Physics
On an extra note. I've done a lot of the practice problems and gotten those wrong... I don't know why I keep getting this wrong... But my answers for part a have been fairly close it seems like I keep getting my y-speed when the engine fails wrong by about 2.something ...

Physics
A rocket is launched at an angle of 56.0° above the horizontal with an initial speed of 103 m/s. It moves for 3.00 s along its initial line of motion with an acceleration of 31.0 m/s2. At this time its engines fail and the rocket proceeds to move as a free body. (a) Find t...

Economics
I am looking for an answer to this very same question with a different dollar amount "If the average adult produces \$70,000 of output per year, how much output is lost annually as a result of adult deaths from secondhand smoke?" according to the news/study provided b...

solve the equation in the real number system. 2x^4-23x^3+75x^2-88x+28=0 What are the real solutions of the equations? please show work. I do not know how to work this at all

algebra
use the rational zero theorem to list the potential rational zeros of the polynomial function. Do not attempt to find the zeros. f(x)=2x^7-x^5+8x^4+52

Find a bound on the real zeros of the polynomial f(x)=x^4+4x^3-8x-6 can someone help me, I am confused and don't know where to start.

A fair, six-sided die is rolled eight times, to form an eight-digit number. What is the probability that the resulting number is a multiple of 8? Express your answer as a common fraction. I think the last 3 digits have to be divisible by 8 to be a multiple of 8...

college algebra
i am not understanding why you put 0 for the first answer. it doesn't seem like you added or did any type of math to get the 0. can you explain more. this is all confusing to me.

college algebra
we would let f(x)=x^3-7x^2+25x-39 = 0. we would factor to get (x-3)(x^ 2-4x+13). find the solutions to the second part (x^2-4x+13)using the quadratic formula. (the first part is x=3)
