Answer:
the one that looks like a V
1. take a ruler
2.move it across the graph
3.see if it crosses twice
ex:if it is a straight line than it wont work if it is like a V shape it will work
Answer:
2,674.14 g
Step-by-step explanation:
Recall that the formula for radioactive decay is
N = N₀ e^(-λt)
where,
N is the amount left at time t
N₀ is the initial amount when t=0, (given as 42,784 g)
λ = coefficient of radioactive decay
= 0.693 ÷ Half Life
= 0.693 ÷ 18
= 0.0385
t = time elapsed (given as 72 years)
e = exponential constant ( approx 2.7183)
If we substitute these into our equation:
N = N₀ e^(-λt)
= (42,787) (2.7183)^[(-0.0385)(72)]
= (42,787) (2.7183)^(-2.7726)
= (42,787) (0.0625)
= 2,674.14 g
No, it is an imaginary number.
Can't take the square root of a negative number without creating a method termed an imaginary number, which is the square root of -1 which they have used " i " to signify.
Then square root of -11.2 would be written Sqrt(11.2)i. The Sqrt(11.2) = 3.3466
so the answer is 3.3466i
Hello!
You have to find the probability of getting a 2
This is a 1/6 chance
Then you have to find the chance of getting a number greater than 2
This is a 4/6 chance
To find the chance of these happening at the same time you multiply these together
1/6 * 4/6 = 1/9
There is a 1/9 chance
Hope this helps!
