Step-by-step explanation:
graphed it.
Factor 28 and 49
28
1*14
1*2*7
49
7*7
7 is the answer
4 2/3 /2 /5
14/3 / 2/5 cross multiply
7/3 / 1/5 multiply 7 and 5 and 3 and 1
35/3 simplify
11 2/3
Answer:
Step-by-step explanation:
f(-2)= 4(-2)^2 + 3 = 4(4) + 3 = 16 + 3 = 19
g(19) = 3(19) + 2 = 57 + 2 = 59
g(-2)= 3(-2) + 2 = -6 + 2 = -4
f(-4)= 4(-4)^2 + 3 = 64 + 3 = 67
Your answer would be the time in takes for carbon-14 to elapse 3 half-lives.
