first three terms of a sequence are given. Round to the nearest thousand (if necessary) 152,149,146... Find the 30th term

Answers

Answer 1

Answer:

Step-by-step explanation:

use the following equation

aₙ=a₁+(n-1)d

Where d is the common difference

n is the term

a₁ is the first term

the common difference is -3 (149-152)

this means we have

152+(30-1)*-3

Compute this and get

what is the other endpoint of a segment with one endpoint at(-3, 8) and the midpoint at (7, 1)?

Answers

Answer: The other point is (17, -6).

Step-by-step explanation:

Midpoint (x,y) of the line segment joining (a,b) and (c,d) is given by :-

[tex](x,y) =(\dfrac{a+c}{2}, \dfrac{b+d}{2})[/tex]

Here, we need to find the other endpoint of a segment with one endpoint at(-3, 8) and the midpoint at (7, 1).

Let other point be (a,b), then

[tex](7,1)=(\dfrac{-3+a}{2},\dfrac{8+b}{2})\\\\\Rightarrow\ \dfrac{-3+a}{2}=7\ \text{ and }\dfrac{8+b}{2}=1\\\\\Rightarrow\ -3+a = 7\times2 \text{ and } 8+b=1\times2\\\\\Rightarrow\ -3+a=14\text{ and }8+b=2\\\\\Rightarrow\ a=14+3, \ \ \ b= 2-8\\\\\Rightarrow\ a=17, b= -6[/tex]

hence, the other point is (17, -6).

3. A computer is priced at $65,000 plus value added tax at 15%. What amount does the computer actually cost the customer?

Answers

Answer:

$74,750

Step-by-step explanation:

Given that,

The cost of a computer = $65,000 + value added tax at 15%

We need to find the amount the computer actually cost the customer.

Total cost = Cost of computer + VAT at 15%

[tex]=65000+65000\times \dfrac{15}{100}\\\\=\$74,750[/tex]

So, the computer actually cost the customer is $74,750.

Let sin(2x)-sin(x)=0, where 0 ≤ x < 2pi. What are the possible solutions for x?

Answers

Step-by-step explanation:

sin2x - sinx = 0

2sinxcosx - sinx = 0

(Double Angle Formula)

sinx(2cosx - 1) = 0

Either sinx = 0 or cosx = 1/2.

When sinx = 0,

x = 0 or x = π.

When cosx = 1/2,

x = π/3 or x = 5π/3.

Hence the solutions are

x = 0, x = π/3, x = π or x = 5π/3.

Sam had 1 1-2 m of rope. He cut off 5-8 m and used it for the project. How much does Sam have left

Answers

1 1/2 m and 5/8 meter need to have the same denominator in order to subtract.

1 1/2 is equivalent to 12/8
Now 5/8 and 12/8 have the same denominator so you can subtract.
12/8-5/8= 7/8
7/8 m is left

The residents of cities A, B, C, D and E consume wi-fi routers, with consumption in each city is 150 routers (see the map below). The firm that produces routers must decide how to set-up production. It could set up five factories, dispersed across each city, with each factory producing 150 routers and supplying to its own local city market. In this case, the firm incurs no cost for shipping output. Alternatively, the firm could locate its factory at centrally located city C, and supply routers to the entire region. The single factory in city C must then produce 750 routers, 600 of which are shipped to the cities A, B, D and E for a shipping cost of $6 per router. A ECB D(a) Suppose the average cost of producing a router is AC (Q) = 1500/Q, where Q is the number of routers produced in a factory. Calculate AC with Q = 150 and Q = 750, respectively. Note and explain how this production process exhibit economies of scale. (b) Based on the AC function from part (a), find the optimal arrangement of production for the firm (one central factory or five dispersed factories). The optimal arrangement minimizes total cost for the firm, where total cost is the sum of production cost and shipping cost. Clearly write down all your calculations. (c) Now suppose the average cost of producing a router is AC = 14000/(Q+1250). Now, repeat the calculation of AC with Q = 150 and Q = 750. (d) Based on the AC function from part (c), now repeat your calculations to find the cost-minimizing arrangement of production in the case. (e) Explain intuitively the difference is results between responses to part (b) and (d). (f) Suppose now production costs are those given in part (a) but let shipping cost per router be given by t (in the preceding discussion, we had t = 6, now we assume we dont know the cost of shipping). What value of t would make the two arrangements for production (centralized versus separate factories) equivalent in terms of cost? i.e. what value of t would make the firm indifferent between a centralized versus a dispersed set-up?
