The straight line y = x -1 is shown figure  

To plot straight-line graphs we need to take values of x and y values to make a value table and to work out the graph.

Take x values as -1, 0, 1, etc. to make our work easy and clearer, and from that find the values of y.

After calculating the coordinates, use the resultant points to plot the line as a graph.  

Here we have a line

y = x -1  

To sketch the graph we need to make a value table as given below

First take x values as, -1,  0, 1 from that find the values of y  

At  x = -1 => y = -1 - 1 = -2

At  x = 0 => y = 0 - 1 = -1

At  x = 1 =>  y = 1 - 1 = 0  

From the above calculations, the value table is

        x   -1   0   1

        y   -2  -1  0      

Use the above value and Sketch the graph

The operating income of Division B will increase by $640,000

Given that: Division B incurs variable costs of $10 per unit and  a transfer price of $18 per unit is established between the two divisions and 80,000 units of materials are transferred to Division A

This cost of production by division B is:

cost = $10 × 80,000 = $800,000

Division B uses a transfer price of $18 per unit. That is:

Selling price = $18  × 80,000 = $1,440,000

Operating income increase = Selling price - cost

Operating income increase = $1,440,000 - $800,000 = $640,000

Therefore, Division B's operating income increase will be $640,000

The number of dogs do they need to walk in order to pay for the box of treats is 4

The function that representing the profit is

y = 3x - 5

The slope intercept form is

y = mx + b

Where m is the slope of the line

b is the y intercept

Here the cost for buying a box of treat = $5

Substitute the value in the function and find the number of dog that they need to walk

5 = 3x - 5

3x = 5 + 5

3x = 10

x = 10 / 3

x = 3.33

Answer: y > -3/4x + 2

Step-by-step explanation:

The calculation of the ending inventory and the cost of goods sold using FIFO and LIFO methods for ABC Inc. is as follows:

                                          FIFO          LIFO

Ending inventory          $10,250     $12,800

Cost of goods sold       $17,000     $14,450

FIFO, which means First-in, First-out, computes the cost of goods sold based on the assumption that the physical flow of goods sold depends on the earlier inventory in stock.

FIFO can be applied under both the perpetual and periodic inventory systems, unlike LIFO.

LIFO means Last-in, First-out, and as a cost flow assumption assigns the cost of goods sold based on the latest inventory purchases.

LIFO cannot be used under the perpetual inventory system.

Date        Activities                       Units     Unit Rate      Total Cost

April 1     Beginning inventory       220          $50             $11,000

April 5    Purchases                        100          $60                6,000

April 10   Purchases                         50          $45                2,250

April 16   Sales                              -300          $80

April 25  Sales                                -20          $95

April 30  Purchases                      200          $40                8,000

Total                                              570                             $27,250

Units sold                                      320

Ending inventory                         250

FIFO:

Ending Inventory = $10,250 (200 x $40 + 50 x $45)

Cost of goods sold = $17,000 ($27,250 - $10,250)

LIFO:

Ending Inventory = $12,800 (220 x $50 + 30 x $60)

Cost of goods sold = $14,450 ($27,250 - $12,800)

The probability that the number of U.S. adults who favor the use of unmanned drones by police agencies is​;

(a) exactly​ three = 0.1314

(b) at least​ four = 0.7953

(c) less than eight = 0.93382

The binomial probability distribution is the probability of exactly x successes on n repeated trials, with p probability. The formula is;

P(X = x) = ⁿCₓ * pˣ * (1 - p)^(n - x)

We are given;

p = 41% = 0.41

n = 12

Thus;

1) The probability that the number of U.S. adults who favor the use of unmanned drones by police agencies is​ exactly​ three;

P(3) = ¹²C₃ * 0.41³ * (1 - 0.41)^(12 - 3)

P(3) = 0.1314

2) The probability that the number of U.S. adults who favor the use of unmanned drones by police agencies is at least​ four;

P(x ≥ 4) = P(X = 4) + P(X = 5) + P(X = 6) + P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10) + P(X = 11) + P(X = 12)

P(x ≥ 4) = 0.7953

3) The probability that the number of U.S. adults who favor the use of unmanned drones by police agencies is less than eight using binomial probability calculator is;

P(X < 8) = 0.93382

The expected change in the dividend of a 6% preferred stock is $75.

Given that, the required rate of return drops instantly from 8% to 6%.

A return, also known as a financial return, in its simplest terms, is the money made or lost on an investment over some period of time.

The value of preferred stock = $100

Annual dividend = 100 × 6% = $6

Price of preferred stock when required return is 8% = Annual dividend / Required rate of return

= 6/8%

= 6 ×100/8

= $75

Therefore, the expected change in the dividend of a 6% preferred stock is $75.

The equation that can be used to find the number of years after 2012 that the population will triple to 300,000 is option B  t = ln(3) / 0.05

Given,

The population of a city can be modeled using the formula P=100,000e^(0.05t)

t is the number of years after 2012

P is the population of the city

We have to find the equation that can be used to find the number of years after 2012 that the population will triple to 300,000.

Here,

Substitute 300000 in for P and solve for t

300000=100000e^0.05t

Divide both sides by 100000:

We get,

3 = e^0.05t

Multiply both sides by the natural log (ln)

Then,

ln(3) = 0.05t

Now, divide 0.05 on both sides to get t by its self

t = ln(3) / 0.05

Therefore,

The equation that can be used to find the number of years after 2012 that the population will triple to 300,000 is option B  t = ln(3) / 0.05

I assume our task is to find that point of time, when it reaches the highest point.

and the function is

h(t) = -16t² + 96t + 112

well, a maximum or minimum of a curve (function) is found as a zero solution of the first derivative of the function.

given the nature of the function, the extreme point has to be a maximum (the firecracker goes up and then down again).

h'(t) = -32t + 96

we are looking for the zero :

0 = -32t + 96

32t = 96

t = 3 seconds

so, after 3 seconds, the firecracker reaches its highest point, which is at

-16×3² + 96×3 + 112 = -16×9 + 96×3 + 112 =
