Find the co-ordinates of the vertex of the function y=x²-12x+2 and show your work
nataly862011 [7]

Answer:

(6,-34)

Step-by-step explanation:

You can use the vertex formula to find the x of the vertex and then plugin the x value into the formula to find the y value.

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

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

x = -\frac{-12}{2(1)}

x = 6}

Now plugin 6 into  y=x²-12x+2

y=x²-12x+2

y=6²-12(6)+2

y=36-72+2

y=36-72+2

y = -34

Vertex = (6,-34)

Bikes'R'Us manufactures bikes, which sell for $250. It costs the $180 per bike, plus a startup fee of $3,500. After how many bik
lions [1.4K]

<u>Answer:</u>

The bikes sold at break even by the manufacturer is 50 units

<u>Explanation:</u>

We know that break even point is given by  the following formula,

$\frac{\text { Fixed costs }}{\text { (Price per unit - Variable costs) }}$

We are given startup fee = $3500 which is the fixed cost,

the bikes sell for $250 which is the price per unit and

cost per bike is equal to $180

So substituting these values in the formula we get

= \frac{3500}{(250-180)}

= \frac{3500}{(70)}  = 50

= 50 units which is the number of bikes sold at break even by the manufacturer.

it would depend how much you actually used, but you would take the amount you used  and divide it by the total amount of yarn. so if the yarn was 4m long and you used 2m then it would be 2/4 which is 0.5 which is also 50%, so half the yarn was used.
