Answer:
Step-by-step explanation:
6/7 = 0.8571428571 = 0.86
Your answer is correct because the lines don’t intersect.
Answer:
decay rate is 2.44% per year
after 40 years, 400*(e^-0.976)=150.73 gm
300=400(e^-0.0244t)
0.75=e^-0.0244t
ln both sides
-0.2877=-0.0244t
t=11.79 years
t (1/2) occurs when ln(0.5)=-0.0244t
t=28.41 years
Have a nice day!
The answer to the selected problem is: that is a linear equation.
Answer:
D) -110
Step-by-step explanation:
x and y are variables, and any number that is in front of a variable (multiplication) is called a coefficient. 4 is the coefficient. x can be substituted. A constant is a number that does not change. -110 is the constant.
