Answer:
A
Step-by-step explanation:
3x9+ 27 + 8= 35
The formula on nth term is l=ar^(n-1)
The 1st term is 2 & r,the ration =3
Then is 2x3^(n-1). Mind you (n-1) is an exponent on 3
The answer is 201 hope this helps
The amount of the substance (At) at any time t is calculated through the equation,
At = (A0)(e^-kt)
where A0 is the initial amount and k is constant.
For the half-life,
ln (At / A0) = ln 0.5 = -k(5270 years)
The value of k is 1.3153x10^-4 / year.
Substituting this value to the same equation, where At = 0.25A0
ln 0.25 = -(1.3153 x 10^-4)(t)
The value of t from this equation is 10540 years. The closest value to this is letter A.
Answer:
7
Step-by-step explanation:
difference between two number let say x&y is x-y
so, difference between their score is (-17)-(-24)
=(-17)+24 {minus of minus is plus}
=24-17
=7
