30 divided by 5 is 6, so the other term is (x+6). (x+5)(x+6) becomes x^2+11x+30, so k is equal to 11.

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:

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

$\delta = 0.24\,\%$

What basic trigonometric identity would you use to verify that sin x con x tan x= 1-cos^2x?

Blababa [14]

Answer:

The answer is (a) ⇒ tanx = sinx/cosx

Step-by-step explanation:

∵ (sinx)(cosx)(tanx) = (sinx)(cosx)(sinx/cosx) = sin²x

∵ sin²x = 1-cos²x

∴ L.H.S = R.H.S

∴ (sinx)(cosx)(tanx) = 1 - cos²x

blagie [28]

Answer: 3/4 of an hour left.

Step-by-step explanation:

Step 1: 2 hours = 4/4 +4/4

Step 2: 4/4 - 2/4 = 2/4

Step 3: 4/4 - 3/4 = 1/4

Step 4: 2/4 + 1/4= 3/4
