The side length of a square ice cube is claimed to be 1.0 inches, correct to within 0.001 inch. Use linear approximation to esti
Olenka [21]

Answer:

0.012

Step-by-step explanation:

Linear approximation says that,

f(x) \approx f(x_o)+f'(x_o)(x-x_o)

For a cube the surface area is 6x^2.

So the side is 1.0 inch in, the surface area is =6\times1^2 = 6 square inches.  

In Linear approximation means you ignore the term x_o^2 , if x_o is a small number, because then x_o^2 will be a very smalle number and that does not contribute much to the error.  

So the surface area is approximately,

6x^2=6x_o^2+12x_o(x-x_o)

So here, x=1.001, x_o=0.001

The error in the area is approximately,

12 \times 0.001=0.012

So the error is 0.012.

9(n+3)=7n-3 Help Me Find "X"
Y_Kistochka [10]
9(n+3)=7n-3

1) distribute 9 into (n+3)

9n+27=7n-3

2) subtract 7n on both sides

2n+27=-3

3) subtract 27 on both sides

2n=-30

4) divide by 2

n=-15

A faulty communication line for digital signals flips 25% of the 0's to 1's and 1/3 of the 1's to 0's. if 40% of a particular fi
sveta [45]

I find it helpful to put the given information into a chart. It shows the probability of receiving a 0 is 50%, and that when a 0 is received, 30% of the time a 0 was sent and 20% of the time a 1 was sent.

Hence ...

P(sent 0 | received 0) = P(sent 0 & received 0) / P(received 0)

P(sent 0 | received 0) = 0.30/0.50 = 3/5 = 0.60
