The sum of 8n^2-3n+10 and -3n^2 -6n-7 is
EastWind [94]

8n^2-3n+10 + -3n^2-6n-7

8n^2 + -3n^2 = 5n^2

-3n + -6n = -9n

10 + -7 = 3

Put them all together and you get 5n^2-9n+3

I tried to space them out so that it makes more sense.

Find a formula for the inverse.
LUCKY_DIMON [66]

f(x) = 6x

To find the inverse, replace f(x) with Y:

y = 6x

Now switch the variables:

x = 6y

Solve for Y by dividing both sides by 6:

y = x/6

Now replace y with f^-1 (x):

f^-1 (x) = x/6

Given that weekly demand curve of a local wine producer is p = 50 − 0.1q, and that
rusak2 [61]

Answer:

Z(p) = -10p² + 600p - 6500

Step-by-step explanation:

Demand curve <em>p</em> = 50 - 0.1 <em>q</em>

Total cost function <em>C</em>(<em>q</em>) = 1500 + 10q

where q is the number of bottles produced each day and p is the selling prices per bottle.

Now, <em>p</em> = 50 - 0.1 <em>q</em>

o.1 <em>q = </em>50 <em>- p</em>

<em>q = </em>500 - 10<em>p</em>

Revenue = price × quantity =<em> p × q</em>

= <em>p</em> ( 500 - 10<em>p</em>)

= 500<em> p</em> - 10<em>p²</em>

Profit = total revenue - total cost

Let Profit be Z since profit is function of price, therefore

<em>Z(p) = pq - C(q)</em>

<em>Z</em> (p)=  500<em> p</em> - 10<em>p</em>² - (1500 + 10<em>q</em>)

Substituting the value of q in above expression,

<em>Z(p) </em>= 500 <em>p</em> - 10<em>p</em>² - ( 1500 + 10 (500 - 10<em>p</em>))

<em>Z(p)</em> = 500<em>p</em> -10<em>p</em>² - 1500 -5000 + 100<em>p</em>

<em>Z(p)</em> = -10<em>p</em>² + 600<em>p</em> - 6500

So, the weekly profit as a function of price p is Z(p) = -10p² + 600p - 6500.
