The half-life of rhodium, Rh-106, is about 30 seconds. You start with 500 grams.

I think the logical question for this would be to find the reaction rate constant, k, for radioactive decay of Rhodium. The general formula is:

ln A/A₀ = -kt,
where 
A is the amount of substance after time t,
A₀ is the original amount of substance
t is the time

After 30 s, the amount of Rhodium would be in half. So, A/A₀ = 1/2

ln(1/2) = -k(30 s)
k = 0.023 s⁻¹

Translate the sentence into an inequality.
grigory [225]

Answer:

8b + 27 ≤ - 29

Step-by-step explanation:

Sum of a number can be written as x or in this case as b because it is an unknown number.

b is multipled by 8 so 8b

"and 27" indicates an addition so therefore, 8b + 27

"at most -29" This is a little bit tricky but ultimately it means 8b + 27 cannot be more than -29. Therefore, it must be lesser than.

However there is a line underneath that lesser than sign meaning lesser than or equal to. I believe that "at most" indicates equal to.

Other than the lesser than or equal to sign I'm unsure about, this inequality should be correct.

15 points and crown <br> solve by factoring (x+6)(2x-5)=0<br> I am confused
Reika [66]
Remember, in order for this equation to be true either one of the polynomials has to equal 0
So:

-> x+6 = 0

x=-6


-> 2x-5 = 0

2x= 5

x= 5/2


So the answer is x=-6 and x= 5/2.


Hope this helps!

Calculate the average rate of change for given function, from x=2 to x=7
LenaWriter [7]
"When you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. f(x) = x2 and f(x + h) = (x + h) Therefore, the slope of the secant line between any two points on this function is 2x + h."

which is approximately 16.5
for the second question
we also use Pythagoras
b^2=c^2-a^2
\sqrt{13^{2}-12^2}=5
