Aki's Bicycle Designs has determined that when x hundred bicycles are built, the average cost per bicycle is given by C(x)equa

Alenkinab [10]

Answer:

20 Bicycles

Step-by-step explanation:

The function for the average cost,C(x) [in hundred of dollars] per bicycle whenever x hundred bicycles are built is given as:

$C(x)=0.5x^2-0.2x+6.756$

The minimum value of C occurs at the axis of symmetry.

Axis of Symmetry, $x=-\frac{b}{2a}$

Comparing with the standard form of a quadratic equation $ax^2+bx+c=0$

a=0.5, b=-0.2

$x=-\frac{(-0.2)}{2*0.5}\\x=0.2$

x=0.2 Hundreds =0.2 X 100 =20

When Aki's Bicycle Designs produces 20 Bicycles, the cost is minimized.

How to solve 2x^2 - 4x = 3

zhenek [66]

Answer:

1 ± i(1/2)√2

Step-by-step explanation:

Write this quadratic in standard form: subtract 3 from both sides. This results in 2x^2 - 4x - 3 = 0. Let's apply the quadratic formula. The coefficients of the x terms are 2, -4 and -3, so the discriminant is (-4)^2 - 4(2)(-3), or 16 - 24 = -8.

Following the format of the quadratic formula, we get

-(-4) ±i2√8 4 ±i2√2

x = ----------------- = --------------- = 1 ± i(1/2)√2
