Answer:

answer would be the first choice.

Step-by-step explanation:

you would need to factor out x from the expression, then factor out -3 from the expression, factor the expression using a^2-B^2=(a-b)(a+b), afterwards you factor out the 4 from the expression, and then the 3x. Next you would factor out 2x+1, reduce the expression with x-5, reduce the numbers with the greatest common divisor 2, you then reduce the expression with x-3, multiply the fractions, distribute 2 through the parenthesis, distribute the 3x through the parenthesis, and that should be all.

The Pear company sells pPhones. The cost to manufacture x pPhones is C ( x ) = - 21 x² + 67000 x + 20006 dollars (this includes

Answer:

Company should produce 8000 phones for the maximum profit.

Step-by-step explanation:

Function representing cost to the manufacturer is,

C(x) = -21x²+ 67000x + 20006

Function that represents the revenue generated is,

R(x) = -28x² + 179000x

Function representing profit to the company,

Profit = Revenue generated - Cost price

= -28x² + 179000x - (- 21x² + 67000x + 20006)

= -28x² + 21x² + 179000x - 67000x - 20006

P(x) = -7x² + 112000x - 20006

Since this function is a quadratic function therefore, the maximum price generated will be for

$x=-\frac{b}{2a}$

From the given quadratic function, a = (-7), b = 112000 and c = -20006

Therefore, for $x=-\frac{112000}{2\times (-7)}$

Or x = 8000 the profit to the company will be maximum.

That means pear company should produce 8000 phones for the maximum profit.

You need slope and y- intercept. It is a negative slope because the line is going down from left to right. Count rise over run.

M = - 4/6 = -2/3
If the line continued to the y axis it would cross at 10.
y = -2/3x + 10

The table summarizes the result of spinning the spinner shown.

weqwewe [10]

Hello!

Experimental probability is the probability in relation to the data that has been collected. In this example, adding up the times spun we get 18 times spun. Where red was spun 6 times, this is 1/3 of what was done.

Our answer is B) 1/3.

Hope this helped!
