thank you so much! it's really clear now with the way you've explained it

this is what i got from the 2nd problem of the total 7 digits in the number he knows the first 5 that leaves 2 for him to find out with 0 not being the last number so he knows 10 possible for the 6th and 9 possible for the 7th (not 0) 10 * 9 = 90 possible...

#3 I got this answer (20000*.7)-(3000*.3) =14000-900 =$13,100. expected profit Is this right

Ok so I really need help with problem 1 I have no clue

16 years ago

So the answer for #1 is 1/35 is that I have to do for that problem though?

can someone please help me with this question I'm in really need with this question

16 years ago

this still isn't the correct answer though. my book says that it's 0.204

yeah the coefficient of static friction is 0.5 and coeffient of kinetic friction is 0.4. theta is measured below the horizontal

16 years ago

yes i measured s0 from point A so it's 0

I see how this would be correct but the book says the answer is 11.81ft/s and the vertical rise is 2.16 ft

thank you so much! this really helped me see where i went wrong

16 years ago

would beta be different for part b?

16 years ago

wait it would be different. wouldn't you just subtract 15 since it's starting from an angle with 15 less degrees?

16 years ago

thanks! i was multiplying by 0.82 instead of dividing

sorry the angle theta is measured below the radius to the vertical

i see where you went wrong. you have 7.5E6 and the second radius and it's supposed to be 7.0E6. yeah that's how i worked the problem. i converted my answer wrong when i went from m/s to km/h thank you for your help!

I'm in this class too :/ For this problem, you have to use both equations F=Ma and F=(mv^2)/r Step 1: solve for F using F=Ma 5.70kg x 9.81 m/s^2 = 55.917 N Step 2: plug this into the other equation 55.917N = (2.40kg x v^2)/0.500m (55.917N x .5m)/2.40kg =1...

So y2-y1=m(x2-x1) y-(-2)=-6(x-(-1) y=6x-1 therefore the slope of tangent is 6?

weight normal is about 81 and weight parallel is about -519

Yes, but it has to be about evolution in general, not just humans.

Whaaaat?! A person in Texas buys snowblower. Is it really make sense for you?

Yea, I just had that question on a test... I chose D, and it was correct.
