Step-by-step explanation:
Answer:
1) 62.5
2) 50
3) 75
4) 100
Step-by-step explanation:
1)
Because it has a half-life of 25 days, half of it will decay after 25 days.
After 
days, there will be 
of it left.
So, 
.
2)
Because it has a half-life of 25 days, half of it will decay after 25 days.
After 
days, there will be 
of it left.
So, 
3)
Because it has a half-life of 25 days, half of it will decay after 25 days.
After 
days, there will be 
of it left.
So, 
.

The only answer left is 
grams. You can solve it the same way you solved the previous steps.
Answer is r32 because it is the square root of an exponent you must divide it.
Answer:
(2,2) , (0,0), (5,3)
Step-by-step explanation:
To check which points are solution to the system of inequalities, substitute the value of those points in the two inequalities and make sure are both true.
y ≤ x
y > -x +1
Point (x=2, y=2)
2 ≤ 2 ✅
2 > -2 +1 ⇒ 2 > -1 ✅
Because both inequalities are true using the coordinates of this point then the point IS a solution to the system of inequalities.
Point (x= -2, y=2)
2 ≤ -2 ❌
We stop checking because we need both inequalities to work. This point IS NOT a solution.
Point (x=0, y=0)
0 ≤ 0 ✅
0 > -0 +1 ⇒ 2 > 1 ✅
This point IS a solution.
Point (x=0, y=5)
5 ≤ 2 ❌
This point IS NOT a solution.
Point (x=2, y= -2)
-2 ≤ 2 ✅
-2 > -2 +1 ⇒ -2 > -1 ❌
This point IS NOT a solution.
Point (x=5, y=3)
3 ≤ 5 ✅
3 > -5 +1 ⇒ 3 > -4 ✅
This point IS a solution.
Point (x=4, y= -3)
-3 ≤ 4 ✅
-3 > -4 +1 ⇒ -3 > -3 ❌
This point IS NOT a solution.
Point (x=-2, y=-2)
-2 ≤ -2 ✅
-2 > - -2 +1 ⇒ -2 > 2+1 ⇒ -2 >3 ❌
This point IS NOT a solution.
Answer:
Step-by-step explanation:
A calculator shows the value of 
meaning that each day, about 99.4% of the sample remains.
The formula 
Evaluate this at <em>t</em> = 16 to get 91 grams remain.
