Suppose that \( \ln 3= \) a and \( \ln 11=b \). Use properties of logarithms to write the logarithm in terms of a and \( b \). \( \ln \sqrt[3]{33} \) \( \ln \sqrt[3]{33}=\square \)

7. Ed is training for a race. He ran 12.56 miles on one day and 12.98 miles the next day.

Solve: \( |2 x+1| \geq 5 \) Glve your answer as an interval or union of intervals. Only use integers or fractions, no decimal

Use the change-of-base formula and a calculator to evaluate the logarithm. \( \log _{7} 42 \) \( \log _{7} 42 \approx \square \) (Do not round until the final answer. Then round to the nearest thousandth as needed.)

Describe the end behavior of the polynomial function, \( F(x) \). (A) as \( x \rightarrow-\infty, f(x) \rightarrow-\infty \) and as \( x \rightarrow \infty, f(x) \rightarrow-\infty \) (B) as \( x \rightarrow-\infty, f(x) \rightarrow \infty \) and as \( x \rightarrow \infty, f(x) \rightarrow-\infty \) (C) as \( x \rightarrow-\infty, f(x) \rightarrow-\infty \) and as \( x \rightarrow \infty, f(x) \rightarrow \infty \) (D) as \( x \rightarrow-\infty, f(x) \rightarrow \infty \) and as \( x \rightarrow \infty, f(x) \rightarrow \infty \)
