Find the critical points of dy/dx=15-2y-y^2 and determine if they are stable, unstable or semi-stable.

3...stable critical value, -5 unstable critical vale

Step-by-step explanation:

A critical value of the given differential is a value such that the left hand side of the equation is equal to zero, i.e, y such that

By the last equation the critical values of the given differential equation are y=-5, 3.

Now, since

It holdst that

and

hence 3 is a stable critical value.

Also note that

and

hence -5 is an unstable critical value.

15% chance.

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
