Yep
9.12 is a terminating decimal, which means it is rational. It can also be represented as a ratio of two integers (912/100). An irrational number, on the other hand, cannot be represented as a ratio of two integers.
According to my calculations it is 21
This is a pretty easy half life problaem.
There are formulas for calculating this using "e" but I have a simpler formula which you can find here:
http://www.1728.org/halflife.htm
Ending Amt = Beginning amount / 2^n
where n is the number of half-lives
n = 1
Ending Amt = Beginning amount / 2^1
Ending Amt = 1,000 / 2
Ending Amt = 500 grams
Answer:
0, 7 )
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 8x + 7 ← is in slope- intercept form
with y- intercept c = 7 ⇒ (0, 7 )
