Given a point (4,80) and a slope, m = 60, these can be used to formulate the equation of the graph. Using the point-slope formula:

y - y1 = m(x - x1)

y - 80 = 60(x - 4)

y - 80 = 60x - 240

y = 60x -160

Taking the x and y-intercepts:

At y = 0

0 = 60x - 160

x = 2.7

At x = 0

y = 60(0) - 160

y = -160

There is a graph of a line that has a y intercept that is negative $160 million and an x intercept that is 2.7 years.

Sveta_85 [38]

Answer:

42

Step-by-step explanation:

there are a possible 6 combinations for a sum of 7:

1,6

6,1

2,5

5,2

3,4

4,3

so we can create this proportion:

7/36 = n/216

n = # times to roll a sum of 7 out of 216

now cross-multiply:

36n = 1512

n = 1512/36

n = 42

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\,\%
