Answer:

( 8x²)³ = 512 $x^{6}$ .

Step-by-step explanation:

Given : ( 8x²)³.

To find : simplification.

Solution : We have given that ( 8x²)³.

We can write it (8)³ * (x²)³.

⇒ 512 $x^{6}$ .

Therefore, ( 8x²)³ = 512 $x^{6}$ .

If a circle has radius 10 cm, find the length of the arc subtended by a central angle of 36°.

snow_lady [41]

Angle = 36 degrees = $\frac{\pi}{180} \times 36$ = $\pi / 5$

now, radius = 10 cm

so arc = radius x angle = 10 x pi/5 = 2pi = 6.28 cm

A rocket is launched from atop a 75 foot cliff with an initial vertical velocity of 107 feet per second. The height of the rocke

satela [25.4K]

The distance of the rocket hitting the ground is 715.56 feet in 6.68 seconds

<u>Explanation:</u>

Given:

Height, h = 75 foot

Initial velocity, u = 107 foot/sec

Equation:

h = -16t² + 107t + 75

Substituting the equation:

75 = -16t² + 107t + 75

0 = -16t² + 107t

16t² = 107t

t = 6.6875s

We know:

Distance = speed X time

d = 107 f/s X 6.6875s

d = 715.56 foot

Therefore, the distance of the rocket hitting the ground is 715.56 feet in 6.68 seconds
