The surface area of a cube is 96 square feet. Find the volume of the cube.
Tamiku [17]
<span>cube has six identical walls

96ft</span>²<span> : 6 = 6 ft</span>²<span>  - </span>one wall surface

<span>pattern on the surface of the cube
</span>A = a²
a - <span>the edge of the cube

A = a</span>²    ⇔ a=√A
                  a = √(16ft)² = 4ft
V = volume
V = a³
V = (4ft)³ = 64 ft³

A car approaches a stop sign going 10 m/s before coming to a stop. If it takes 5 seconds to
Levart [38]

Answer:

The acceleration is: a = -2 m/s²

The negative sign indicates that velocity is decreasing with time.

Step-by-step explanation:

Given

  • Initial velocity u = 10 m/s
  • Final velocity v = 0
  • Time taken t = 5 seconds

To determine

Acceleration a = ?

Using the formula to determine the acceleration

a = (v - u) / t

substituting u = 10 m/s, v = 0 and t = 5

a = (0 - 10) / 5

a = -10 / 5

a = -2 m/s²

Thus,

The acceleration is: a = -2 m/s²

The negative sign indicates that velocity is decreasing with time.

10 points?...1) must be quick to answer,2) must be reasonable answer,3) Show explanation for your answer
Ilia_Sergeevich [38]
Your answer is
{x}^{2}  \div   {2} {z}^{9}
because the numbers raised to negative powers must be flipped over the divisor to become positive. Then, when multiplying 2 and z, you add their exponents.
