Answer:

The value of x is 16

Step-by-step explanation:

In the right triangle of the length of the hypotenuse c and the lengths of two legs a and b

  • a² + b² = c² ⇒ Pythagoras Theorem

In the given figure

∵ The right triangle has two legs of lengths 8√2, 8√2

∴ a = 8√2 and b = 8√2

∵ It has a hypotenuse of length x

∴ c = x

→ Substitute them in the rule above

∵ (8√2)² + (8√2)² = x²

∵ (8√2)² = (8)²(√2)² = (64)(2) = 128

∴ 128 + 128 = x²

∴ 256 = x²

→ Take a square root for both sides

∵ √256 = √(x)²

→ The root will cancel power 2 of x

∴ 16 = x

∴ The value of x is 16

Answer:

The equivalent functions are;

g(x) = 3^{-2 \cdot x }

g(x)  = 9^{-x}

g(x) =   \left (\dfrac{1}{9} \right )^x

Step-by-step explanation:

The given function is f(x) = (1/3)^(2·x)

f(x) = \dfrac{1}{3} ^{2 \cdot x}

The given  function can be simplified as follows;

f(x) = \dfrac{1}{3} ^{2 \cdot x} = 3^{-1 \cdot2 \cdot x } = 3^{-2 \cdot x } = g(x)

∴ f(x) = \dfrac{1}{3} ^{2 \cdot x} ≡  g(x) = 3^{-2 \cdot x }

2) The given  function can also be simplified as follows;

f(x) = \dfrac{1}{3} ^{2 \cdot x} =  \left (\dfrac{1}{3} ^2\right )^x = \left (\dfrac{1}{9} \right )^x = (9^{-1}) ^x} = 9^{-1 \times x} = 9^{-x} = g(x)

∴ f(x) = \dfrac{1}{3} ^{2 \cdot x} ≡ g(x)  = 9^{-x}

3) The given  function can also be simplified as follows;

f(x) = \dfrac{1}{3} ^{2 \cdot x} =  \left (\dfrac{1}{3} ^2\right )^x = \left (\dfrac{1}{9} \right )^x = g(x)

∴ f(x) = \dfrac{1}{3} ^{2 \cdot x} ≡ g(x) =   \left (\dfrac{1}{9} \right )^x
