The answer to 21 is Never true because a supplementary angle always adds up to 180 degrees and obtuse angles are angles MORE than 90 degrees and 91 + 91 wouldn't make it supplementary.

<span>Please, post only one question at a time.

The line passing through (1,4) and (-4,-1) has the following slope:

-1 - 4 -5
m = ------------ = -------- = +1
-4 - 1 -5

Find the slope of the line passing thru the other set of points. Graph both lines. What do you see? Do the 2 lines have any particular relationship to one another?

You toss a rock of mass m vertically upward. Air resistance can be neglected. The rock reaches a maximum height h above your han

laiz [17]

Answer:

$v=\sqrt{\frac{3gh}{2}}$

Step-by-step explanation:

If air resistance is neglected, the energy is constant. That means that in every point in the trajectory the energy is the same.

At the point of height h, all the energy is potential and velocity is zero (no kinetic energy)

$E=mgh$

At point of height h/4, some of the potential energy has transformed in kinetic energy and the velocity is no longer zero. But we know the total amount of energy is the same as the maximum height point.

With that information, we can calculate the velocity v:

$E=mg(\frac{h}{4})+m\frac{v^2}{2}=mgh\\\\m\frac{v^2}{2}=mg(h-\frac{h}{4})\\\\\frac{v^2}{2}=\frac{3gh}{4}\\\\v^2=\frac{3gh}{2}\\\\v=\sqrt{\frac{3gh}{2}}$
