F ( x ) = k * x²
f ( 4 ) = 96
96 = k * 4²
96 = 16 k
k = 96 : 16
k = 6
f ( 2 ) = 6 * 2² = 6 * 4 = 24

elena-s [515]

Answer:

  a. 37

  b. 25

  c. 226

Step-by-step explanation:

Place value has the same meaning in any other number base that it has in base 10. Using expanded form is one way to do the required base conversion.

a. 122₅ = 1×5² +2×5¹ +2×5⁰

   = 25 +10 +2 = 37

__

b. 11001₂ = 1×2⁴ +1×2³ +0×2² +0×2¹ +1×2⁰

   = 16 +8 + 1 = 25

__

c. 16T₁₂ = 1×12² +6×12¹ +10×12⁰

   = 144 +72 +10 = 226
