What is the intrist rate ? kind of need that to answer
Answer:
21w+3
Step-by-step explanation:
5w+9w+5+7w-2
14w+5+7w-2
21w+3
F the diameter is 1/2 mile, that is 0.5 mile, then the radius is 0.25 -half of it!
the angular speed is theta/time, which means
w=theta/time
but another formula for it is Velocity*radians
w=velocity*radians
velocity is 180 mph and radians are (revolution/2 radius), that is:
w=180*(1/2*0.25)
and if we calculate this, we have: w=114.59, which is the correct answer!
Answer:
The correct answer for the second one is,
or
<-- there's no plus/minus sign.
<-- root.
<-- root.
<-- don't forget to distribute the negative.
