Two numbers, if the first one increases by 1, and the second one decreases by 1, then their product increases by 2020. If the first number decreases by 1, and the second one increases by 1, what value does the product decrease?

Answers

Answer:

The product decreases 2022.

Step-by-step explanation:

(x + 1)(y - 1) = xy + 2020

xy - x + y - 1 = xy + 2020

-x + y = 2021

(x - 1)(y + 1) = xy + x - y - 1

+ 2021 = -x + y

----------------------------------

(x - 1)(y + 1) + 2021 = xy - 1

(x - 1)(y + 1) = xy - 2022

The product decreases 2022.

Final answer:

The short run in economics is a period in which some of a firm's inputs are fixed. These fixed inputs can include capital, such as the factory building, which cannot be adjusted quickly in response to changes in economic circumstances. Meanwhile, in the long run, all of a firm's inputs can be changed.

Explanation:

In economics, the short run is referred to as a period wherein some of a firm's inputs are fixed. Notable examples of these fixed inputs can be capital or the factory building, which cannot be increased or decreased instantaneously in response to economic circumstances. This distinguishing characteristicseparates the short run from the long run where, in contrast, firms have the flexibility to change all inputs.

Examples

For instance, consider a bakery production. In the short run, the bakery cannot immediately expand its premises or decrease the size of its building if the demand changes. The equipment can't be heightened, the building is fixed and it can't be altered. Here, the bakery can increase production by hiring more employees or extending their hours which are known as variable inputs but cannot change its fixed inputs like the size of the building or equipment.

A cell site is a site where electronic communications equipment is placed in a cellular network for the use of mobile phones. The numbers y of cell sites from 1985 through 2011 can be modeled byy = 269573/1+985e^-0.308t where t represents the year, with t = 5 corresponding to 1985. Use the model to find the numbers of cell sites in the years 1998, 2003, and 2006.

Answers

Answer:

(a) 3178

(b) 14231

Step-by-step explanation:

Given

$y = (269573)/(1+985e^(-0.308t))$

Solving (a): Year = 1998

1998 means t = 8 i.e. 1998 - 1990

So:

$y = (269573)/(1+985e^(-0.308*8))$

$y = (269573)/(1+985e^(-2.464))$

$y = (269573)/(1+985*0.08509)$

$y = (269573)/(84.81365)$

$y = 3178$ --- approximated

Solving (b): Year = 2003

2003 means t = 13 i.e. 2003 - 1990

So:

$y = (269573)/(1+985e^(-0.308*13))$

$y = (269573)/(1+985e^(-4.004))$

$y = (269573)/(1+985*0.01824)$

$y = (269573)/(18.9664)$

$y = 14213$ --- approximated

Solving (c): Year = 2006

2006 means t = 16 i.e. 2006 - 1990

So:

$y = (269573)/(1+985e^(-0.308*16))$

$y = (269573)/(1+985e^(-4.928))$

$y = (269573)/(1+985*0.00724)$

$y = (269573)/(8.1314)$

$y = 33152$ --- approximated
