Ascientist cools some water at a constant rate. the graph and table show how the temperature of the water changes with time. which function models this situation? a: a(n)=46-4^n-1b: a(n)=46-4^n+1c: a(n)=46-(n-1)x4

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
