[Right Triangles Only] SOHCAHTOA
[Right Triangles Only] cosθ = adjacent over hypotenuse
Inverse Trig

Step-by-step explanation:

Step 1: Define

Identify variables

Angle θ = x°

Adjacent Leg = 43

Hypotenuse = 87

Step 2: Solve for x

Substitute in variables [cosine]: cos(x°) = 43/87
Inverse Trig: x° = cos⁻¹(43/87)
Evaluate: x° = 60.3795
Round: x° ≈ 60.4

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

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:

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

$\delta = 0.24\,\%$

Factorise pls any inappropriate answers will be reported thanks xx

You have to figure out the highest common factor of each set of values:
9a + 21 = 3(3a + 7)
21b - 49 = 7(3b - 7)
54 - 6c = 6(9 - c)
8a + 32b = 8(a + 4b)
4p + 28q + 8r = 4(p + 7q +2r)
84a - 36b -12c = 6(14a - 6b - 2c)
6p + 9q + 15r = 3(2p + 3q + 5r)
18s - 30t + 54u = 6(3s - 5t + 9u)
Hope this helps :)

Suppose a line L has an equation Ax+By+C==0, what is the slope of L if B=0 and A does not equal 0

White raven [17]

If B=0, and A≠0, then
Ax+C=0, or x=-C/A, a constant value.
This signifies L is a vertical line with slope ∞
