To determine the correct ordered pairs which will agree with the function, we can substitute values to the function and see whether it agree with each other. We do as follows:

<span>(0,1)
</span><span> f(x)=128(0.5)^0
</span><span> f(x)=128
</span><span>
(1,64)
</span><span> f(x)=128(0.5)^1
</span>f(x) = 64  <--------CORRECT ANSWER<span>

(3,16)
</span><span> f(x)=128(0.5)^3
f(x) = 16 <--------CORRECT ANSWER
</span><span>
(8,0.5)
</span><span> f(x)=128(0.5)^8
f(x) = 1/2

Total surface area of a cube is 1014cm^2. It's volume will be :
Karolina [17]

Answer:

Option A (2197 cm³)

Step-by-step explanation:

For a cube with length of each side "a" , it's

  • Total Surface Area = 6a²
  • Volume = a³

_____________________________________________

According to the question ,

Total Surface Area = 1014 cm²

Let the length of each side of cube be 'a'.

Using the formula ,

6a^{2} =1014

=> a^{2} =\frac{1014}{6} = 169

=> a = \sqrt{169} = +13 \: or  -13

But length can't be negative . So , length of each side = 13 cm

∴ Volume of cube = 13³ = 2197 cm³
