If f(x) = 5x^3 and g(x) = x+1, find (fg) (x)

Hi my sisters and brothers can tell me the answer because i don’t understand the question

State if the two triangles are congruent. if they are, state how you know?

The fraction of defective integrated circuits produced in a photolithography process is being studied. a random sample of 300 circuits is tested, revealing 17 defectives. (a) calculate a 95% two-sided confidence interval on the fraction of defective circuits produced by this particular tool. round the answers to 4 decimal places. less-than-or-equal-to p less-than-or-equal-to (b) calculate a 95% upper confidence bound on the fraction of defective circuits. round the answer to 4 decimal places. p less-than-or-equal-to
