Question

Just need a bit of help getting started...

Answer 1

You need to draw a tangent to the curve at the point (4, 9). Then estimate the slope of the tangent and consider its sign.

Answer 2

I know, but I don't really know how yet

Answer 3

I don't know why I don't, since when we do it in class I'm fine, but I'm drawing a blank

Answer 4

ill try :3

Answer 5

vcongruent(dr)/(dt),
where r is the radius vector and d/dt is the derivative with respect to time. Expressed in terms of the arc length,
v = (ds)/(dt)T^^,
where T^^ is the unit tangent vector, so the speed (which is the magnitude of the velocity) is
vcongruent|v| = (ds)/(dt) = |r'(t)|.

Answer 6
