\bf R_1R_2=RR2+RR_1\implies R_1R_2-RR_1=RR2 \\\\\\ \stackrel{\textit{common factor}}{R_1(R_2-R)=RR_2}\implies  R_1=\cfrac{RR_2}{R_2-R}

The amount in kilograms, a, of a radioactive element that remains after t hours can be modeled by the equation a= 0.65(0.92)to t
elena-14-01-66 [18.8K]

Answer:

The rate of decrease is 8%

Step-by-step explanation:

we know that

The general equation for the radioactive decay can be written as:

a=a_0(1-r)^t

where

a is the amount in kilograms after time t.

a_0 is the original amount of the substance or y-intercept of the function

r is the decay rate, written in decimals.

t is the time

In this problem we have

a=0.65(0.92)^t

so

a_0=0.65\\(1-r)=0.92

solve for r

r=1-0.92=0.08

Convert to percentage

0.08(100)=8\%

Simplify this expression leaving your answer in index form​
kenny6666 [7]

Answer:

solution is 9a^16

Step-by-step explanation:

(6)^2= 36

(a^5)^2= a^25

36a^25/(9a^9)

(36/9)= 4

(a^25)/(a^9)= a^(25-9)= a^16
