If he starts out with $25 and to enter is $5 then he will be left with $20. 0.80 per ride then he can ride 25 times by diving 20 by 0.80
Answer:
The possible values of x are 90°, 30° and 150°.
Step-by-step explanation:
Given that,
sin(2x) = cos(x) where 0° ≤ x < 180°
We know that, sin(2x) = 2 sinx cosx
2 sinx cosx = cosx
Subtract cosx on both sides
2 sinx cosx - cosx = 0
cosx (2sinx-1)=0
It means, cosx = 0 and (2sin x -1 ) = 0
cos x = cos0 and sinx = 1/2
x = 90° and x = 30°, 150°
Hence, the possible values of x are 90°, 30° and 150°.

You do the amount deposited then you multiply that by the intrest rate ( but with the intrest rate you must move the decimal 2 times to the right) then you multiply how many years
