muminat

Answer:

$\boxed{\sf \ \ \ 3x^2-7x+2 \ \ \ }$

Step-by-step explanation:

Hello,

There are a lot of polynomials which have 2 and 1/3 as zeroes,

I can show you one below

$3(x-2)(x-\dfrac{1}{3})=(x-2)(3x-1)=3x^2-x-6x+2=3x^2-7x+2$

hope this helps

Solve a = b - 4/ c for b.

ahrayia [7]

Answer:

ac + 4 = b

Step-by-step explanation:

Step 1: Write equation

a = (b - 4)/c

Step 2: Multiply both sides by <em>c</em>

ac = b - 4

Step 3: Add 4 on both sides

ac + 4 = b

The top of two poles of height's 20m and 14m are connected by the wire

Hatshy [7]

Answer:

The correct option is;

10 m

Step-by-step explanation:

The parameters given are;

Height of the first pole = 20 m

Height of the second pole = 14 m

The angle the wire connected to their top makes with the horizontal = 30°

The vertical height subtended by the inclined wire, h = The difference in height between the two poles = 20 - 14 = 6 m.

Let the horizontal distance between the two poles = D

Therefore;

The horizontal length of the wire = D

From trigonometric ratios, we have;

$tan(30 ^{\circ}) = \dfrac{h}{D} = \dfrac{6}{D}$

Which gives;

$D = \dfrac{6}{tan(30 ^{\circ}) } = 10.39 \ m\approx 10 \ m$

The correct option is 10 m.
