The relationship between altitude and the boiling point of a liquid is linear. At an altitude of 8100 ft, the liquid boils at 20

Zinaida [17]

9514 1404 393

Answer:

b = -0.0012a +211

208.36 °F at 2200 ft

Step-by-step explanation:

We are given two points:

(a, b) = (8100, 201.28) and (4300, 205.84)

The slope of the desired line can be found using the slope formula:

m = (y2 -y1)/(x2 -x1)

m = (205.84 -201.28)/(4300 -8100) = 4.56/-3800 = -0.0012

The "y-intercept" of the function can be found from ...

y-intercept = b -ma

y-intercept = 201.28 -(-0.0012)(8100) = 211.00

So, the function of interest is ...

b = -0.0012a +211

__

At 2200 ft, the boiling point is ...

b = -0.0012×2200 +211 = -2.64 +211 = 208.36

The boiling point of the liquid at 2200 ft is 208.36 °F.

Apply division algorithm to find the quotient and remainder on dividing the polynomial 3 x^ + 4 x^ square + 6 x + 9 by x^ + 3x +

Ulleksa [173]

I suppose you mean

$\dfrac{3x^3+4x^2+6x+9}{x^2+3x+7}$

$3x^3=3x\cdot x^2$ , and if we multiply $x^2+3x+7$ by $3x$ we get $3x^3+9x^2+21x$ . Subtracting this from the numerator gives a remainder of $-5x^2-15x+9$ .

$-5x^2=-5\cdot x^2$ , and multiplying $x^2+3x+7$ by $-5$ gives $-5x^2-15x-35$ . Subtracting this from the previous remainder gives a new remainder of $44$ .

$44$ has no remaining factors of $x^2$ in it, so we're done, and

$\dfrac{3x^3+4x^2+6x+9}{x^2+3x+7}=\underbrace{3x-5}_{\rm quotient}+\dfrac{\overbrace{44}^{\rm remainder}}{x^2+3x+7}$
