Homework Statement A 100-N uniform ladder, 8.0m long, rests against a smooth vertical. The coefficient of static friction between ladder and floor is 0.40. What minimum angle can the ladder make with the floor before it slips? The Attempt at a Solution Not really sure where to start...

i figured it out. it was two steps

Homework Statement A sker reaches a speed of 56 m/s on a 30 degree ski slope. Ignoring friction, what was the minimum distance along the slope the skier would have had to travel, starting from rest? Homework Equations Which equation do i start with? I'm pretty sure i have to find the...

Is the velocity is constant, then there is no acceleration. Correct?

Homework Statement A cheetah can maintain its maximum speed of 100 km/hr for 30.0 seconds. What minimum distance must a gazelle running 80.0 km/hr be ahead of the cheetah to escape? Homework Equations What equation do i start his out with? I'm not even sure what to start lookinf or...

i think i got it! if I'm correct i can factor out a (3x+2)^3 and that makes thing a whole lot simpler

well i'll sure try to do it. thank you very much for your time and this lengthy explanation!

Homework Statement I have a quiz tomorrow and i know a problem like this is going to be on it and i need to figure out the process Homework Equations the expression is: (2x^2-3x+1)(4)(3x+2)^3(3)+(3x+2)^4(4x-3) The Attempt at a Solution i know the final answer(3x+2)^3(36x^2-37x+6)...

Homework Statement Find all solutions of the equation. Homework Equations 4x^4+25x^2+36=0 The Attempt at a Solution Where do i start here? do i use the quadratic formula? I'm thinking i can factor out a x^2 to make it{ x^2(4x^2+25x+36) }and from there i can do the quadratic...

thanks everybody

I know this is a dumb question but dumb questions are easier to fix than dumb mistakes so here goes. Is 2x(x)= 3x or 2x(x) = 2x^2

Homework Statement I have to rewrite the following expression using a radical. I know the correct answer according to my textbook is 4x√x. Homework Equations 4x ^{3/2} The Attempt at a Solution √4x^3 is this the right start?

But to simplify it further to i divide the exponents of the variables by the index of the radical? I'm sorry if my terminology is bad and if my equations aren't right I'm new to this forum so I'm trying to get it right.

Homework Statement When there are exponents in a radicand as shown below, do i just divide them out? Homework Equations ∛(x^6 y^4 ) The Attempt at a Solution x^2 y^4 ?

Yes sorry i meant to say -47/3. I wasnt sure how you arrived at -48/3 but i realize i forgot about finding the common denominator
