The answer is Radical 6.

This is because if you use Cosine and the angle measured 30. You would put adjacent over hypotenuse, which is
Cos (30) = X/radical 8

Put this into your calculator to get Radical 6

Determine the roots of f(x) = -12-2.1x+18x^2-2.75x^3 graphically. in addition, determine the first root of the function with
vesna_86 [32]

The given function is that is a cubic polynomial

f(x)=-12-2.1x+18x^2-2.75x^3

when arranged in descending order that is from highest degree to lowest degree

f(x)=-2.75x^3+18x^2-2.1x-12

Since it is a three degree polynomial it has three roots.

According to rational root theorem , the possible roots of the above expression that is factors of  \frac{12}{2.75}=\frac{48}{11}  are \pm1, \pm 2, \pm 3, \pm 4, \pm 6, \pm 8, \pm 12, \pm 24, \pm 48, \pm\frac{1}{11}, \pm\frac{2}{11}, \pm\frac{3}{11}\pm\frac{4}{11}\pm\frac{6}{11},\pm\frac{8}{11},\pm\frac{12}{11}, \pm\frac{24}{11},\pm\frac{48}{11}

As you can see from the graph all roots of this polynomial are real.

The smallest positive root is 0.954 and smallest negative root are -0.724.
