Correct Answer: D. They are both equivalent gates

Correct Answer: D. legislature

Explanation

(a)

In the diagram above, \(\alpha = 28°\) (angles in alternate segment)

\(46° + \beta + \alpha = 180°\) (angles on a straight line)

\(46° + \beta + 28° = 74° + \beta = 180°\)

\(\beta = 180° - 74° = 106°\)

\(x + \beta = 180°\) (opposite angles of a cyclic quadrilateral)

\(x + 106° = 180°\)

\(x = 180° - 106° = 74°\)

Hence, < VUS = 74°.

(b) Total surface area = curved surface area + area of closed end

= \(2\pi rh + \pi r^{2}\)

= \(\pi r(2h + r)\)

\(462 = \frac{22r}{7}((2 \times 7) + r)\)

\(\frac{462 \times 7}{22} = r(14 + r)\)

\(147 = 14r + r^{2}\)

\(r^{2} + 14r - 147 = 0\)

\(r^{2} - 7r + 21r - 147 = 0\)

\(r(r - 7) + 21(r - 7) = 0\)

\((r + 21)(r - 7) = 0\)

\(r = \text{-21 or 7}\)

The radius cannot be negative, therefore, r = 7 cm.

Correct Answer: A) Aestivation

Explanation

The question is asking about the inactive state that animals exhibit during hot dry seasons. This state is called aestivation. Aestivation is a period of inactivity similar to hibernation, but it occurs during hot, dry periods instead of cold, winter months. During aestivation, animals reduce their metabolic rate and conserve water to survive the harsh environmental conditions. Some animals that aestivate include snails, lungfish, some species of rodents, and certain reptiles and amphibians. It is important to note that aestivation is different from dormancy, which is a state of suspended growth and metabolism, and resting, which is a state of reduced activity but not complete inactivity. For more information, please see the recommended textbooks.

TECHNOLOGY HAS MADE THE WORLD A BETTER PLACE

Good morning Mr. Chairman, panel of Judges, accurate time keeper, co-debaters, ladies and gentlemen. Am here today to support the motion that states that 'Technology has made the world a better place'.

It is through technology that the world came to embrace modern ways of life through the use of television, car, radio, telephone, etc. In the past the people lived an archaic and primitive existence until technology was embraced and today life has been made easier for everyone via technology. Technology has helped us and it is still helping us to live longer. In the past people died without anybody fathoming the causes of their death until technology came in and helped in unraveling the causes of death. The magic was done through the invention of equipment that run tests on humans to detect the causes, nature, symptoms and cures of illnesses.

It is also through technology that we are able to communicate effectively with one another. In the past communicating with distant friends. relations, etc. was done via only letter writing but the advent of technology gave us telephone and now mobile phones. Today one does not have to write often because one can sit in the comfort of one room and within seconds communicate with anybody in any part of the world. Likewise. everybody now has a mobile phone with them and can communicate with ease.

Technology has also made work easier via the use of computer. Today we have computers in our various homes and offices which help us to work fast with ease. People now abhor doing things manually and have resorted to the use of computer for communication and business transactions. Think of how the world would be without computers in our homes and offices. Technology has made the world a better place to live in because it has given us the engineering used in building good roads, houses, cars and bridges across the world.

Technology has made the world a better place through the invention of airplanes which can travel to any part of the world in the speed of lightning. In the past people spent days, weeks and months to get to any part of Africa, Europe and America. The journeys were usually fraught with dangers but the airplanes have made travelling from one continent to another continent easier and fun to embark on.

Technology has made the world a better place to live in with the advent of electricity. In the past people lived in the dark because of the absence of power. People tend to retire early to bed once it was evening. But the situation has changed today because power is now generated to give us night visibility. We now go about our social life and businesses even late into the night because of power generation.

Therefore, ladies and gentlemen. I stand here today purely convince in my mind that technology has made the world a better place to live in for everybody.
