The first time a census was taken in esinville, the population was 12,621. each year after that, the population was about 6% higher than it was the previous year. sketch the graph that represents the situation. let x represent the number of years since the first census was taken. what are the coordinates of the point that contains the ­y-intercept? (1, 12,621) (0, 12,621) (12,621, 0) (1, 12,621)

Marcus needs to rewrite f(x) = x2 + 6x + 4 in vertex form.

Atextile fiber manufacturer is investigating a new drapery yarn, which the company claims has a mean thread elongation of 12 kilograms with a standard deviation of 0.5 kilograms. the company wishes to test the hypothesis upper h subscript 0 baseline colon mu equals 12 against upper h subscript 1 baseline colon mu less-than 12 using a random sample of n equals 4 specimens. calculate the p-value if the observed statistic is x overbar equals 11.8. round your final answer to five decimal places (e.g. 98.76543).

(fog)(x) if f(x)=x^2- 4 and g(x)=x^2 + 2 x, f(g(x))= f(x^2+2x) (x^2+2x)^2-4 (x^2+2x)(x^2+2x)-4 (x^4+2x^3+5x+4x^2)-4 x^4+2x^3+4x^2+5x-4 what am i doing wrong
