900,000,000. move the decimal until you have a number between 1-10 so move it 8 times and you'll have 9×10^8
The correct answer is 14.2 lb which is choice D.
Let:
F = minimum force required to prevent ball from rolling down the ramp
The formula will be:
F = w * sin theta
F = w * sin (39 degrees)
F = 22.6 * sin (39)
= 14.2 lb (this is rounded to the nearest tenth)
10 is the initial value, found when x=0. I don't know what you are measuring by "0" and "10" here, so can't be more specific.
