Answer:

x = ± 2, x = 3

Step-by-step explanation:

note that x = 2 gives

2³ - 3(2)² - 4(2) + 12 = 8 - 12 - 8 + 12 = 0

Hence x = 2 is a root and (x - 2) is a factor

x³ - 3x² - 4x + 12 ÷ (x - 2)

= (x - 2)(x² - x - 6)

= (x - 2)(x + 2)(x - 3), hence

(x - 2)(x + 2)(x - 3) = 0

equate each factor to zero and solve for x

x - 2 = 0 ⇒ x = 2

x + 2 = 0 ⇒ x = - 2

x - 3 = 0 ⇒ x = 3

The cylinders are similar. The volume of the larger cylinder is 9648 cubic inches. What is the volume of the smaller cylinder?

zalisa [80]

Hey there :)

The volume formula of a cylinder is:
V = $\pi$ r²h

The volume of the larger volume is given to be 9648³ and the height is 18 in
We need to find the radius first

9648 = $\pi$ r²(18)
$\frac{9648}{18}$ = $\pi$ r²
536 = $\pi$ r²
$\frac{536}{ \pi}$ = r²
$\sqrt{ \frac{536}{ \pi } }$ = r
r ≈ 13.06

The ratio of the big cylinder to small cylinder is:
18 : 9 (given height)
So the big cylinder is 2 times bigger than the small cylinder
Therefore the radius of the big cylinder is as well 2 times bigger

$\frac{13.06}{2} = r$
r ≈ 6.53 ( the radius of the small radius )

V (of small cylinder) = $\pi$ (6.53)²(9)
= 1206 in³
