Answer:

A

Step-by-step explanation:

Since each star is worth 50 points, if 5 stars are zapped that would convert to 250 points. Each level the number of stars increase by 5, level 6 would have 45 stars and so on.. With level 10 having 65 stars to complete.

Radium-226 has a half-life of 1620 years. for a 150 gram sample, how many grams will remain after 200 years?
VashaNatasha [74]
Ah, yes

if you start with P amount of something and the half life is h units (in years) and the time elapsed is t (in years) then the amount left is A

the equation is
A=P(\frac{1}{2})^\frac{t}{h}


so
given
h=1620
P=150
t=200
so
A=150(\frac{1}{2})^\frac{200}{1620}
A=150(\frac{1}{2})^\frac{10}{81}
use your calculator
A≈137.69781917515g
about 138grams left

Lunna [17]

f(x)=lnx

y=f(x)

dy/dx= 1/x

tangent at (x,y) has slope 1/x

eqn of tangent is y = mx + c

since the tangent passes through origin, c=0

substitute y = lnx and m= 1/x to above eqn

lnx = 1

x=e

y=lne=1
