the half life of a radioactive isotope is the time it takes for a quantity of the isotope to be reduced to half its initial mass. starting with 165 grams of radioactive isotope how much will be left after 4 half lives.

Answers

Dividing the weight of the radioactive isotope from 4 halves that is 16, the left weight of the radioactive isotope after 4 half-lives is

⇒ 10.3 grams

Given that,

The half-life of a radioactive isotope is the time it takes for a quantity of the isotope to be reduced to half its initial mass.

Here, Starting weight of the radioactive isotope is, 165 grams

Hence, the left weight of the radioactive isotope after 4 half-lives is,

⇒(165)/((2*2*2*2) )

⇒ (165)/((16) )

⇒ 10.3 grams

FIND THE VALUE OF x³=-8
A ±4
B ±2
C-2
D-4

Answers

Answer:

x=-2

Step-by-step explanation:

In this kind of question,we will have to be extra careful to prevent errors or mistake.reason for the errors and mistake is that there is a negative sign in front of the 8...so any solution must ensure to involve the negative sign...or else the final answer will be discarded...

So back to the question

X^3=-8

Which means that the cube of x is 8 and we are to solve for x, therefore to solve this question...we will have to cube root both sides...why

So as to eliminate the cube on x...

Ok how,cube root of x^3 can also be written as x^3×1/3 which gives x

And cube root of -8 will be either 8^1/3 or3√-8

And the answer is-2

To confirm the answer we can say -2×-2×-2=-8

So the final answer is -2

Therefore x=-2

Answer:

C.) \: \: \: - 2

Step-by-step explanation:

({ - 2})^(3) = - 8
