DiKsa [7]

we know that

Jamie has 7/10 of a pound of chicken to cook for dinner for three people

so

<u>Step 1</u>

Divide 7/10 by 3

\frac{(7/10)}{3}   =\frac{7}{10*3} =  \frac{7}{30}\ lb

therefore

<u>the answer is</u>

Each person get \frac{7}{30}\ lb of chicken

A vehicle factory manufactures cars. The unit cost C(the cost in dollars to make each car) depends on the number of cars made. I
DedPeter [7]

Answer:

300 cars must be made to minimize the unit cost

Step-by-step explanation:

Vertex of a quadratic function:

Suppose we have a quadratic function in the following format:

f(x) = ax^{2} + bx + c

It's vertex is the point (x_{v}, y_{v})

In which

x_{v} = -\frac{b}{2a}

y_{v} = -\frac{\Delta}{4a}

Where

\Delta = b^2-4ac

If a>0, the vertex is a minimum point, that is, the minimum value happens at x_{v}, and it's value is y_{v}.

The cost of producing x cars is given by:

C(x) = 0.7x^2 - 420x + 81610

So a quadratic equation with a = 0.7, b = -420, c = 81610

How many cars must be made to minimize the unit cost?

This is the xvalue of the vertex. So

x_v = -\frac{b}{2a} = -\frac{-420}{2*0.7} = \frac{420}{1.4} = 300

300 cars must be made to minimize the unit cost
