A skateboard manufacturer finds that the cost $C of making x skateboards per day can be modelled by the function C(x) = ax
2+bx+c

If 50 skateboards are made in a day, the cost of production is $1544.
The manufacturer noticed that making 12 skateboards in a day minimizes the cost of
production to $100.
a) Write C(x) in the vertex form. Hence, find the values of a, b and c.
b) What is the cost of production if no skateboards are made in a day?
c) What is the number of skateboards made in a day for a cost of production of $116?
d) What is the number of skateboards made in a day for a cost of production of at most $116?

the barter

step-by-step explanation:

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
