Answer:
after 42 mm the next one is 63mm and after 198mm it is 946mm
Step-by-step explanation:
By definition, the half life is a quantity is the time it takes to lose half of that quantity.
So, if the half life is 60 days, it means that after 60 days you have lost half the initial amount, i.e. you're left with 100 grams.
After another 60 days, you've lost, again, half of that amount, so you're left with 50 grams.
In other words, every time a half life period passes, you're left with half the quantity you had at the beginning of that period.
So, after two half-life periods (i.e. 120 days), you'll have half of the half of the initial quantity, i.e. one quarter.
Answer:
The rotational angle of a regular polygon with 72 sides is 5º.
Step-by-step explanation:
The rotational angle (
), measured in sexagesimal degrees, of polygon of 
sides is the angle of a complete revolution divided by the number of sides (). That is:
(1)
If we know that 
, the rotational angle is:
The rotational angle of a regular polygon with 72 sides is 5º.
1) plug -5 in for the place of x.
2) solve -(-5)^2
3) f(-5)=25
