The frequency (f) and length (l) of a wave are related by the following formula: f x l = 3.0 x 1010. consider that the wavelength of violet light is 1.3 x 10−8. what is the frequency of violet light?

2.3 × 10^18

Step-by-step explanation:

Your formula tells you ...

... F × (1.3 × 10^-8) = 3.0 × 10^10

Dividing by the coefficient of F, you have ...

... F = 3.0/1.3 × 10^(10-(-8))

... F ≈ 2.3 × 10^18

idk

step-by-step explanation:

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )
