Answer:

D. It closely fits the data points.

Step-by-step explanation:

This is a negative linear relationship.

It's not possible to draw a straight line through all the points but D is pretty close to the points on the plot.

Will Mark Brainlest help me please

saveliy_v [14]

p(x) × q(x)

= (3x² - x + 1) × (2x² + 3x - 2)

= 6x⁴ + 9x³ - 6x² - 2x³ - 3x² + 2x + 2x² + 3x - 2

= 6x⁴ + 7x³ - 7x² + 5x - 2

Answer:

AC = 6√3 in

Step-by-step explanation:

<h3>Finding the length of the chord:</h3>

Join OC. Now ΔAOC is an isosceles triangle as OA = OC =radius.

∠A = ∠C = 30.

∠A + ∠C + ∠AOC = 180 {angle sum property of traingle}

30 + 30 + ∠AOC = 180°

∠AOC = 180 -60

∠AOC = Ф = 120°

Find the length of radius using the bellow formula.

$\sf \boxed{\bf Arc \ length = \dfrac{\theta}{180}\pi r}$

Ф = 120°

Arc length = 4π

$\sf 4\pi =\dfrac{120}{180}*\pi *r\\\\ r =\dfrac{4\pi * 180}{120*\pi }\\\\ r = 6 \ in$

$\sf \boxed{\bf chord \ length = 2rSin \ \dfrac{\theta}{2}}$

$\sf b = 2*6*Sin \ \dfrac{120}{2}\\\\ b = 2 *6 * Sin \ 60^\circ\\\\ b = 2 * 6 * \dfrac{\sqrt{3}}{2}\\\\ \b = 6\sqrt{3}$

$\sf \boxed{\bf AC = 6\sqrt{3} \ in}$

Someone help please I'm having a hard time understanding

Over [174]

Answer:

the angle shown is a straight angle value of which is equal to 180°

3x + 30. 6 = 180

3x = 180 - 30. 6

3x = 149.4
