What Is the product? 4n/4n-4*n-1/n+1

Mathematics
1 answer:
Serjik [45]3 years ago
7 0

Answer:

n/(n+1) . . . . n ≠ 1

Step-by-step explanation:

As written, there is no product. There is ony the sum ...

4\dfrac{n}{4}-4n-\dfrac{1}{n}+1

With appropriate parentheses, this becomes the product of rational functions ...

... (4n)/(4n-4)·(n-1)/(n+1)

=\dfrac{4n(n-1)}{4(n-1)(n+1)}=\dfrac{n}{n+1}

_____

At n=1, the product has a "hole" where the denominator of the original expression is zero, so the expression is undefined. Hence the domain of the product must be restricted to n≠1 (as well as n≠-1).

What is the slope of a line perpendicular to a line that's passes through (3,8) and (1,-4)?
Serjik [45]

Answer:

-1/6

Step-by-step explanation:

First find the slope of the line through the points

m = (y2-y1)/(x2-x1)

    = (-4-8)/(1-3)

     = -12/-2

      =6

Now we need to find the slope of the line that is perpendicular

Perpendicular lines multiply to -1

6 * mp = -1

mp = -1/6

Suppose demand d for a company's product at cost x is predicted by the
11111nata11111 [884]

Answer:

0.36x ² + 815.04x + 11,340

Step-by-step explanation:

Revenue = price × quantity

p(x) = x+14

d(x) = 0.36x + 810

Revenue = price × quantity

= (x + 14) * (0.36x + 810)

= 0.36x² + 810x + 5.04x + 11,340

= 0.36x ² + 815.04x + 11,340

Company's revenue = 0.36x ² + 815.04x + 11,340
