The cost of producing x bags of dog food is given by C(x) = 800 + 400 + 10x - x where 0 SX 55000. Find the marginal-cost functio

nikdorinn [45]

Answer:

The marginal-cost function is;

c'(x)= (20x-1)/(2√(400 + 10x² - x))

Completed question;

The cost of producing x bags of dog food is given by C(x) = 800 + √(400 + 10x² - x) where 0≤x≤55000. Find the marginal-cost function.

The marginal-cost function is c'(x)=

(Use integers or fractions for any numbers in the expression.)

Step-by-step explanation:

The marginal-cost function is c'(x)= = dC(x)/dx

Where;

C(x) = 800 + √(400 + 10x² - x)

c'(x) = d(800 + √(400 + 10x² - x) )/dx

Using function of function rule of differentiation or chain rule;

c'(x) = (20x-1)×(1/2√(400 + 10x² - x))

c'(x) = (20x-1)/(2√(400 + 10x² - x))

The marginal-cost function is;

c'(x)= (20x-1)/(2√(400 + 10x² - x))

Answer:

Therefore,

$BC=y=10.61\ units\\\\AC=x=8.6\ units$

Step-by-step explanation:

Consider a Δ ABC with

m∠ B= 45°

m∠ C = 90°

AB = c = 15 cm

To Find:

BC = a = y ?

Solution:

Triangle sum property:

In a Triangle sum of the measures of all the angles of a triangle is 180°.

$\angle A+\angle B+\angle C=180\\\\\angle B +35+90+=180\\\therefore m\angle A =180-125=55\°$

We know in a Triangle Sine Rule Says that,

In Δ ABC,

$\frac{a}{\sin A}= \frac{b}{\sin B}= \frac{c}{\sin C}$

substituting the given values we get

$\frac{a}{\sin 55}= \frac{b}{\sin 35}= \frac{15}{\sin 90}$

∴ $\frac{y}{\sin 55}= \frac{15}{1}\\\\y=\sin 55\times 15\\\\y=10.606\\\therefore BC = y = 10.61\ units$

Similarly for 'x',

$\frac{x}{\sin 35}= \frac{15}{1}$

$\therefore x =\sin 35\times 15\\\therefore x =0.5735\times 15\\\therefore x =8.6\\$

Therefore,

$BC=y=10.61\ units\\\\AC=x=8.6\ units$
