<u>Step 1: Define</u>
f(x) = 1/2(4)ˣ
f(3) is x = 3
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(3) = 1/2(4)³
- Exponents: f(3) = 1/2(64)
- Multiply: f(3) = 32

Answer:
71.25%.
Step-by-step explanation:
To find the average, we can simply add up the percentages and divide by how many there are.
We can do this by:
= 71.25%
This is Pythagorean theorem.
We already know a and c.
a = 4 and c = 10
4² + b² = 10²
16 + b² = 100
Subtact 16 from each side.
b² = 84
Square root of each side:
b = ≈9.165 or √84
