a) one rational solution

b)two irrational solutions

c)sum of two roots equal to zero

d)products of da roots as -1

the no of irrational roots of da eq

x⁴ - 2 x² -x + 2 -   =0

a)0      b)2       c)3     d)4

sry fr posting da q wrong  but da above one is actual q plzzz help unble to solve it

ohhk ill de q is ::  on 2 diff tracks,the winners of the 1 km ran thier races in 2min,27.15sec and 2 min and 28.15 sec respectively....in order to conclude dat teh runner wth shorter time was indeed faster ,how much longer can da other track be in actual length ??

the zero gravity research facility at the NASA leis research center includes a 145 m drop tower.this is an evacuated vertical tower through which among other possibilities ,a 1m daimeter  sphere containing an experimental package can b dropped

(a)how long is the sphere in free fall?

(b)wat is its speed just as it reaches a cathing device at the bottom of the tower?

(c)when caught the sphere experiences an avg deceleration of 25 gm as it speed is reduced to zero .through wat dist it travel during the deceleration?

a swimmer wishes to cross a 500 m wide river flowing at 5km/hr his speed with respect to water is  3 km/hr .

cthe man has to reach the other shore at da point directly opp to his starting point .if he reaches the other shore sumwere else hw has to walk down to this point find the minimum distance he has to walk ?//
