2. 3 tan(x) = 2 sin(2x) from [0,2π)

3. sec(x) cos(3x) = 0 from [–π /2, π /2]

4. sec(x) cos(3x) = 0 from [–π/2, π/2]

5. "4cos^4(x) – 5cos^2(x) + 1 = 0 from [0,2π)

Can you guys plz answer this question in order and quickly plz i will give 30 points

Arandom high school question but a hard one

Will give brainliest plz hurry lexie surveyed 4 teenagers to find out approximately how many hours, per week, they read for fun, and how many siblings they have. brooke said she reads about 10 h a week for fun, and that she has 5 siblings. celia said she has 1 brother and 1 sister and reads for fun about 3 h each week. henry said he has 2 brothers and reads for fun about 30 min each week. jude said he doesn't read for fun and has 3 brothers and 3 sisters. use this information to complete the data table. express your answers as whole numbers or decimals. name hours of fun number of siblings brooke celia __ henry jude
