Answer:

b=(13/4, -27/4, -4)

Step-by-step explanation:

A.x=b

x=(a, b, c)

a   - b + 2c = 2

3a + b +  0 = 3

0  + 0 +  c = -4

solving this system

c=-4

a-b=10, 3a+b=3

a=10+b, 3(10+b)+b=3

b=-27/4

a=10-27/4

a=13/4

Evaluate the following using<br> powers of ten rules.<br> 104)1.042
Alinara [238K]

Answer:

0.0001042

Step-by-step explanation:

Power of tens rule states that if the denominator of a fraction has the positive power of 10, decimal in the numerator will be shifted to the left by the same number of places as exponent.

10⁴) 1.042 = \frac{1.042}{10^4}

In the denominator of the given fraction, exponent of 10 = +4

So the decimal in numerator will be shifted left by 4 places.

\frac{1.042}{10^4}=0.0001042

Therefore, answer is 0.0001042
