocities, while 8.1 km/h northwest is the average velocity.

Step-by-step explanation:

We are given directions and position change.

This is about the velocity, the speed doesn't take into account the direction.

We also see the change in the velocity. The numbers give us instantaneous velocities and the displacement is the average velocity as the sum of vectors.

Considering the above explanation, correct choice is D.

What is the vertex of the graph of g(x)=|x-9|+3
mart [117]

Look at h(x) = |x-9|. The vertex of this absolute value function graph is at (9,0).


Sometimes it helps to work on a simpler problem first, which is why I've introduced h(x) = |x-9|.


The vertex of g(x)=|x-9|+3 is 0+3, or 3; we translate the entire graph of g(x)=|x-9| upward by 3 units. Thus, the vertex of g(x) is (9,3).

Solve the equation sine Ф=0.6792 for 0°≤Ф≤360
Sergio [31]

Answer:

42.78⁹, 137.22⁹.

Step-by-step explanation:

sine Ф=0.6792

Angle Ф in the first quadrant = 42.78 degrees.

The sine is also positive in the second quadrant so the second solutio is

180 - 42.78

= 137.33 degres.
