Arock outcrop was found to have 89.00% of its parent u-238 isotope remaining. approximate the age of the outcrop. the half-life of u-238 is 4.5 billion years old.

•757 mil years
•37 mil years
•12 mil years
•1.2 nil years

the answer would be 484

step-by-step explanation:

just multiply 0.484 times 1,000 (formula)

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
