Answer:
The annual interest rate was $1487.50
Step-by-step explanation:
All you do is 2975 divided by2=1487.50
By the Intersecting Secants Theorem we have
2x(2x+7)=x(x+23)
4x^2+14x=x^2+23x
3x^2=9x
3x=9
x=3
Since DY is length 2x,
the length of DY is 6.
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
