Write a polynomial function of least degree with integral coefficients that have the given zeros. 4,-1,6 f(x)=x^3-9x^2+14x+24

AlladinOne [14]

Answer:

see explanation

Step-by-step explanation:

Given the zeros of a polynomial, say x = a, x = b, x = c

Then (x - a), (x - b), (x - c) are it's factors

and the polynomial is the product of the factors

here x = 4, x = - 1, x = 6, hence

(x - 4), (x + 1) and (x - 6) are the factors

f(x) = a(x - 4)(x + 1)(x - 6) ← a is a multiplier

let a = 1, then expanding the first pair of factors

f(x) = (x² - 3x - 4)(x - 6) ← expand out the factors

= x³ - 3x² - 4x - 6x² + 18x + 24 ← collect like terms

= x³ - 9x² + 14x + 24

A wave has a frequency of 6.1 x 1014 Hz and a speed of 3.00 x 108 m/s. Use

slamgirl [31]

Answer:

(A) $4.9\times 10^{-7}\ m$

Step-by-step explanation:

Given:

Frequency of the wave (f) = $6.1\times 10^{14}\ Hz$

Speed of the wave (v) = $3.00\times 10^8\ m/s$

The wavelength equation of the wave is given as:

$\lambda=\dfrac{v}{f}$

Here, $\lambda \to wave\ wavelength$

Now, plug in the given values and simplify.

$\lambda=\frac{3\times 10^8}{6.1\times 10^{14}}\\\\\lambda=4.9\times 10^{-7}\ m$

Therefore, the wavelength of the wave is option (A) $4.9\times 10^{-7}\ m$
