6 0

Answer:

Yes

Step-by-step explanation:

f(x) = x³ − 9x² + 11x + 21

f(3) = (3)³ − 9(3)² + 11(3) + 21

f(3) = 27 − 81 + 33 + 21

f(3) = 0

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}

Let A = Aaron's age today and M = Maria's age today.
kondor19780726 [428]

Aaron is 4 years and Maria is 14 years old.

A = Aaron's age today

M = Maria's age today.

a. The equation based on the statement given will be:

M = A + 10

b. Maria's age based on the statement in 6 years will be:

= (A + 10) + 6

= A + 16

c. Based on the information above, the equation to solve their ages will be:

A + 16 = 2(A + 6)

A + 16 = 2A + 12

Collect like terms

2A - A = 16 - 12

A = 4

Therefore, Aaron is 4 and Maria is 14 years.
