( −2 x^3) ^ 3 simplify

densk [106]

Answer:

$-8x^9$

Step-by-step explanation:

We can split up the exponent into multiple products: $(-2x^3)^3=(-2)^3*(x^3)^3$ .

We know that $(-2)^3=(-2)*(-2)*(-2)=-1*-1*-1*2*2*2=-1*8=-8$ .

We also know that $(x^3)^3=x^{3*3}=x^9$ .

So, our answer is $\boxed{-8x^9}$ and we're done!

The graph shows the distance, y, in miles, of a moving motorboat from an island for a certain amount of time, x, in hours:

lisabon 2012 [21]

Answer: The speed of the motorboat is 70 miles per hour

Step-by-step explanation: Subtract the initial distance, 35, from the distance at any given time, then divide the remainder by the hours.

For example, at 2 hours, the distance shown on the graph is 175 miles

Subtract: 175 -35 = 140. Then divide 140/2 = 70

At 4 hours, the distance shown is 315 miles.

Subtract: 315 - 35 = 280. Then divide 280/4 = 70

70 mph is the speed.
