Radioactive iodine is a dangerous by-product of nuclear explosions, but it decays rather rapidly. Suppose that the function
R(t) = 6 (10-0.038t) gives the amount in a test sample remaining t days after an
experiment begins. Use logs to find the half-life (1/2 or 50%) of the substance.

he will have 300 because he is really broke and 300 is in his imangine

step-by-step explanation: he ehe heh step by the thy

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

so, converting firstly the mixed fractions to improper fractions and then "adding".
