The angular velocity is 16 radians per second

<u>Solution:</u>

The angular velocity of point is given by formula:

w = \frac{v}{r}

Where,

w is the angular velocity in radians

v is the linear velocity

r is the radius

Given that diameter of wheel is 10 feet

radius=\frac{diameter}{2}

radius = \frac{10}{2}=5

Thus radius is 5 feet

A point on the rim of a wheel moves with a velocity of 80 feet per second

Linear velocity = v = 80 feet per second

Therefore, angular velocity is given as:

w = \frac{80}{5} = 16

Thus angular velocity is 16 radians per second

86 teams enter the race .if the race begins with 16 dogs on each team how many dogs will enter the race
brilliants [131]

Answer:

1376 dogs

Step-by-step explanation:

This is just a multiplication problem if we convert the words to mathematical formulas.

There are 86 teams: a_1,a_2,...a_8_5,a_8_6. Each team has 16 dogs: a_1=16,a_2=16,...a_8_5=16,a_8_6=16.

So, we can add up 16 to itself 86 times, which is just 16 * 86 = 1376

Thus, the answer is 1376 dogs.

Hope this helps!

Step-by-step explanation:

=2x2+−4x+8+3x2+15x+−12

Combine Like Terms:

=2x2+−4x+8+3x2+15x+−12

=(2x2+3x2)+(−4x+15x)+(8+−12)

=5x2+11x+−4
