Section 6 - Topic 2 Nature of the Zeros of Quadratic Equations and
Functions
1.
Use the discriminant to determine if the following quadratic equations
have complex or real solution(s). If an equation has real solution(s).
determine the solution(s).
Part A: 4x2 – 3x - 10 = 0
Part B: x2 – 14x + 49 = 0
Part C: g(x) = x2 - 8x - 20
Part D: h(x) = x2 – 9x + 36
Part E: 3(x + 2)2 + 26 = 0

Asample of 200 rom computer chips was selected on each of 30 consecutive days, and the number of nonconforming chips on each day was as follows: the data has been given so that it can be copied into r as a vector. non. conforming = c(10, 15, 21, 19, 34, 16, 5, 24, 8, 21, 32, 14, 14, 19, 18, 20, 12, 23, 10, 19, 20, 18, 13, 26, 33, 14, 12, 21, 12, 27) #construct a p chart by using the following code. you will need to enter your values for pbar, lcl and ucl. pbar = lcl = ucl = plot(non. conforming/200, ylim = c(0,.5)) abline(h = pbar, lty = 2) abline(h = lcl, lty = 3) abline(h = ucl, lty = 3)
