To answer this item, we use dimensional analysis and conversion factor, 1 revolution is equal to 2π rad. Using the concept and the given,
            
                        n = (14.2 revolutions / 8 seconds)(2π rad/1 rev)
                          n = 11.15 rad/s
Thus, the angular velocity is equal to 11.15 rad/s.

Which equation models a line that passes through point (-2,2) And has a slope of -8
trasher [3.6K]

So we will be using y=mx+b form, in which m = slope and b = y-intercept. Since we know the slope (-8), all we need to do is solve for the y-intercept. We can do this by inserting (-2,2) into the equation and solve for b.


2=-8(-2)+b


Firstly, do the multiplication: 2=16+b


Next, subtract 16 on both sides, and your answer will be -14 = b



Using the previous info we have, our equation is y = -8x - 14

Dracula jumped 5 times every 30 minutes at that rate, how long,in minutes will it take to jump 6 times?
pentagon [3]

Answer:

36 minutes

Step-by-step explanation:

If I read this correctly, Dracula jumps 1 time every 6 minutes. If he jumped 5 times in 30 minutes, then that means when he jumped a sixth time, it was 36 minutes that passed since:

30 / 5 = 6

So, if he were to jump a sixth time:

30 + 6 = 36

Therefore, Dracula jumps 1 time per 6 minutes.
