According to the Rational Root Theorem, what are all the potential rational roots of f(x) = 9x^4 – 2x^2 – 3x + 4?

julia-pushkina [17]

Answer: $\pm1,\frac{\pm1}{3},\frac{\pm1}{9},\pm2,\frac{\pm2}{3},\frac{\pm2}{9},\pm4,\frac{\pm4}{3},\frac{\pm4}{9}$

Step-by-step explanation:

The rational theorem states that if f(x) has integer coefficients and $\frac{p}{q}$ is a rational zero, then q is the factor of leading coefficient and p is the factor of constant term.

Given polynomial= $9x^4-2x^2-3x+4$

Now, Factors of leading coefficient q= $\pm9,\pm3,\pm1$

factors of constant term p= $\pm4,\pm2,\pm1$

according to rational root theorem the rational roots are in the form

$\frac{p}{q}=\pm1,\frac{\pm1}{3},\frac{\pm1}{9},\pm2,\frac{\pm2}{3},\frac{\pm2}{9},\pm4,\frac{\pm4}{3},\frac{\pm4}{9}$

If m/CHF = 106°, then what is m/FHD?

densk [106]

Answer:

74 degrees

Step-by-step explanation:

The two angles in question form a straight line (180 degrees)

180 = CHF + FHD

180 = 106 + FHD

180 - 106 = FHD

FHD = 74 degrees
