<h3>Answer:</h3>

y = (x +2)(x -1)(x -3) . . . . or . . . . y = x³ -2x² -5x +6

<h3>Step-by-step explanation:</h3>

The graph shows y=0 at x=-2, x=1, and x=3. These are called the "zeros" or "roots" of the function, because the value of the function is zero there.

When "a" is a zero of a polynomial function, (x -a) is a factor. This means the factors of the graphed function are (x -(-2)), (x -1) and (x -3). The function can be written as the product of these factors:

... y = (x +2)(x -1)(x -3) . . . . . the equation represented by the graph

Or, the product can be multiplied out

... y = (x +2)(x² -4x +3)

... y = x³ -2x² -5x +6 . . . . . the equation represented by the graph

Suppose a is jointly proportional to b and c. if a=4 when b=8 and c = 9, then what is a when b=2 and c=18

asambeis [7]

From the given information, a exists jointly proportional to b and c.

then $$a \propto b c$

Therefore, the value of a exists 2.

<h3>What is the value of a?</h3>

Given, a exists jointly proportional to b and c.

$$a \propto b c$

Taking K as the constant of proportionality.

a = K b c

For b = 8 and c = 9, the value of a = 4

4 = K(8)(9)

4 = 72 K

Dividing the equation by 72, we get

$$K=\frac{1}{18}$

Using the value of K in the equation:

$$a=\frac{b c}{18}$

Substitute the values of b = 2 and c = 18, in the above equation

$$a=\frac{2 \times 18}{18} \\$

a = 2

Therefore, the value of a exists 2.

A wheel initially has an angular velocity of 18 rad/s, but it is slowing at a constant rate of 2 rad/s 2 . By the time it stops,

Kaylis [27]

Answer:13 revolution

Step-by-step explanation:

Given data

Wheel initial angular velocity $\left ( \omega \right )$ =18 rad/s

Contant angular deaaceleration $\left ( \alpha \right )$ =2 $rad/s^2$

Time required to stop wheel completely=t sec

$\omega =\omega_0 + \aplha t$

0 =18 + $\left ( -2\right )t$

t=9 sec

Therefore angle turn in 9 sec

$\theta$ = $\omega_{0} t$ + $\frac{1}{2}$ $\left ( \alpha\right )t^{2}$

$\theta$ = $18\times 9$ + $\frac{1}{2}$ $\left ( -2\right )\left ( 9\right )^2$

$\theta$ =81rad

therefore no of turns(n) = $\frac{81}{2\times \pi}$

n=12.889 $\approx$ 13 revolution
