The exponent is not the number of years or the number of hours.
The exponent is the number of half-lifes.
In this one, the half-life is 12 hours, and they want to know
how much is left after 36 hours. 36 hours is 3 half-lifes.
The formula that you did is beautiful and almost perfect.
Just change that ugly exponent to the number of half-lifes (3)
and the answer will jump out at you.
F=P(1/2)^(t/h)
F=furure or ending amount
P=present amount
t=time elapsed
h=time the half life is
F=64(1/2)^(36/12)
F=64(1/2)^(3)
F=64(1/8)
F=8 grams

C) E=3G+2
D) G=3G+2

Answer
The equation shows this situation is Option (B) .
i.e G=2E+3
Reason
As given
Gary is 3 years older than twice the age of his sister (Elena) .
Let us assume that the age of the Gary be G.
Let us assume that the age of the Elena be E.
Than the equation becomes
E = 2G + 3
Therefore option (B) is correct .
The first thing we must do for this case is to define variables.
We have then:
G: Gary's age
E: Elena's age
We then have the following expression:
Gary is 3 years older than twice the age of his sister (Elena):
Using the defined variables, we can write the expression as:
G = 2E + 3
Answer:
an equation for this situation is:
B) G = 2E + 3

H+1/2= 3 1/4
H is a variable, so it must have a value to it. So it would be 2.75+1/2= 3 1/4
Or 3 1/4 / 1/2 = 2.75

Answer:
x =4
Step-by-step explanation:
2 ln x = 4 ln 2
Divide each side by 2
2/2 In x = 4/2 In 2
ln x = 2 ln 2
Remember that a ln b = ln b^a
ln x = ln 2^2
ln x = ln 4
We are taking the natural log on both sides so , what we are taking the natural log of must be the same
x =4
Answer:
4
Step-by-step explanation:
Use the property of logarithms . (The number in front of ln becomes an exponent--or vice versa!)
Using that property on both sides, you get
But that means
Notice that is not a solution because
is undefined. Negative numbers do not have logarithms. The domain of
