Answer:

A and D

Step-by-step explanation:

<h2>a)</h2>

\frac{.5 rev}{.1 } = 5 rev/sec

-- Convert to radians

\frac{5 rev}{1 sec} * 2\pi =10 \frac{radians}{sec}

<h2 /><h2>d) </h2>

10\frac{rad}{sec}*\frac{60 sec}{1 min}  = 600 rad/min

We know that

<span>The angular velocity is 10π rad/sec
step 1
convert to rad/min
1 min-----60 sec
X min----> 1 sec
X=1/60 min
V=</span>10π rad/(1/60)------> V=600 π rad/min

the answer is the option 
<span>D)The angular velocity is 600π rad/min.</span>

What are the zeros of f(x)=x(x-8)
Flura [38]

Answer:

The zeros are x=0,x=8

Step-by-step explanation:

f(x)=x(x-8)

To find the zeros, we set the equation equal to zero

0 = x(x-8)

Using the zero product property

x= 0  x-8=0

x=0  x=8

The zeros are 0,8
