was my answer to #1 correct?

i am still lost even with the help of the other post. i don;t know where cm's come from and how to get them.

no forgot it at school but brought folder home, for #1 i get 133.3 N, #2 i don't know how to get N_1 and N_2, #3 i was told to do 950/350 but i believe he is just looking for a word answer, and #4 i get to the end but i don't know how to solve for vf^2.

the following four questions were from my test that i recentally took and i miss the day that we went over them and didn;t get the answers and haven;t had to time to check with my teacher about them, so i need some help on what the answers would be. thanks. 1. If the torque required to...

1. If the torque required to loosen a nut is 40.0 mN, what miminum force must be exerted by a mechanic to the end of a 30.0 cm wrench to remove the nut? 2. A uniform bridge 20.0 m long and weighting 4.00 x 10^5 N is supported by pillars located 3.00 m from each end. if a 1.96 x 10^4 N car is...

so what do you get for N_1 and N_2. I understand the other parts but am confused on how to get the answer for n_1 and n_2. I believe for #3 he is looking for a word answer and i know that 950/350 is not correct from asking kids in class about it.

I am curious how you got ur 900 to 1 ratio. Would the probably also be 1 % too.

The question is for the finite difference is: Show that the nth-order differences for the given function of deghree N are nonzero and constant. such as f(x) = 2x^3 - 5x^2 - x

I got 900 to 1. Is the correct or even close.

I have a word problem and then a finite difference problem. You are playing golf on the 4th hole of your favorite course. The green on this hole is circular with a radius of 20 yards. If the hole is located at the exact center of the green, what is the probablility that the ball will...

I was wondering if you an explantation for what you did since my teachers requires how we got it instead of just stating a thoure (how ever you spell it) about how we got it. it is kind of stuiped but makes perfect sense to him.

they both seem right to me just that the letters are changed and makes it a little organized and not messy. So the right answer is 4+1 = 5. Thanks for the help.

so would the values be 0 or 18. this question is confusing to me even when you did simplify it for me

If A=9^9999 + 9^-9999 and B= 9^9999 - 9^-9999. Then find the value of A^2 -B^2 + 1. would i just take the the numbers and square them to get the value. What should i do.
