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>

Help me solve this Algebra problem please​

Answer:

39858075

Step-by-step explanation:

Hello,

One basic way to see it is to compute the values.

   75 = 25 * 3

   225 = 75 * 3

   675 = 225 * 3

   etc ...

We can notice that this is multiplied by 3 every 10 years so we can compute as below.

year         population

1970 25

1980 75

1990 225

2000 675

2010 2025

2020 6075

2030 18225

2040 54675

2050 164025

2060 492075

2070 1476225

2080 4428675

2090 13286025

2100 39858075

So the correct answer is 39858075

Hope this helps.

Do not hesitate if you need further explanation.

Thank you
