For the following exercises, write the interval in set-builder notation

10. (-infinity, 6)
11. (4, infinity)
12. [-3,5)
13. [-4,1]u[9, infinity)
14. (-infinity, infinity)

10. (-infinity, 6)    Set Builder Form = { x : x < 6}

11. (4, infinity)  Set Builder Form = { x : x > 4}

12. [-3,5)   Set Builder Form = { x : -3 ≤ x < 5}

13. [-4,1]U[9, infinity)    Set Builder Form = {x :  x ∈ [-4,∞)  - (1,9)}

14. (-infinity, infinity)    Set Builder Form = {x :  x ∈ (-∞,∞)}

Step-by-step explanation:

Set Builder form of a set states the general definition of the given function without specifying each and every element of set.  

Now, here the given sets are:

10. (-infinity, 6)  

Set Builder Form = { x : x < 6}

11. (4, infinity)

Set Builder Form = { x : x > 4}

12. [-3,5)

Set Builder Form = { x : -3 ≤ x < 5}

13. [-4,1]U[9, infinity)

Set Builder Form = {x :  x ∈ [-4,∞)  - (1,9)}

14. (-infinity, infinity)

Set Builder Form = {x :  x ∈ (-∞,∞)}

the factors of 24 are 1, 2, 3, 4, 6, 8, 12 and 24. hope this ! mark brainliest! you v much! : )

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
