Answer:

Step-by-step explanation:

y=mx+b

m=dy/dx=(0-8)/(4-0)=-8/4=-2

y=-2x+b, using point (4,0)

0=-2(4)+b

b=8

y=-2x+8

Find the equation of the line tangent to the graph of f(x)=(lnx)^(4)at x=10

Diano4ka-milaya [45]

Hello,

Step-by-step explanation:

$f(x) = ln(x) {}^{4}$

$(ln(u)') = \frac{u'}{u}$

$f'(x) = \frac{4ln {}^{} (x) {}^{3} }{x}$

$f'(10) = \frac{4ln {}^{} (10) {}^{3} }{10} = \frac{12ln(x)}{x}$

$f(10) = ln(10) {}^{4}$

$y = \frac{12ln(x)}{x} (x - 10) + 4ln(10)$

$y = f'(a)(x - a) + f(a)$

Sunset, inc., has a book value of equity of $14,865. long-term debt is $8,675. net working capital, other than cash, is $2,315.

juin [17]

Balance sheet equation states that:

Assets, A = Liabilities, L + Equity, E => A=L+E

In the current case,
L = Long term debt + Current liabilities = $8,675+$1,865 = $10,540
E = $14,865

Therefore,
A = 14,865 +10,540 = $25,405

Now,
Current assets (excluding cash) = current liabilities+Net working capital, other than cash = $1,865+$2,315 = $4,180

Additionally,
A = Fixed assets+Current assets (excluding cash) + Cash

Therefore,
Cash = 25,405-20,660-4,180 = $565

djyliett [7]

Answer:

The probability is 0.0069

Step-by-step explanation:

First thing to do here is to calculate the z-score

Mathematically;

z-score = (x-mean)/SD/√(n)

where x = 9.1 , mean = 8.4 , SD = 1.8 and n = 40

Plugging these values into the z-score equation, we have;

z-score = (9.1-8.4)/1.8/√(40) = 0.7/1.8/6.325 = 0.0615

Now, we check the standard normal table for P(z > 2.46) = 0.0069
