Flauer [41]

Answer:1,2,3

Step-by-step explanation:

F(x)= $x^{3}$ +2 $x^2$ - $5x$ - $6$ =0

disintegrating 2 $x^2$ to $x^2$ + $x^2$

$x^{3}$ + $x^2$ + $x^2$ - $5x-6$ =0

$x^2$ $\left ( x+1\right )$ + $x^2$ -5x-6=0

$x^2$ $\left ( x+1\right )$ + $x^2$ -6x+x-6=0

$x^2$ $\left ( x+1\right )$ + $\left (x-6 \right )$ $\left ( x+1\right )$ =0

$\left ( x+1\right )$ $\left ( x^2+x-6\right )$ =0

$\left ( x+1\right )$ $\left ( x^2+3x-2x-6\right )$ =0

$\left ( x+1\right )$ $\left ( x+3\right )$ $\left ( x-2\right )$ =0

Answer:

37.7 mi²/h

Step-by-step explanation:

The area formula is ...

A = πr²

Differentiating with respect to time gives ...

dA/dt = 2πr·dr/dt

Filling in the given values, we have ...

dA/dt = 2π(3 mi)(2 mi/h) = 12π mi²/h

The area is increasing at the rate of about 37.7 mi² per hour.
