A radioactive isotope decays exponentially at a rate of 0.0119% each year.

How long will it take 500 g of the isotope to decay to 150 g? Round your answer to the nearest whole number.

It will take about years for 500 g of the radioactive isotope to decay to 150 g.

The half-life for a radioactive isotope is the amount of time it takes for the isotope to reach half its initial value. What is the half-life of the given radioactive isotope? Round your answer to the nearest whole number.

The half-life of the given radioactive isotope is about years.

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

darn right!
