Aparticle moving along a line has position s(t) = t^4 − 20t^2 m at time t seconds. determine: (a)- at which times does the particle pass through the origin? (b)- at which times is the particle instantaneously motionless.

Step-by-step explanation:

when s(t)=0

t^4-20t^2=0

t^2(t^2-20)=0

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.

what are you doing do you need examples of variable questions?

step-by-step explanation:

5a-1=9               bring the one over the =

5a=10                     divide by your variable

a=2
