# Why you need more than one coordinate system?

That is because - for example - some calculations are easier in polar coordinates, and some are easier in rectangular coordinates. For example, complex numbers are easier to add and subtract in rectangular coordinates, and easier to multiply and divide in polar coordinates.

### How does an ordinate differ from a coordinate?

There are slight differences between a coordinate and and ordinate. In mathematics, an ordinate is plotted on the vertical axis of a two dimensional system and is an element of an ordered pair. A coordinate however, refers to a geometry system which uses one or more than one number to chart and determine the position of a point or other geometic element.

### What is the axes of a rectangle?

First, a coordinate. A coordinate is a number. It labels a point on a line. Second, a coordinate axis is a line with coordinates. to label a point in a plane (a flat surface), we need more than one coordinate axis, and we place a second at right angles to the first. Those axes are called rectangular coordinate axes, because they are at right angles to one another. The coordinates on them are called rectangular…

### Why is the north bridge faster than the south bridge?

The Northbridge coordinate the comunication and is the main interface between CPU, Graphical Interface Card and the Memory (RAM). Those need more speed and are the most used components in the computer. The Southbridge coordinate and is the interface between Storage units, USB ports, expansion cards (not PCI express), and other devices on computer. Those need less speed on data tranmission. The comunication between northbridge and southbridge is coordinate by the northbridge.

### Does 110vac more economical than 220vac?

No. As the voltage drops you need higher current to transfer the same amount of power, and higher currents need thicker cables with more metal in them. And more metals means more money. Also, if you lose 2 V through resistance in cables, then that's proportionally bigger in a 110V system than in a 220V system.

### Can you solve system of equations by graphing?

Yes you can, if the solution or solutions is/are real. -- Draw the graphs of both equations on the same coordinate space on the same piece of graph paper. -- Any point that's on both graphs, i.e. where they cross, is a solution of the system of equations. -- If both equations are linear, then there can't be more than one such point.

### How much effort is needed to lift a 75 N weight using the pulley system?

If you are talking about a simple pulley with the pulley attached and load rope attached to the object then you will need a little more than 75N of force. Lifting an object (at a constant velocity) requires a force equal but opposite the weight of the object. With any simple machine you will need to do more work to overcome friction. If you were to use a single pulley with the pulley attached to…

### The planet that contains more than half the mass of the solar system not in the sun?

Jupiter has more mass than all the other planets (in the Solar System) together. Jupiter has more mass than all the other planets (in the Solar System) together. Jupiter has more mass than all the other planets (in the Solar System) together. Jupiter has more mass than all the other planets (in the Solar System) together.

### What is memory mangment?

The memory management subsystem is one of the most important parts of the operating system. Since the early days of computing, there has been a need for more memory than exists physically in a system. Strategies have been developed to overcome this limitation and the most successful of these is virtual memory. Virtual memory makes the system appear to have more memory than it actually has by sharing it between competing processes as they need…

### Is it more effective to take medication anally than orally?

It depends on the type of medication and the recommended route of administration. Some meds would never break down if put into the anus and rectum, no matter how long you tried to hold them in. Conversely, some meds are made specifically to dissolve in the rectum and would be disgusting to try to put into the mouth. Other meds are topical (they go on the skin), so neither anal-rectal nor oral would be okay…

### Why are digital system capable of accuracy than analog system?

digital systems have definite defined states, analog systems have continuous states with no definite value. if you need more defined states they can be added in a digital system simply by adding more bits to the value, in an analog system more uniquely defined values can only be added by using expensive precision tolerance components. more states/values = more accuracy
