Answer:

\frac{1}{3}

Step-by-step explanation:

In this question, you would solve the for f(x) by plugging in the given value to x.

Solve:

\frac{1}{9}^\frac{1}{2}

Distribute the exponent to the numerator and denominator.

\frac{1^\frac{1}{2}}{9^\frac{1}{2}}

Simplify.

\\\\\frac{1^\frac{1}{2}}{9^\frac{1}{2}}\\\\9^\frac{1}{2}=3\\\\\frac{1^\frac{1}{2}}{3}}\\\\

Use the 1^a = 1\,\text{} rule for the numerator:

\frac{1}{3}

Your final answer would be \frac{1}{3}

At noon, a barista notices she has $20 in her tip jar. If she makes an average of $0.50 from each customer, how much will she ha
RSB [31]

Answer:

She has $20 + $0.50n in her tip jar.

Step-by-step explanation:

Amount in tip jar at noon = $20

Average amount made from each customer = $0.50

Number of additional customers served after noon = n

Therefore, we have:

Additional amount made after noon = Average amount made from each customer * Number of additional customers served after noon = $0.50 * n = $0.50n

Amount in tip jar = Amount in tip jar at noon + Additional amount made after noon = $20 + $0.50n

Therefore, she has $20 + $0.50n in her tip jar.
