Answer:
2
Step-by-step explanation:
Average Rate of Change:
Step 1: Define variables
f(b) = 5
f(a) = 3
b = 2
a = 1
Step 2: Plug into formula
(5 - 3)/(2 - 1)
2/1

9 = m
Hope this helps. Pls give brainliest.
DI/dx=-850x+45500
d2l/d2x=-850 so when dl/dx=0 it is an absolute maximum for l(x)...
dl/dx=0 only when:
850x=45500
x=53.53
x=54 years of age (rounded)
Answer:
-1/18
Step-by-step explanation:
Let's multiply left and right by 3n:
2 = -12 * 3n =>
-36n = 2
now divide by -36:
n = 2/-36 = -1/18
Radiologically, half lives describe the amount of time it takes for half the amount of the radioactive substance to decay. If you had 100g of a radioactive substance with a half life of one week, in seven days, only 50g would remain, and after another week, only 25g.
Fifteen days contains three half lives since the half life is 5 days long. Divide the starting amount by 2 for each half life that passes.
600g - 300g (1 HL) - 150g (2 HL) - 75g (3 HL)
So, only 75g of Bismuth-210 would remain after 15 days.
