Suppose the cost of publishing x books is C(x) = 10000 + 25<img src="https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D" id="TexFormula1" ti

dusya [7]

Answer:

$\frac{dC}{dQ} \approx 1.25$ , $C(101)-C(100) = 1.247$ , $\delta = 0.24\,\%$

Step-by-step explanation:

The marginal cost function is:

$\frac{dC}{dQ} = 12.5\cdot x^{-\frac{1}{2} }$

The marginal cost for 100 books is:

$\frac{dC}{dQ} \approx 1.25$

The difference is:

$C(101)-C(100) = 25\cdot (101^{\frac{1}{2} }-100^{\frac{1}{2} })$

$C(101)-C(100) = 1.247$

The relative error is:

$\delta = \frac{|1.25-1.247|}{1.25}\times 100\,\%$

$\delta = 0.24\,\%$

How do i determine the value of sine

Margaret [11]

Well, you can do that by many ways like:
If you have value of B & P or B & H, you can find the other one by the formula,
H² = P²+B²
Then, you can easily calculate the value of sine by putting P/H

Hope this helps!

The temperature of a hot steak starts at 140f and decreases at 5f per minute what will the temperature of this steak after a cer

irina1246 [14]

Answer:

T(m) = (140 - 5m)

Step-by-step explanation:

Given that :

Initial temperature, a = 140 F

Rate of decrease = 5 F per minute

Given a certain Number of minutes, m

Temperature, T after m minutes ;

Using the formula :

Final temperature = Initial temperature - 5*number of minutes)

T(m) = (140 - 5m)

Given that ; m = 10

T(10) = 140 - 5(10)

T(10) = 140 - 50

T(10) = 90 F

Triangle ABC is being dilated with the center of dilation at the origin. The image of C, point C' has coordinates of (7.2, 3.6).

MAXImum [283]

General Idea:

When we are given a point P(x, y) centered at origin with a scale factor of k, then the dilated point will be given by P' (kx, ky)

Applying the concept:

In the diagram given, the coordinate of C is (6, 3). Triangle ABC is being dilated with the center of dilation at the origin. The image of C, point C' has coordinates of (7.2, 3.6).

If C (x, y) centered at origin with a scale factor of k, then the dilated point will be given by C' (kx, ky)

We know $x = 6$ & $kx = 7.2$
