Explain how knowing that 5÷8 = 0 .625 helps you write the decimal for 4 5/8
Korolek [52]
<span>So lets see how does knowing that 5 divided by 8 = 0.625 helps us write the decimal for 4 5/8. First lets write 5 divided by 8 like a fraction: 5/8=0.625. Now we can see that 5/8 is in the number 4 5/8 so we can easily write it as: 4 + 0.625 = 4.625. So this is how it helps us. </span>

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)
