One hundred grams of radium are stored in a container. Rp = initial amount, R = current amount, 1600 years = half life for radium226, t = time elapsed (Initial to current years),
To the nearest year, how many years must pass for 5 grams?

step-by-step explanation:

first you will have to convert 3/4 into a decimal

no you have to divide

is there a picture

step-by-step explanation:

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

1 and 0
