function: f(x)= -x^2+2

true or false:
when f(x) =2, x= -2

Answer:

True

Explanation:

Step 1: Define

f(x) = -x² + 2

x = -2

Step 2: Substitute and Evaluate

f(-2) = -(-2)² + 2

f(-2) = -4 + 2

f(-2) = -2

A student adds two displacement vectors that have the magnitudes of 15.0 m and 5.0 m. What is the range of possible answers for the magnitude of the resultant vector?

(1) Hong Kong is one of the most densely populated places on Earth: people crowd into tiny living spaces, some with only a bed, a hot plate, and a toilet. (2) The city is made up of more than 200 islands, and there is no more available land to house its people. (3) To solve this land shortage problem, officials have proposed a radical solution: creating a whole new island. (4) The East Lantau Metropolis would be built on land reclaimed from the sea and would house 1.1 million people.

(5) A different problem faces the people of Kiribati—a nation in the central Pacific Ocean made up of 33 islands (most of which are less than twenty feet above sea level). (6) Because of rising sea levels, some inhabitants have already had to abandon their homes. (7) New islands will have to be built to ensure a safe future for its citizens, because science indicates that Kiribati will go underwater within the century.

(8) Artificial islands have been seen as solutions for a number of problems in recent decades. (9) The city of Dubai has been constructing a luxurious palm-tree-shaped series of islands to house hotels. (10) Osaka, Japan, built an island off its coast to relieve its overcrowded airport. (11) The Maldives, Malaysia, and Seoul have all built or have plans to build artificial islands to expand their territory.

(12) So, is building artificial islands a good solution for modern-day challenges? (13) Not everyone thinks so. (14) Constructing artificial islands destroys the coral reefs that nourish fisheries and protect the coastline from the impact of waves; it also destabilizes precious coastal ecosystems. (15) Building on unstable dredged sediments also endangers human inhabitants, especially in areas prone to earthquakes.

D)The government of South Korea expected to have 300,000 residents in the utopian smart city built on the artificial island of Songdo.


E)Environmental scientists at Macquarie University in Sydney, Australia, have noted that those building artificial islands can use techniques like silt curtains to help minimize the environmental impact of these projects.

Refer to the passage.

"The next day (25th May) (the Chan) sent his secretaries to me, who said: ‘Our lord sends us to you to say that you are here Christians, Saracens [Muslims] and Tuins. And each of you says that his doctrine is the best, and his writings—that is, books—the truest. So he wishes that you shall all meet together, and make a comparison, each one writing down his precepts, so that he himself may be able to know the truth.’ Then I said: ‘Blessed be God, who put this in the Chan’s heart. But our Scriptures tell us, the servant of God should not dispute, but should show mildness to all; so I am ready, without disputation or contention, to give reason for the faith and hope of the Christians, to the best of my ability.’ They wrote down my words, and carried them back to him. Then it was told the Nestorians that they should look to themselves, and write down what they wished to say, and likewise to the Saracens [Muslims], and in the same way to the Tuins.”
