*Use the Pythagorean Theorem
a^2 + b^2 = c^2
6^2 + 5^2 - c^2
36 + 25 = c^2
61 = c^2 *Square root 61
c^2 (c squared) = about 7.8
Answer:
60.5 milligrams per square centimeter First, determine how many half lives have expired by dividing the time by the half-life. So: 55/20 = 2.75 That means that only 2^(-2.75) = 0.148650889 = 14.8650889% of the original substance remains. So just divide the amount remaining by 0.148650889 to get the original amount. 9 / 0.148650889 = 60.5445419 So originally, there was 60.5 milligrams per square centimeter 55 years ago.
Answer:
6
Step-by-step explanation:
8(1/4) is 2 bc 1/4 of 8 is 2
2-1=.5(10)
.5 works like 1/2 so 1/2 is 10 is 5
then you get 2-1+5 then after that you get 6
Answer:
Step-by-step explanation:
A linear function is always a one-to-one function.
Switch y and x.
x = -8y + 1
-1/8x + 1/8 = f(x)
