With Quadratic Functions: Application Quick Computing Company produces
calculators. They have found that the
cost, c(x), of making x calculators is a
quadratic function in terms of x.
Complete the function that represents the cost,
C(x), to produce x calculators.
c(x) =
The company also discovered that it
costs $19.50 to produce 3 calculators,
$47.50 to produce 7 calculators, and
$105 to produce 12 calculators.
?

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.

correct answer was 0.5
