Answer:
=209.09 mg
Step-by-step explanation:
given: material= radium
half life= 1590 years
initial mass
=500mg
we know that to calculate the amount left we use
= 


therefore
= 
=209.09058407921 mg
=209.09 mg amount left after 2000 years
Answer:
1/3
Step-by-step explanation:
let a = adults
so then 2a = children
a/2a(+a) = a/3a
A) the slope of the equation is 5, the y intercept is 10.
b) the rate of change is just the slope, so 5 but it means that they are picking 5 berries over that period of time. the initial amount is just the y intercept which is 10. this is just how many berries you start with.
c)
Answer:
Table:
1: f(x) = 5
2: f(x)= 6
5: f(x) = 9
Points: (1,5), (2,6), and (5,9)
Step-by-step explanation:
1. The function f(x) = x + 4 means that 4 is added to the input, x, to get the output, y.
Therefore, when x = 1 then f(x) = 5, x = 2 then f(x) = 6, and x = 5 then f(x) = 9.
2. Now, to find the points, we must know that x is the x-coordinate and f(x) is the y-coordinate of the point. Because of this, the points are:
Therefore, the points are (1,5), (2,6), and (5,9).
It’s basically tell you to bring it down by 10 so it’s (5,-6)
