Which of the following are solutions to the equation sinxcosx = - 1/4
Dafna1 [17]

The equation is given below as

\sin x\cos x=-\frac{1}{4}

Recall that

\begin{gathered} \sin 2x=2\sin xcosx \\ \text{which means that } \\ \frac{\sin2x}{2}=\sin x\cos x \end{gathered}

Therefore, equating the two-equation, we will have

\frac{\sin 2x}{2}=-\frac{1}{4}

cross multiply, we will have

\begin{gathered} \sin 2x=-\frac{1}{4}\times2 \\ \sin 2x=-\frac{1}{2} \end{gathered}

Therefore,

we will get the arc sign of both sides in radians to get

\begin{gathered} 2x=\sin ^{-1}(-\frac{1}{2}) \\ x=\frac{1}{2}\sin ^{-1}(-\frac{1}{2}) \end{gathered}

In radians, the final answer will be

\begin{gathered} x=\frac{7\pi}{12}+n\pi \\ \text{and} \\ x=\frac{11\pi}{12}+n\pi \end{gathered}

Therefore,

The finals answers are OPTION A and OPTION D

Cameron Indoor Stadium at Duke University is one of the most revered sites in all of college basketball, as well as in all of sp
vampirchik [111]

Answer:

Step-by-step explanation:

The domain of a function is the set of values that satisfies the independent variable while the range of the function is the set of values that satisfies the dependent variable.

Since for each game, the amount of money that the Duke Blue Devils’ athletic program brings in as revenue is a function of the number of people in attendance, then the dependent variable is the amount of money while the independent variable is the number of people. The domain is between 0 and 9460 people. Therefore, the domain of this function is

0 ≤ x ≤ 9460

Where x represents number of people.

For the range, the lowest total sales is 0 × 45.5 = $0

The highest total sales is

9460 × 45.5 = $430430

The range is

0 ≤ y ≤ 430430

Where y represents total sales
