The cost C in dollars of manufacturing x bicycles at a production plant is given by the function shown below.
Andreas93 [3]

Answer:

  • Minimum 100 bicycles
  • Minimum cost is 13500

Step-by-step explanation:

<u>Given function:</u>

  • C(x) = 3x^2- 600x + 43500

a.

Minimum cost is obtained at vertex.

Vertex is determined by formula x = -b/2a, in standard form of

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

<u>Vertex of the given function is:</u>

  • x = -(-600)/(2*3) = 100

b.

<u>Cost at vertex is:</u>

  • C(100) = 3*100^2 - 600*100 + 43500 = 13500

A variable needs to be eliminated to solve
lesya692 [45]

Answer:

(7, - 7 )

Step-by-step explanation:

- 4x + y = - 35 → (1)

- 2x - y = - 7 → (2)

adding the 2 equations term by term will eliminate the y- term

(- 4x - 2x) + (y - y) = - 35 - 7

- 6x + 0 = - 42

- 6x = - 42 ( divide both sides by - 6 )

x = 7

substitute x = 7 into either of the 2 equations and solve for y

substituting into (1)

- 4(7) + y = - 35

- 28 + y = - 35 ( add 28 to both sides )

y = - 7

solution is (7, - 7 )

Please help me<br> This is analytic geometry
Vlada [557]

Answer:

The coordinates of point B are (-3,-3).

Step-by-step explanation:

Let A(x,y) = (6,-6), C(x,y) = (-6,-2) and \overrightarrow{AB} = \frac{3}{4}\cdot \overrightarrow{AC}, then we have the following formula by vectorial definition of a line segment:

\overrightarrow{AB} = \frac{3}{4}\cdot \overrightarrow{AC}

B(x,y) -A(x,y) = \frac{3}{4}\cdot [C(x,y)-A(x,y)]

B(x,y) = \frac{3}{4}\cdot C(x,y) +\frac{1}{4}\cdot A(x,y)

B(x,y) = \frac{3}{4}\cdot (-6,-2)+\frac{1}{4}\cdot (6,-6)

B(x,y) = (-3, -3)
