170 cm. The unknown length on the left is 21 cm
Answer:
20
Step-by-step explanation:
pilot flew a 400-mile flight in 2.5 hours flying into the wind . Flying the same rate and with the same wind speed, the return trip took only 2hours with a tailwind
The speed can be defined as the ratio distance over time, but in this case the pilot is flying at the speed of the plane as well of speed of the wind. We can denote speed of plane as "s" and speed of the wind as "k"
Then the speed of the plane=(s-k) this is because it is moving in the opposite direction of the wind.
But From the question, the plane distance=400mile and the corresponding time =2.5 h
Then the speed of the plane=(s-k) =400mile/2.5
=160mph
By the time it return from trip, the speed the plane flew with is (s+k) because the wind is at the rear.
From the question, the plane distance=400mile and the corresponding time =2 h
Then (s+k)= (400/2)
(s+k)=200mph
Answer:
Step-by-step explanation:
To find the angular velocity divide the revolutions by the time
so
Remember that
Convert rev/sec to rad/sec
assume 
We are given with the best fit line
<span>y = 2,500x - 2,500
The y-intercept is -2500
and the slope is 2500
This line can be translated into the following statements:
At the start of the operations, there is a negative profit of -2500. Each year, the profit increases by 2500</span><span />
