Answer:
I believe it would be A
Step-by-step explanation:
A deck of cards has 52 cards in it, so it cant be C or D, and with all the possibilities it could not be B
To find the answer, use 
, and then use the equation 
To find it's half life.
18- j
19- c
20- h
Hope this is right lol
First find the slope,
m=(y2-y1)/(x2-x1)=(1-(-9))/(7-6)=10
Next, use the point slope form to find the equation:
L : y-y1=m(x-x1) => y-1=10(x-7)
[in point slope form, point is (7,1), slope=m=10 ]
Answer:
3 centimeters
Step-by-step explanation:
The diameter is 2 times the radius, meaning 6/2 is 3.
