i did not understand it. please solve it till the end

Can you please gimme the whole procedure ?

Thaanks that helped a lot <3

But did u use pythagoram theorom an how did u manipulate it ? And thanks because the answer is right .

Shouldnt you have used the formula of volume of cone which is 1/3 pi r^2 h . And the answer should be 8 or 50 but by your procedure i m not getting it .I appreciate you help.

Okaay thaat makes sense but do i get 8 or 50 as your answer if u solve it fully .thanks .

Yea i did made a diagraam and thanks .

I know that but i wanna factor it till the end and how can i do it when its missing the squared term.

Thank you and yea i tried it but i was makin a minor mistake and now i see it .

yea i was wondering that too but there isn't any height given so i think i will leave the answer with the height !thanks <3

Reiny the answer is suppose to be 65/(120+4h) . I dunno i m not geting itt

I mean 75 not 65

According to reputation theory "ontogeny repeats phylogeny " it means that an individual during it development repeats it's ancestors history

50N s=5t+2t²m v=5+4tm/s a=5m/s² Given: m=10kg So,F=ma F=10*5 F=50N

s=5t+2t²m v=5+4tm/s a=4m/s² Given: m=10kg So,F=ma F=10*4 F=40N

Light as balloons

I want to know answer
