Suppose the distance from the light to the man at time t is x(t), and that the length of his shadow is s(t).By similar triangles, (x + s)/s = 15/6 = 5/2
That is, x/s + 1 = 5/2 so that x/s = 3/2
and therefore, s = 2x/3
Then since dx/dt = 5 feet/sec, ds/dt = 2/3*5 ft/sec = 10/3 ft/sec or 3.33... (recurring) ft/sec
yes very much. he was married twice and his first marriage lasted 10 years and the second lasted 20
Assuming that you travel 882 feet in a straight line, the average velocity is 882.5 = 176.4 feet per second.
x² + x² = 2x²
It is a polynomial expression in x. What about it?
The first expression, y = 4, would be a horizontal line at y = 4. The second expression can be found by setting y equal to zero and solving for x, and, likewise, setting x equal to zero and solving for y: 2x = 2 <=> x = 1, so coordinate is (1,0) y = 2, so coordinate is (0, 2) Now draw a line connecting those two points and beyond them.

To make perpendicular lines, draw a horizontal line. Then using a compass or tracing around the edge of a curved object, draw one circle ( or just a semi-circle) so that it crosses the horizontal straight line in at least one point. Now rotate the compass or move the curved object to draw another circle (or semi-circle). This second circle (or semi-circle) must cross through the horizontal straight line as the first one did. It also must cross through the first circle (or semi-circle) at two points- above the horizontal straight line and below the horizontal straight line. Next, draw a straight line from where the two circles (or semi-circles) meet above the horizontal straight line through to where they meet below the horizontal straight line. You now have a line perpendicular to the first line.
Constant speed
If the non-horizontal projectile is launched abovehorizontal, thenit's the second one to hit the ground, after the horizontal one.If the non-horizontal one is launched below horizontal, then it'sthe first to hit the ground, before the horizontal one.

The Walking Dead seasons air from October to March.
While you are walking across a horizontal floor at a constant velocity, the force your hand exerts on the bag does no work. However, when you ascend an escalator, the force does perform work on the bag. Why? To do work is to change the energy of an object. In this case we have either kinetic energy, or gravitational potential energy. The first case we are walking on a horizontal floor, there is no change in height, thus no change in potential energy. We are also moving at a constant speed, thus no change in kinetic energy. If we sped up, or slowed down, then we would do work. In the second case, we are ascending an escelator, and changing the height. This changes the gravitational potential energy, and thus does work.
First: horizontal: Abscissa Second: vertical: ordinate.
Second star to the right and straight on 'till morning.
Divide the motion into a horizontal and a vertical component. The horizontal component won't be affected by gravity. The vertical component will get a downward acceleration of 9.8 meters per second per second.
Take the second left then drive straight on for a mile.Go straight to the headmistress' office now!The wine was going straight to her head.
