Step-by-step explanation:
(5x + 2)/x² = 5/x + 2/x²
= 5x^-1 + 2x^-2
Which is not a polynomial
I’m pretty sure it’s linear!
Answer:
Step-by-step explanation:
Given 3x-4y=65
Y=4
So 3x-4×4=65
3x-16=65
3x=65+16
X=81/3
X=27
So value of X is 27
Against the wind 100 m 15 sec = 6.67 mtrs / sec
With the wind 100 m 10 sec = 10 mtrs / sec
psa means plane velocity in still air
ws means wind speed
psa -ws = 6.67
psa + ws = 10
Adding both equations we get:
2 * psa = 16.67
psa = 8.34 meters per second
Since psa + ws = 10 and psa = 8.34 then wind speed = 1.66 meters per second
