Re-write the quadratic function below in Standard Form y= –2(x + 5)(x – 4)

Naddik [55]

Answer:

y = - 2x² - 2x + 40

Step-by-step explanation:

Standard form of a quadratic is y = ax² + bx + c : a ≠ 0

Given

y = - 2(x + 5)(x - 4) ← expand factors using FOIL

= - 2(x² - 4x + 5x - 20)

= - 2(x² + x - 20) ← distribute parenthesis by - 2

= - 2x² - 2x + 40 ← in standard form

Need assistance with the question attached

natulia [17]

Answer:

x = $\frac{4\pi }{9},\frac{10\pi }{9}$

Step-by-step explanation:

Given equation is,

$\sqrt{3}\text{tan}(\frac{2x}{3})+1=0$

By solving this equation,

$\text{tan}(\frac{2x}{3})=-\frac{1}{\sqrt{3}}$

$x=\frac{2}{3}\times \text{tan}^{-1}(-\frac{1}{\sqrt{3}})$ [tangent of any angle is negative in IInd and IVth quadrants]

x = $\frac{2}{3}\times (\frac{2\pi }{3})$ , $\frac{2}{3}\times (\frac{5\pi}{3})$

x = $\frac{4\pi }{9},\frac{10\pi }{9}$

Therefore, value of x in the interval of [0, 2π] are $\frac{4\pi }{9},\frac{10\pi }{9}$ .
