the population of the united states can be modeled by the function p(x) = 80.21e^0.131x where x is the number of decades (ten year periods) since 1900 and is the population in millions. a. graph p(x) over the interval 0 lower or equal to x and lower or equal to 15. b. if the population of the united states continues to grow at this rate, predict the population in the years 2010 and 2020.

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.

the answer is 45 i just did it on oddesy ware

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
