The half-life of strontium-90 is 28 years. Suppose we have a 52 mg sample.
(a) Find a function that models the mass m(t) remaining after t years.
m(t) =
(b) How much of the sample will remain after 60 years?
m(60) =
mg.
(c) How long will it take the sample to decay to a mass of 13 mg?
Your answer is
years.

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1

is there a graph
