the finalists. Solution:The prizes are RM860‚RM800 ‚RM740….. It is an arithmetic progression .The first term a=rm860 ‚ common difference d=-60 and n=20. The total amount given is Sn = n/2[ 2a + (n-1)] S26 =20/2[ 2(860) +(20-1)(-60)] =RM5800 The amount is RM 5800 2. Find the minimum number of terms that must be taken from the sequence : 4‚16‚6‚256…so that the sum is more than 400. Solution: This is a geometric sequence with a=4 and r =4 Let the minimum number of terms be n. From Sn= a(rn-1)/r-1

Malthus came up with the Malthusian Theory. In this theory he stated that the population growth would always place pressure on the ability of land and resources to support the population. Population is moving at a geometric progression‚ while land and resources moves at an arithmetic progression. Therefore the population is expanding at a more rapid pace than the land and resources that become available. It is becoming a serious problem to the world as time passes on and population still continues to

1. When a monochromatic point source of light is at a distance of 0.2 m from a photoelectric cell‚ the cut off voltage and the saturation current are respectively 0.6 volt and 18.0 mA. If the same source is placed 0.6 m away from the photoelectric cell‚ then find (a) the stopping potential (b) the saturation current 2. 663 mW of light from a 540 nm source is incident on the surface of a metal. If only 1 of each 5 × 109 incident photons is absorbed and causes an electron to be ejected from the

Dr.Gelb discusses at length how copying geometric puzzles and counting backwards by seven doesn’t reflect everyday skills. His main point about this kind of testing is the rate of change seen between tests. This rate of change can help doctors diagnose the dementia and classify it into its proper category‚ one of those being dementia of the Alzheimer’s type (Gelb). Research is being conducted in the area of Alzheimer’s itself and the disease’s progression. One set of researchers has found that

The first concepts of geometry “had their origin in simple observations stemming from human ability to recognize physical form and to compare shapes and sizes. *These types of situations brought into being the geometric concepts of vertical‚ parallel and perpendicular. * Let us sum up the history of geometry from its beginnings in peg-and-cord constructions for circles and squares. The circle and square were sacred figures and were studied by the priests for

(now the Pharaoh) is first skeptical‚ then enraged. "I am a Hebrew‚" Moses sternly advises him‚ "and the God of the Hebrews came to me and summons that you let my kin go." When Rameses dissents (and copies the slaves’ workload)‚ God unleashes a progression of disciplines. Fire downpours from the sky‚ grasshoppers slip in mists‚ and all the main conceived are slaughtered.

providing domestic energy. Timbers‚ bamboos for thatched houses are main ingredients of rural areas. Bullock-carts and agricultural implements are still largely manufactured out of timber and poles: As our population is increasing in a geometric progression‚ the pressure of population brings more and more area under cultivable land‚ the total deforested area may gradually increase.

As mentioned above‚ bacterial growth rates during the phase of exponential growth‚ under standard nutritional conditions (culture medium‚ temperature‚ pH‚ etc.)‚ define the bacterium’s generation time. Generation times for bacteria vary from about 12 minutes to 24 hours or more. The generation time for E. coli in the laboratory is 15-20 minutes‚ but in the intestinal tract‚ the coliform’s generation time is estimated to be 12-24 hours. For most known bacteria that can be cultured‚ generation times

The Foundations of Modern Society By: Damian Marton There have been countless progressions made over the course of human existence. Many of these have occurred in the last century alone‚ but I believe our greatest accomplishments transpired between (3000-500 B.C.E.).
