Find d(21) in the sequence given by d(n) = 2+0.4(n-1). d(21)=

Answers

Answer 1

Answer: 8

Explanation:

From the question, we are informed that we should find d(21) in the sequence given by d(n) = 2+0.4(n-1). This will be:

d(n) = 2+0.4(n-1)

d(21) = 2 + 0.4(21 - 1)

= 2 + 0.4(20)

= 2 + 8

= 10

Therefore, based on the above calculation, we can deduce that the 21st term is 8.

Evacuation in the Soviet Union was the mass migration of western Soviet citizens and its industries eastward as a result of Operation Barbarossa, the German military invasion of June 1941. Nearly sixteen million Soviet civilians and over 1,500 large factories were moved to areas in the middle or eastern part of the country by the end of 1941.[1] Along with the eastern exodus of civilians and industries, other unintended consequences of the German advances saw the execution of previously held western state civilians by Soviet NKVD units,[citation needed] the removal of Lenin's body from Moscow to Tyumen, and the relocation of the Hermitage Museum collection to Sverdlovsk, Kuybyshev, the alternative capital of the Soviet Union 1941-1943. Soviet towns and cities inland or in the east received the bulk of the new refugees and high priority war factories, as locations such as the Siberian city of Novosibirsk, received more than 140,000 refugees and many factories due to its location away from the front lines. Despite early German successes in seizing control of large swaths of the western USSR throughout 1943, and semi-prepared contingency plans by the Soviets in their mobilization plans to the east, Soviet industries would eventually outpace the Germans in arms production, culminating in 73,000 tanks, 82,000 aircraft and nearly 324,000 artillery pieces being dispersed throughout the Red Army in their fight against the Axis Powers by 1945.[2]

A quadrilateral has a perimeter of 207 units and one side measures 36 units. The lengths of the other three sides are in the ratio of 5:6:8. Find the lengths of the three missing sides.

Answers

Answer:

45, 54, 72

Explanation:

In this case, a quadrilateral is like a square, with 4 sides but it's sides are longer than a square.

The perimeter of any geometrical figure is the sum of all the side's lenght, so, if we have the perimeter and the value of one side, we can deduce the lenght of the other sides because we have a data of the ratio. Let's first see how much is left on the missing sides.

P = a + b + c + d

207 = 36 + b + c + d

171 = a + b + c

This means that the sum of the other 3 sides is 171. We know that the ratio of those sides is 5:6:8, so the sum of these sides can be written like this, in function of those ratios:

171 = 5x + 6x + 8x

171 = 19x

x = 9

With this number we can now calculate the sides of the quadrilateral:

a = 5x = 5 * 9 = 45

b = 6x = 6 * 9 = 54

c = 8x = 8 * 9 = 72

Therefore the missing sides's lenght are:

45, 54, 72

How does physical geography influence whether intensive or extensive agriculture is used?

Answers

Answer:

Intensive farming is done where land recourse is limited.

Explanation:

Yes, physical geography (land forms, soil types, climate etc.) greatly influence the type of agricultural practice used.  

Intensive farming is practised where land resource is limited so that higher output is yielded from the same patch of land. Opposite to this extensive farming is practiced to increase yield by bringing more and more land under cultivation. Here land is not a limited resource.

How did the geography of Greece lead to the Peloponnesian War?
I NEED HELP ASAP

Answers

Answer:

due to property of king

Explanation:

ok


The Peloponnesian War was a war fought in ancient Greece between Athens and Sparta—the two most powerful city-states in ancient Greece at the time (431 to 405 B.C.E.). This war shifted power from Athens to Sparta, making Sparta the most powerful city-state in the region. The war featured two periods of combat separated by a six-year truce.

Athens and Sparta had previously quarreled in the decades prior to the war. One of Sparta’s allies, Corinth, had directly engaged the Athenian army. As a Spartan ally, Corinth resumed hostilities toward Athens when Athens threatened Corinth’s interests in the region surrounding Corcyra. This eventually drew Sparta into the conflict. The Spartan army began by raiding lands within an Athenian allied territory, particularly a region near Athens called Attica. The Athenians had built walls stretching from their seaport to the city of Athens. The walls helped protect Athens from direct assault, and its leader, Pericles, urged Athens not to engage in direct land battles with the Spartans. Instead, the Athenians used their navy to deliver troops into the Spartan territory to conduct raids on settlements.

After years of open warfare, Sparta offered peace and Athens accepted. The agreement was made official with the signing of the Peace of Nicias. The treaty stated that Athens and Sparta would defend each other for the next 50 years. However, the treaty only lasted six.

Hostilities resumed between Athens and Sparta with an assault launched by the Athenians at Sicily. Sparta decided to retaliate. Learning from its past experiences with the Athenian navy, they established a fleet of warships. It would be another decade of warfare before the Spartan general Lysander defeated the Athenian fleet at Aegospotami. This defeat led to Athenian surrender. As a result, the Peloponnesian War was concluded. Simultaneous to the end of this conflict came the end of the golden age of ancient Greece.

Determine which type of segments are in the picture below. Based on the properties above, explain how to solve for x. Give as much detail as possible

Answers

Answer/Explanation:

The type of segments given in the picture are called secants.

The two secants meet at a point (A) outside the circle.

✅Thus, based on the secant -secant theorem:

AB*BC = AD*DE

AB = 4

BC = 8

AD = 3

DE = x

Plug in the values

4*8 = 3*x

32 = 3x

Divide both sides by 3

32/3 = x

10.67 = x

x = 10.67
