Simplify (2/9)^3<br> A.6/9<br> B.8/729<br> C.2/720

saw5 [17]

<u>Answer:</u>

$\frac{8}{729}$

<u>Explanation:</u>

Before we begin, remember that:

( $\frac{a}{b}$ )ⁿ = $\frac{a^n}{b^n}$

This means that power is distributed in case of division

The given is:

$(\frac{2}{9} )^3$

Applying the above rule, we would get:

$(\frac{2}{9} )^3$ = $\frac{2^3}{9^3} = \frac{2*2*2}{9*9*9} = \frac{8}{729}$

Hope this helps :)

$\frac{2 |x - 3| }{5} = 6 \\$

$5 \times \frac{2 |x - 3| }{5} = 5 \times 6 \\$

$2 |x - 3| = 30$

$\frac{2 |x - 3| }{2} = \frac{30}{2} \\$

$|x - 3| = 15$

$x - 3 = 15$

$x - 3 + 3 = 15 + 3$

$x = 18$

$x - 3 = - 15$

$x - 3 + 3 = - 15 + 3$

$x = - 12$

A 2000 kg car, initially at rest, is accelerated along a horizontal roadway at 3 m/s2. What is the average power required to bri

FromTheMoon [43]

Answer:

Power = 120000 watts

Step-by-step explanation:

mass = 2000kg

acceleration = 3m/s²

velocity = 20m/s

Force = mass x acceleration

Force = 2000 x 3 = 6000 Newton

Power = Force x velocity

Power = 6000 x 20 = 120000 watts

Since 1000 watts = 1kilo-watts

Power = 120000 watts or 120 kilo-watts
