Get started for freeThe writer wants to add a conclusion that reinforces the idea that Anderson focused on her singing as a way to fight intolerance. Which choice best accomplishes this goal? A) She rarely spoke of her Lincoln Memorial performance and didn't express anger toward the injustice she had experienced that day and throughout her life, preferring to influence people through the power of her singing.

C) She paved the way for and inspired other African American artists such as singers Leontyne Price and Jessye Norman, the latter of whom performed at an anniversary concert in Anderson's honor in 2014. D) She was a contralto, which is a type of classical singing voice that uses the lowest female vocal range, and while she was a talented singer even as a child, she did not have formal lessons until age fifteen.
What complex number is equivalent to the expression above if \(i=\sqrt{-1}\) ? A) 2 B) \(2-5 i\) C) \(-2+5 i\) D) \(-10-9 i\) $$ \frac{4}{n-3}=\frac{5}{n+2} $$
In Passage 2, the phrase "general consensus" (line 49) mainly serves to A) provide historical context for the current debate over learning in newborns. B) establish researchers' certainty about the onset of neurogenesis. C) indicate the broad agreement about the decline of neurogenesis that previously existed.

An investor is deciding between two options for a short-term investment. One option has a return \(R\), in dollars, \(t\) months after investment, and is modelled by the equation \(R=100\left(3^t\right)\). The other option has a return \(R\), in dollars, \(t\) months after investment, and is modeled by the equation \(R=350 t\). After 4 months, how much less is the return given by the linear model than the return given by the exponential model? A) \(\$ 1,400\) B) \(\$ 4,050\) C) \(\$ 6,700\) D) \(\$ 8,100\) $$ n-\sqrt{2 n+22}=1 $$
