Staals half
1 gram left
0.3 grams left
half lives are normally written in years
it goes likt this

A=P( \frac{1}{2})^ \frac{t}{h}
A=final amount
P=initila amount
t=time elapsed
h=time half life is (same units as time)

let's use days as the units of time


we are given
initial amount=1gram
final amount=0.3gram
time=4 days

so
0.3=1( \frac{1}{2})^ \frac{4}{h}
solve for h
0.3=( \frac{1}{2})^ \frac{4}{h}
take the ln of both sides
ln(0.3)=ln( \frac{1}{2})^ \frac{4}{h}
ln(0.3)=\frac{4}{h}ln( \frac{1}{2})
times both sides by h
hln(0.3)=4ln( \frac{1}{2})
divide both sides by ln(0.3)
h= \frac{4ln( \frac{1}{2}) }{ln(0.3)}
use calculator
h=2.30287
3 sig figs
h=2.303 days

Trigonometry please help! work need to be shown
padilas [110]

Answer:

x = 5.56

Step-by-step explanation:

Apply trigonometric function to find x

Reference angle = 46°

Hypotenuse = 8

Adjacent length = x

Apply CAH:

Cos 46 = Adj/Hyp

Cos 46 = x/8

8 × Cos 46 = x

5.55726696 = x

x = 5.56 (nearest hundredth)
