Solve x^2-8x=3 by completing the square. Which is the solution set of the equation

kkurt [141]

Answer:

{-0.36, 8.36) to the nearest hundredth.

Step-by-step explanation:

x^2 - 8x = 3

(x - 4)^2 - 16 = 3

(x - 4)^2 = 19

Taking square roots:

x - 4 = +/- √19

x = 4 +/- √19

x = {-0.36, 8.36} to nearest 1/100.

Using this equation for Wien’s Law (λ = 2898/T), the wavelength most emitted by the Sun (T = 6000K) is approximately: a. 48.3 µm

Paladinen [302]

<h2>Option C is the correct answer.</h2>

Step-by-step explanation:

By Wien’s Law we have

$\lambda =\frac{2898}{T}$

where λ is in μm and T is in K

Given that

T = 6000 K

Substituting

$\lambda =\frac{2898}{6000}=0.483\mu m$

Option C is the correct answer.
