Find the value of c that (x-4) is a factor of the polynomial f(x)=cx^3-4x^2+2x+3

What is the point of inflection for the function f(x)=2cos4x on the interval (0, pi/2)

The point (-7, -24) is on the terminal ray of angle 0 which is in standard position. a student found the six trigonometric values for angle e. the student's answers are shown. which value(s) are incorrect? sin(8) cos(8) 24 tan(0) sin(0)=25 cos(0) -- tan(ⓡ) - - 24 csc(o)=2 sec(0) --25 cot(6) - za csc(o) sec(0) cot(0) done

How do i answer this i do not get this at
