Question

A grain silo consists of a cylindrical main section and a hemispherical roof. If the total volume of the silo (including the part inside the roof section) is 11,000 ft³ and the cylindrical part is 30 ft tall, what is the radius of the silo, correct to the nearest tenth of a foot?
r =  ft

The real solutions of the given equation are rational. List all possible rational roots using the Rational Zeros Theorem. (Enter your answers as a comma-separated list.)

x³ − 3x² − 4x + 12 = 0;  [−4, 4] by [−15, 15]

List all possible rational zeros given by the Rational Zeros Theorem (but don't check to see which actually are zeros). (Enter your answers as a comma-separated list.) I tried -1.5,\ 2.08,\ 5.42

P(x) = x³ − 6x² + 17

All the real zeros of the given polynomial are integers. Find the zeros. (Enter your answers as a comma-separated list. Enter all answers including repetitions.) I tried 3

P(x) = x³ − 9x² + 27x − 27
