A small company that manufactures snowboards uses the relation P=162x-81x^2 to model its profit. In this model, x represents the
Snowcat [4.5K]

From the quadratic equation, it is found that the 2000 snowboards must be produced for the company to break even.

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

The profit of producing x thousand snowboards is given by:

P(x) = 162x - 81x^2

The break even point is the value of <u>x for which P(x) = 0</u>, thus:

162x - 81x^2 = 0

81x^2 - 162x = 0

81x(x - 2) = 0

That has two solutions:

81x = 0 \rightarrow x = 0

x - 2 = 0 \rightarrow x = 2

x is in thousands, and we want the non-zero solution, thus 2000 snowboards must be produced for the company to break even.

1) Given the area of a Football field (57,600 sqft), and the dimensions of a
Neporo4naja [7]

Answer:

Option (d).

Step-by-step explanation:

Given that,

The area of a Football field is 57,600 sqft

The dimensions of Basketball court is 84ft x 50ft

We need to find what fraction of the football crowd would fit  on the court. Taking ratio of the area of basket ball court to the football court as follows :

R=\dfrac{84\times 50}{57,600}\\\\R=\dfrac{7}{96}\ =\ 0.0729

It is less than a tenth. Hence, the correct option is (d).

Hi there!

c=74

<u><em>Equation:</em></u>

26+c=100

c+26=100

100-c=26

100=c+26

100=26+c

<u><em>1.Find the meaning:</em></u>

so 26 contacts and then the total would be 100 which would be 26+c=100...

<em><u>2.Subtract the two terms:</u></em>

<em><u /></em>100-26=74<em><u /></em>

Therefore, c=74
