Answer:  A) 39,366        B) 61

<u>Step-by-step explanation:</u>

A) -2, -6, -18, -54, ....

each following term is multiplied by 3 so it is a geometric series

a_n=-2(3)^{n-1}\\\\\\a_{10}=-2(3)^{10-1}\\.\quad =-2(3)^{9}\\.\quad =-2(19,683)\\.\quad =\boxed{-39,366}

B) 7, 9, 12, ...

each following term is +n, so it is neither arithmetic or geometric

7 + 2 = 9

9 + 3 = 12

12 + 4 = 16

16 + 5 = 21

21 + 6 = 27

27 + 7 = 34

34 + 8 = 42

42 + 9 = 51

51 + 10 = 61           The 10th term is 61

everyone's indiviaual demand for a particular good or service can be represented by the same demand curve
bija089 [108]

The statement "everyone's individual demand for a particular good or service can be represented by the same demand curve " is false. Option B

This is further explained below.

<h3>What is the demand curve?</h3>

Generally, In the field of economics, a demand curve is a graph that illustrates the relationship between the price of a particular commodity and the quantity of that commodity that is demanded at that price. Specifically, the graph shows how the quantity of a commodity is affected by the price of the commodity.

Demand curves may be used to analyze the price-quantity connection for a single customer, or they can be used to analyze the relationship for all consumers in a certain market.

In conclusion, It is a fallacy to assert that "everyone's individual need for a given commodity or service can be represented by the same demand curve."

Answer:

x = 5

Step-by-step explanation:

Add the degrees of m<VUJ and m<JUT and make them equal to 175 since both angles exist with m<VUT.

17x - 3 + 17x + 8 = 175

34x - 3 + 8 = 175

34x + 5 = 175

34x = 170

x = 5
