Answer:

The slope of -3.824 means that if we increase engine size by 1 unit, the mpg will decrease by 3.824 units

Explanation:

mpg=36.91−3.824•Engine size

Writing as y=mx+c then

mpg=−3.824•Engine size+36.91

Where mpy represent y, -3.824 represent m, engine size represent x and 36.91 represent c

Since from the equation y=mx+c m is the slope and c is the y-intercept, therefore,

The slope of -3.824 means that if we increase engine size by 1 unit, the mpg will decrease by 3.824 units

A particular motor rotates at 3000 revolutions per minute (rpm). What is its speed in rad/sec, and how many seconds does it take
raketka [301]

Answer:

ω=314.15 rad/s.

0.02 s.

Explanation:

Given that

Motor speed ,N= 3000 revolutions per minute

N= 3000 RPM

The speed of the motor in rad/s given as

Now by putting the values in the above equation

ω=314.15 rad/s

Therefore the speed in rad/s will be 314.15 rad/s.

The speed in rev/sec given as

ω= 50 rev/s

It take 1 sec to cover 50 revolutions

That is why to cover 1 revolution it take

\dfrac{1}{50}=0.02\ s
