Answer:

a is proportional to b

a=kb

k is proportionality constant

k =a/b =3/12 =1/4

k=1/4 = a/b=a/18

1/4=a/18

a=18/4 =9/2 =4.5 answer

D(x)=(x^2-12x+20)/(3x)
krok68 [10]

Answers:

Vertical asymptote: x = 0

Horizontal asymptote: None

Slant asymptote: (1/3)x - 4

<u>Explanation:</u>

d(x) = \frac{x^{2}-12x+20}{3x}

      = \frac{(x-2)(x - 10)}{3x}

Discontinuities: (terms that cancel out from numerator and denominator):

Nothing cancels so there are NO discontinuities.

Vertical asymptote (denominator cannot equal zero):

3x ≠ 0  

<u>÷3</u>   <u>÷3 </u>

x ≠ 0

So asymptote is to be drawn at x = 0

Horizontal asymptote (evaluate degree of numerator and denominator):

degree of numerator (2) > degree of denominator (1)

so there is NO horizontal asymptote but slant (oblique) must be calculated.

Slant (Oblique) Asymptote (divide numerator by denominator):

  •        <u>(1/3)x - 4    </u>
  •    3x)    x² - 12x + 20
  •             <u>x²        </u>
  •                  -12x
  •                  <u>-12x         </u>
  •                             20 (stop! because there is no "x")

So, slant asymptote is to be drawn at (1/3)x - 4

Find the surface area
iragen [17]

Answer:

The surface area is 302 in²

Step-by-step explanation:

Known :

Long (l) = 11 in

Weight (w) = 6 in

Height (h) = 5 in

Asked :

Surface Area (Sa) = ...?

Answer :

Formula :

= 2(l.w) + 2(l.h) + 2(w.h)

= \boxed{2 (l.w + l.h + w.h)}

= 2 (11×6 + 11×5 + 6×5)

= 2 (66 + 55 + 30)

= 2 × 151

= <u>3</u><u>0</u><u>2</u><u> </u><u>in²</u>

So, the surface area is 302 in²
