If f(x) = kx^3+ x^2 − kx + 2, find a number k such that the graph of f contains the point (k, -10)
Elina [12.6K]

If we write k where we see x in the equation and set the result equal to -10, we get the result.

  • f(k)=k(k)^3+k^2-k(k)+2
  • =k^4+k^2-k^2+2
  • =k^4+2=-10
  • k^4=-12
  • k_{1}=\sqrt[4]{3}(-1-i)
  • k_{2}=\sqrt[4]{3}(-1+i)
  • k_{3}=\sqrt[4]{3}(1-i)
  • k_{4}=\sqrt[4]{3}(1+i)

This is my very first trig problem and I'd like to know how to tackle this. Please explain how I can do problems like these in t
Paha777 [63]

\tan(50°)  =  \frac{QR}{PQ} \Leftrightarrow QR = PQ \tan(50°) = 8.1 \tan(50°) \approx9.65 \\  \cos(50°)  =  \frac{PQ}{PR} \Leftrightarrow PR =  \frac{PQ}{\cos(50°)}  = \frac{8.1}{\cos(50°)} \approx12.6
