7 0

Answer:

Step-by-step explanation:

f(x)=-x(x-4)

f(x)=-x²+4x

-x²+4x=0

x(-x+4)=0

x=0, x=4

(2)

4x²-x-3=0

(4x²+3x)-(4x-3)=0

x(4x+3)-1(4x+3)=0

x=1, x=-3/4

neonofarm [45]

Answer:

$\omega = 8\,\frac{rad}{s}$

Step-by-step explanation:

The translation speed of the wheel is:

$v=\frac{20\,m}{5\,s}$

$v=4\,\frac{m}{s}$

The angular speed of the wheel is:

$\omega = \frac{4\,\frac{m}{s} }{0.5\,m}$

$\omega = 8\,\frac{rad}{s}$
